What PA's to get for frat basement (Coax worth or not)

Hi, I'm managing a project for replacing the sound system for my frat's basement and was wondering about the kind of speakers I should be getting.

The thing is the basement we have is a tight 8mx15m space with ceilings about 8-10ft high, the basement is always packed to the point where people are right next to our speakers so i was wondering if coaxial speakers are kind of a requirement.

Currently our setup is 2 JBL JRX125 tops and 2 JBL SoundFactor SF15 with 2 subs that I don't know what they are honestly the speakers currently sound like shit probably because they're old and the amp is fucked so we're completely replacing the system, I want to keep a similar loudness level (the JRX125s are like 133db SPL i think) but I was noticing that speakers with the same db rating that are also coaxial are much much more expensive, our budget is around 15k and I'm looking to get 4 tops and 2 subs.

Our budget is in the ballpark of 15k and these were the two options I was looking into

4× JBL SRX812P + 2× SRX828SP (Non-coaxial) 135dB SPL per top

4x or 6× Tannoy VXP 12 + 2× SRX828SP (Coaxial) 131 dB SPL per top

I was wondering for this case with a packed basement how important coax is and is it worth losing the loudness. Also curious what the word is on passive vs powered systems at this price point and I've heard powered speakers are dangerous when people with drinks are nearby so let me know if that is a huge worry or not. I'm new to this speaker stuff so any advice would be appreciated! I'm also curious what other things I should be worried about with speakers and if things like driver size are important to look at like if i want to SRX812s or SRX815s for example. Appreciate the help!

Update 2#: my virtual WING (running the real firmware) now makes sound, with EQ and compression, slowly

Follow-up to https://www.reddit.com/r/livesoundgear/s/htqXGb10zX about a software WING that runs the console’s own firmware (WING Rack 3.1.1) instead of a re-creation of it. The goal is still a real virtual sound check at home: play back a multitrack recording through the actual WING’s processing on my PC, and mix it on the console’s own interface.

Last time I ended with a list of what didn’t work. Here’s where those stand:

  • No audio → it plays sound now. Audio goes through the console’s own emulated input and bus DSPs and out of MAIN 1 on my speakers. My Scarlett comes in as local inputs (didn't show in the video), and a WAV loops on USB 1/2 (in the video).
    • When I move a fader on WING Edit, the firmware itself writes the new value into the DSP that’s making the sound.
    • Which channel hears which source comes from the firmware’s own routing.
    • EQ and the compressor work too. Changing them on the console’s screen changes what I hear, because the console’s own EQ and dynamics run on the emulated input DSP.
  • No network → WING Edit connects. The console answers discovery, and WING Edit talks to it like a real WING.
  • About a third of real time → the console runs at about half real time. The audio DSPs run at about 0.6×, and that’s the catch: the sound has gaps. The audio itself is correct (an offline render of the same DSP state comes out clean); there just isn’t enough of it per second yet.

One thing to know while watching: when I click out of the command window (the emulator runs from there and isn't shown in the video) into the browser to change something, the sound gets noticeably worse: more gaps and more crackle. That’s not the EQ or the compressor doing it; it happens just by switching windows. Windows gives the window you’re using more CPU time than background ones, and the emulator is already short on speed. Most likely it loses just enough when it’s in the background to get worse. With the command window focused, it’s only gaps.

What’s still missing:

  • Speed. Each DSP runs on one CPU thread flat out, while the rest of the CPU sits mostly idle. The next step is spreading each DSP’s work over more cores.
  • The FX DSPs in the live path. They boot and run, but FX inserts are silent live for now.
  • The XMOS and the FPGA’s audio side still aren’t emulated. My own code moves audio in and out of the DSPs where the FPGA would, and it takes the routing from the firmware itself.
  • No comparison against a recording from a real WING yet.

The setup is the same as before. The i.MX6 ARM application runs on Unicorn. The four ADSP-214xx SHARC DSPs run on an interpreter built for this project, with a C version checked against it instruction by instruction.

