r/SoundSystem

I've recently been doing a ton of research into building my own little system for pop-up parties with my friends. From what I've found, I'm thinking of starting with two SKRAMs and one JMOD top. I'm hoping to get everything built, and to get everything I need to power it all, for about $6-8k.

I'm confident in my woodworking, and I have access to a university lab with a CNC machine and an extremely nice 3D printer, so I figured this would be the best way to get everything just right. Can a CNC and 3d printer pretty much get this whole project ready to assemble?

This is my first build, but I really don't want to spend a bunch of money on a smaller system and end up underwhelmed. I know this is ambitious for a first build, but is it feasible? Any advice on additions to the system would be greatly appreciated. I just wanted some input before diving into a project this big.

We put on yearly outdoor parties for around 200 people and want to build our own rig. A budget of up to £11k needs to cover not only the stack but amps, dsp, cables etc. We play breakbeat hardcore and jungle.

Current, ill-informed thinking is:

6 Cubo subs 18 inch
3 Cubo kicks 15 inch
1 JMOD

Knock off Chinese amps

What would you choose for cabs and amps?

Something that doesn't seem to get talked about that much here. For obvious reasons, mostly the focus is on the main systems.

My tops are Clair R4-IIIs, 3 way + 4 x Martin WSX. 10 channels so far, DSP to amps is Dante, lots of spare in/out channels (at the DSP, not the amps) there both analog and digital if/as needed. Mostly prog/trance/hard.
Working out the booth set up now. @heavywomblesoundsystem

I'm looking at Meyer UPA-1C cabs. Great boxes, but bi-amped means more channels and another amp, then a sub means another channel and another amp... Active starts looking attractive, though it's not usually my thing.

Tops and sub? Active or passive?

Sub in the booth, or rely on spill from the mains?

Do you delay align the booth to the mains, or leave undelayed?

Fed from the mixer's booth out, or a separate output from the system DSP?

Level control: how do you keep it sane, who owns it? DJ trims to your ceilings? Booth levels follow master or independent? Limit the booth boxes (stop creep where the booth becomes louder than the room....I'm sure there are many war stories to be told there)?

Would love to see what works and what others are doing re your monitor set up.

Hey everyone,

I’m planning to build my first DIY sound system for techno events, both indoors and outdoors. I’m still learning and don’t have much experience with sound system design yet.
I’m currently looking at these three speaker designs:

SKRAM 1x21 subwoofer
CUBO Kick 15
Paraflex C-3DKT 1x12

Do these three designs work well together as a system? Would this combination make sense for techno, especially for both indoor and outdoor events?

Since this is my first project, I’d really appreciate any advice or feedback. I’m especially interested in whether the combination is well balanced, how they could be crossed over, and if you would change or replace any of the designs.
Any help or advice is greatly appreciated!
Thanks!

I recently bought a pair of JBL PRX912s and have already used them for several live band gigs. They can get pretty loud and I’m generally happy with their output, but I keep feeling like the bass and low-midrange are somehow “stuck inside the cabinet” and don’t project the way I expected.
I’m running the PRX912s with a 100 Hz crossover, paired with two EV EKX-18SP subwoofers, also crossed at 100 Hz.

My main issue is that I’m missing that “punch in the chest” / physical impact that I expect from a good pair of tops. The subs sound good, but the tops themselves seem to lack that impact in the upper-bass/low-mid area. It almost feels like there’s a lot of energy around the low-mids, but it doesn’t translate into projection or physical punch.

Before the PRX912s, I used JBL EON615s, and surprisingly, I feel like the EON615s had more of that low-mid punch and projection, even though they are an older and supposedly lower-tier speaker.
One thing I noticed is that the PRX912 cabinet is made of a much stiffer/thicker-feeling plastic than the EON615. It almost feels closer to a wooden cabinet in terms of rigidity. I don’t know if that has any meaningful effect on the acoustic design or if I’m just imagining it.
I’ve already experimented with crossover points and EQ, but I still have this feeling that the low-midrange is somehow “trapped” in the box.

So, for those who have experience with the PRX912:
Is this characteristic normal for the PRX912?
Do you also feel that the low-midrange lacks projection or punch?
Could this be related to the cabinet design?
Would changing the crossover point help?
Could I be dealing with some kind of phase/cancellation issue between the PRX912 and the EKX18SP?
Or is this simply the way the PRX912 is voiced?
I’d really appreciate input from anyone who has used these speakers extensively, especially alongside subwoofers.
I’m not looking for more SPL — I’m specifically looking for more low-mid punch, projection and that physical “hit” from the tops.
Thanks!

Just about to start my first project. Been doing other things my whole life. I'm going to build a Soundsystem for jungle and drum n bass. What should I read watch first to get my head into it? I know a bit about frequencies as I used to produce apart from that I know nothing technically. Please help.