What’s new is that the DSPs answering the console are the same ones making the sound, each in its own process. Between blocks of audio, each one takes the console’s control messages through its own firmware, exactly as it does on the real hardware.

Is my setup idea good enough? Asking for suggestions and corrections (Newbie here)

Hello, I'm trying to setup a IEM and backing track playback rack based around the Behringer XAIR-18 and would like to hear some suggestions.

My budget is very limited and my goal is to make this as portable and simple as possible.

We are a 4 piece metal band but we rely on backing tracks to give more weight to our songs live (ambience sounds, weird effects, synths). My rationale is:

"If we depend on backing tracks for our show, we might as well use a laptop for all the sound processing, including our instruments.

That way we don't need to carry around with pedalboards and that kind of stuff, we can automate everything. We simply plug into the mixer and we are good to go."

For now, I'm considering going with wired IEMs to keep the cost down and have as much options for IEM mixes as we can.

This is the basic idea:

  • Macbook Air M4 16GB RAM
  • Reaper running amp sims and voice effects (Neural DSP, Tonex, etc...)
  • Reaper to create a shared stereo IEM mix + click using the XAIR USB 3-4 channels
  • XAIR18 as an interface for our instruments to the plugins
  • GTR 1 and GTR 2 to the Hi-Z inputs of the X-AIR
  • Direct box for the bass
  • XAIR18 to create a MIX for FOH
  • XAIR to create custom MONO IEM mixes (Aux outputs)
  • Behringer P2 IEM amps for monitoring

I've tested this setup in my house and rehearsals and the latency in the IEMs is actually pretty good, almost not noticeable.

Now, I've some questions:

Drums and IEM cheating:

  1. To keeps thing simple, I would prefer not to mic the drums live. My idea is that everyone but the drummer hears a pre-recorded drum track on the IEMs. While the drummer can have a custom IEM mix without it, but would he be able to hear his playing well enough?
  2. If the above is not a good idea, I guess a basic condenser mic close to the drums could be good enough?
  3. If the venue has their own drum mics, could we ask for a drum only mix so we can route it to the drummer IEMs?

Stereo IEM Mix:

I'm planning on using the IEM stereo mix from the DAW using the XAIR USB 3/4 channels and use the headphone output of the X-AIR for it to save AUX busses. Since this mix is intended to be shared by most of the band, I want to find the best way to multiply this signal for at least 4 people.

  1. Can I use a Jack to XLR cable in stereo from the X-AIR headphone output to a passive XLR 1in-4out splitter?
  2. (or) Can I use two AUX busses from the X-AIR based on the USB3/4 channels and then use a custom XLR Stereo combinator cable to a passive XLR 1in-4out splitter? (I modified a Y splitter cable so I can combine two mono signals into a single stereo XLR)

I've tested option 2 at home and it works well, but I'm not sure if this is the ideal way or if it will work with passive splitters.

I know the XLR will be unbalanced if I force it to carry a stereo signal, but the venues where we play are not that big so I hope there are not going to be many noise issues. Worst case scenario we use the MONO IEM mixes from the AUX busses on the X-Air.

FOH Questions:

  1. Am I being too optimistic thinking any venue would let us simply send the main L/R outputs from the X-AIR to FOH and control our own mix and eq?

EDIT: Forgot to mention that our FOH is stereo and mono compatible. Most cases it will be mono.

Please feel free roast my idea as hard as you like, I'm here to learn. Thanks!

Insane feedback at corporate meeting

I'm not a live sound engineer, I tune the audio in ambulance/police radios, but I'm always told to do the live sound for company-wide corporate presentations for the CEO and top level management. I'm not very good but there is no one else.

They insist on using lapels and I really struggle with feedback. I feel like I've done everything I can:

- swapped to cardioid lapels

- moved the speakers as far forward and as wide apart as possible (they seem to always stand right next to them no matter where I put them)

- tried to give them a brief of what to do (most don't listen)

- made sure the mics are placed correctly (because they insist on lapels, they swap them around because we only have 3, so they end up in all sorts of funny positions, sometimes upside down)

- sent the mixer outputs to a sound card for parametric EQ (has crashed twice recently - i know this isn't a great thing to do but it's all I have)

Despite all this, I still get insane feedback and I struggle to get people to understand. They always think I'm an idiot for not just 'turning it up'. I'm 99% sure it's the room causing the issue. We do it in our cafeteria and the ceiling is quite low.

Does anybody have any tips for what I could try next? I thought about trying to suggest the idea of headsets instead?

EV Evivia 12P vs Alto TS412

I’m currently looking at buying a lower priced PA system to occasionally DJ parties and small bars of no more than 40 people. I was looking at the Evivia line from Electro Voice as I’ve heard that it’s a reputable brand in the audio industry. What confuses me is why is this particular line is selling less than the Alto brand series of the same size speaker. I’ve heard that alto isn’t a great brand in terms of quality and build. Does anyone know why this is? Is the Evivia line not great either? The Eviva 12P is currently selling at $369 and the TS412 is currently selling at $399.

Looking for the best cheap mic to record a small gig

Hi, im going to a small gig in December, probably only 100/150 people in a church. I usually record these gigs on my phone but the audio is obviously not great.

Are there any cheap, small mics that can hook to a phone that will record better audio? Doesn't need to be pro quality. Just better than what I usually get.

The ones I keep seeing online are for voice recording and im not sure if they'd record the room audio too.

Any help would be appreciated

Seeking directional speaker recommendations for a museum exhibit

I've been contracted to design sound for an exhibit at a children's museum about "being inside a thunderstorm and rainbow."

It’s a pretty small exhibit area with an open-floor plan, targeted to toddler age, and with a live foley component (thundertubes, rainsticks, etc). I am deeply concerned about sound bleed so I'm researching directional speakers. (Which will be supplemented by subwoofers and some practicals.)

I'm looking at Dakota Audio (FA-501), Brown Innovations (CT24-24 or Wide Dispersion Localizer Sound Dome), Focusonics (Model A) and Soundtube (FP6020-II).

What I’d like is for visitors (say, a small family) to be able to go to each area (maybe 7’x7’?), stand there and be immersed in the storm for a few minutes while looking at whatever it is they’re looking at, and then move on to the next area and listen to that storm phase, but without having to hear too much of the other areas. In other words, sort of a curtain of sound blended around the room but specific details as you move around each "area" and explore the storm.

I have no idea what the museum’s budget is. They told me to do the research and they’ll let me know!

Thoughts on the above brands? Or others? Or best practices? I have never done this before and neither has the museum.

College Marching Band Setup

I am attempting to create a live sound setup for my college marching band.

We currently have an electric guitar and electric bass running through a fender hotrod deluxe and a boss katana respectively. We've been noticing issues with hearing the instruments against the rest of the band, especially as we utilize the guitar for a lot of solo moments.

My director wants to make it as “plug and play” as possible, while remaining future proof for the future generation of our pit.

Right now we are dealing with a very unconventional pit, Being the guitar and bass previously mentioned, and a single Marimba. We are fighting a 98 piece band. 

Our budget is ~$3000

Any suggestions?

Powered speaker recommendation for a mostly solo acoustic musician - RCF/Yamaha/QSC/Bose/etc.?

I'm a gigging acoustic musician putting together my first proper portable PA and have gone far enough down the rabbit hole that I could use some advice from people who actually work with this stuff.

Current situation:
I play solo acoustic gigs and sometimes have a friend or two sit in for a couple songs. I've been using a Fishman Loudbox Performer, but it just died during a gig, which accelerated my plans to put together a real PA.

For solo shows I'm primarily running vocals plus acoustic instruments - guitar, resonator, banjo, etc. Sources include pickups/pedals going direct, but sometimes just use an SM81 to mic all the instruments if I'm going to switch around a lot.

I'm planning on buying a small mixer with phantom power (currently looking at a Yamaha MG10XU) and initially one good powered speaker on a stand. I own a Bose S1 Pro that I can use as a personal monitor.

Typical use would be small-to-medium bars, breweries, restaurants, outdoor tents/festivals, etc. I'm not trying to provide sound for a 500-person rock show. For larger gigs I generally plug into house sound anyway.

Long term I'd like something I can keep for many years, potentially add a second matching speaker later for when I make it big (HA!), and occasionally contribute to the PA/monitor setup for other bands I'm in.

I've looked at everything from portable suitcase systems to:

  • QSC K10.2
  • Bose F1 812
  • JBL EON/PRX
  • Yamaha DXR
  • RCF ART 910-A

I initially leaned heavily toward the K10.2, but the Protect Mode 4 reports and stories of failures during gigs have given me some pause. I realize the majority of owners don't have problems, but reliability is pretty high on my list - especially after my amp just died mid-gig.

The Bose F1 812 also interests me. I generally love Bose gear and sound, but it's substantially more expensive and heavier.

At this point I'm less concerned about finding the cheapest solution and more interested in buying something that:

  1. Sounds excellent for vocals and acoustic instruments
  2. Is extremely reliable
  3. Has enough headroom for small/medium gigs
  4. Is reasonably portable
  5. Can serve as a main, monitor, or part of a larger system as my needs change
  6. Is something I'm unlikely to feel the need to replace in two years

If you were starting with one powered speaker + mixer for this use case today, what would you buy?

I'm especially interested in long-term experience from people who regularly use these speakers live.

Compact subs for a tiny live-band venue — dual 8s vs 10s?

We play a recurring gig at a very small restaurant/café (roughly 60 people max), and I’m looking for some opinions on adding a pair of really compact subs.

Our current PA is a pair of original QSC K10s. They actually handle the room surprisingly well, but we’re definitely missing some low end whenever we have electric bass or our drummer brings a Roland HandSonic. We don’t need club-level bass — just enough 50–100 Hz-ish reinforcement to give the bass/kick some actual weight and take some of that work off the K10s.

I already own two QSC KS112, but it’s honestly too large for this particular room. There’s basically no usable place for a center sub without taking up dance-floor space.

The weird part about our setup is that the K10s also have to sit behind the band. There isn’t room to put them out front, and we currently use them partially as our monitoring since we don’t have wedges and only have 2 IEMs mixes at this gig.

So what I’m thinking is:

K10 short speaker pole compact sub

on each side of the band.

That would actually take up less usable floor space than our current tripod stands while adding the little bit of low end we’re missing.

The three options I’ve been looking at are:

2x Rockville TITAN SLIM D8 — dual 8", very shallow cabinet, plywood, M20 pole mount. About $600/pair.

2x Rockville RBG10S V2 — single 10", much lighter and cheaper at roughly $420/pair.

2x Sound Town CARME-110SPW — single 10" folded-horn design, plywood, roughly $620/pair.

The TITAN SLIM D8 is the one I’m currently most interested in because that super-shallow form factor looks almost perfect for this room. With two of them we’d have four 8" drivers total, and we’re not looking for huge SPL — just clean bass reinforcement for an 80-person restaurant.

My main questions:

Has anyone actually used the TITAN SLIM D8? How does it perform in the real world?

Would two dual-8 subs be enough for electric bass + electronic kick in a room this size?

Would you choose the dual-8 Titans over a pair of small 10" subs for this application?

Any concerns about putting a K10 on a short pole above something this narrow?

Is there another very compact/shallow powered sub around $300–400 each that I should be looking at instead?

Again, this isn't replacing our larger PA/sub setup. This would basically be a dedicated tiny restaurant rig where portability and footprint are almost as important as output.

Would love to hear from anyone who's used these little subs in an actual live-band application rather than just DJ/background music.

Could anyone reccomend me some nice strong, and quality compression drivers that will screw right onto the original waveguides in my JBL TR225 cabs? I Believe the original ones are 8ohm

Had a tweeter blowout a while back, I replaced it with a cheap ebay diaphragm and now its like my horns are fighting eachother, sounds horrible and harsh. Not even an EQ tune can get it to sound nice

Best powered 12’s in the $500-$700 range for vocal/bass practice w/backing tracks?

I need something mainly for vocal practice with backing tracks. But I would also like to use them with a modeler to practice bass.

I would like something that’s powerful enough to play the occasional bar/party that doesn’t have a PA available.

I use Bluetooth a lot. I could buy an extra receiver if there was a really good sounding pair that didn’t have one. But the convenience would be very nice, all things being equal.

I really like the feature set of the EV ZLX-12p. Bluetooth and the high Z plus the built-in mixer features. But I hear a lot of “Yamaha db12 or ART 712 sound way better”

If I were to gig with them, I do have a single Kali ws-12 sub at 1000w that could add a little more low end.

My genres vary wildly but I’m focused on R&B and very hard rock. Any help is appreciated.

Does a clamp exist for this?

Right now, my band has two subs, with poles in the middle of them supporting other PA speakers. I also have a PA speaker off to my left that basically functions as my amp.

However the stand for it takes up space on the floor

Is there a clamp that can support a PA speaker and hook right up to the other speakers I just mentioned? (the pole that goes into the sub)

Playing at a wedding, but I need an AMP. Please guide me.

Hello Reddit.

I'm DJing at my friend's wedding in April next year, and I own a JBL Cabaret Series Speaker model 4691b rated for 40 HZ to 20K Hertz, 8 ohm impedance, 103 DB at 1 watt 1 m, 200W - 400W continuous, passive speaker that I've just had for a while sitting around.

The speaker is quite old and was a gift from a friend who moved to a different state. But since I already have DJ equipment, thought maybe it would come in handy to play at this party for about 100 people outdoors without needing to rent too big of a system.

The reason I never used this is I don't have an amplifier yet and my understanding is quite limited when it comes to the technical side of power ratings and audio routing, so I need some guidance on which amplifier would safely deliver the power this speaker needs without straining the amp or speaker. My understanding is that I would need an integrated amp since it would already have a pre-amp and power amp in one unit, is that right?

From what I also understood reading on this, the higher the impedance the less power it needs to run at high volumes? Please correct me if I'm wrong. Also can someone please explain the switch that flips between Bi-amplification and Full Range modes, and which setting I should have it at if I'm not running a subwooer separately? This would not* be the only main speaker facing the crowd. Any help is welcome. I've added some photos for specifics that may help you help me.

Thanks a lot in advance yall! <3

Need opinions on JBL passive Mpro series sound quality

Found what I think is a good deal on a set of used passive MP 415 tops and MP 418s speakers. I tried to do a deep dive on these and found limited information. I know it’s subjective but was hoping to get a general opinion on their sound quality. The specs look good, as do the plywood construction. For context, I have a touring band that often plays venues without any live sound equipment. I run drum machines, synths and vocals through the PA and want a good electronic dance music type set up with good separation of elements and decent sounding vocals. I have had my eye on a RCF active set up but I cannot afford it at this time. All four of these speakers are a quarter of the cost of one RCF nx932! I don’t expect these JBLs to be on par with RCFs but thinking they might fit the bill. I am planning on pairing this set up with an XR 18 digital mixer, appropriate spec crown amps, and some sort of crossover limiter set up. Thanks in advance.

So I have seen and read the marketing fluff about the new V8, but I cannot de-cypher the fluff. Is it just an excuse to release a "new" microphone and charge more money?

Disclaimer: I have been impressed with sE mics, the V7 in particular are staples for the live shows I put together in untreated rooms. So I'm the last person to poop on sE but I'm really confused about what the selling point is.

Crossover settings for EV ZLX-12P top and EKX-15SP sub?

If you have used this combination before, which crossover settings do you use? The Hz setting, or the named setting?

My band has an EV EKX 15" sub and Yamaha DXR10 tops that we use for most shows, and we choose the manual crossover point on all boxes (usually 120 Hz).

We're going to play a venue next weekend that has ZLX 12 tops and no sub, so they said we can bring our sub. We won't be able to test different settings, so I'm looking for advice on whether it's better to use the Hz or the name options. I suspect there isn't much difference, but let me know if your experience is different.
