Hi,

​I’m looking for some guidance on restoring a pair of vintage Jamo Studio 135 speakers. Unfortunately, the tweeter in one of them (Jamo model 44055) has died. I’ve confirmed it with a multimeter.

​The problem is that I can't find an exact OEM replacement part anywhere. I’m aware that this is a 3-way system, so I know I can't just slap in a random full-range driver or a cheap piezo tweeter.

I also know that the original driver has an inductor attached directly to the magnet, and I understand that I need to transfer this to any new tweeter I install to protect it.

I also did some upgrades in the box.

I am new to DIY audio stuff and I want to make this bag an actual portable Bluetooth speaker. Where do I start? Ideally the speaker itself should have the size 25x10 cm. Any beginner tips?

​

But Stream32 isn't just an MP3 player.

My goal is to turn it into an open-source music ecosystem.

The idea is to combine several things into one platform:

- A portable touchscreen player that you can build yourself

- A desktop application

- A self-hosted music server

- Online music streaming

- Internet radio

- Music synchronization between devices

The current prototype already supports:

- MP3 playback from a TF card

- Album covers

- A touchscreen interface

- Favorites

- Volume control

- Multiple screens (Home, Player, Tracks, Radio, Settings)

- Bluetooth integration

The entire interface is written with TFT_eSPI.

Future plans:

- Streaming similar to Spotify

- Custom radio stations

- Metadata support

- Themes

- Wi-Fi synchronization

- A desktop application

- A custom PCB

- A battery-powered version

- A custom 3D-printed case

The idea is simple:

You shouldn't have to buy the player. You should be able to build it yourself.

I'd like to hear your feedback.

I built a full working Solar PA Music Speaker,

66€ Solarpanel 100watt

0€ old MDF wood

0€ small speakers

10€ Subwoofer

0€ (24€ but for free) class d amp board China 200watt

Works with xt60 plugin and 5-26 Volt

So you could use any dc from 5-26 v

And it works with this solar panel without any accu

About 2 1/2 months ago I posted here about me wanting to build a custom cabinet for my hi-fi gear, for a couple of reasons:

My old cabinet was dated and was falling apart due to the heavy load of the equipment, and it was also an inefficient use of space as I needed more bays for all the different separates in the audio chain.

I also always struggled with access to the back of the equipment to e.g., change interconnects, so another design goal was to have easy access to the back of the equipment.

I therefore designed my cabinet with a 6 inch deep cable chase so interconnects between the units are staying inside the cabinet in the designated cable chase.

Well, the project has of course progressed since then and I'm sharing some photos of the different stages. I had to build custom tools and jigs to help rout dados into the base for the vertical side panels and vertical panels for the shelves, making sure everything had a nice fit for all the solid walnut pieces.

One thing with building cabinets is that precision is key. If you're off by the dimensioning of the various pieces, or routing the dados is off, or things are not aligned exactly 90°, the errors compound and suddenly you find yourself where the pieces may not fit together well.

The walnut pieces were originally raw slabs that were milled to my specified thickness. I then glued them together to get to the panel sizes I needed for the base, the vertical panels, and the shelves.

I have reached the stage now where I have glued together the carcass and I'm about to stain it to its final finish.

The next step is to start working on the top, which will be a live edge river slab, about 2 inches thick and floating, so I can easily remove the top and have easy access to all the equipment and cabling in the cabinet from the top and back.

I love picking speakers off marketplace/craigslist, cleaning them up and flipping some, keeping others. I love audio and have been into the hobby since I was a teenager but have never done any hands-on restoration minus a pair of Bose 901 reform. Before I crack into restoring my beloved Infinitys, I thought I’d try my hand and these Bose 701s I found for a crisp Benjamin.
Unique and Weird is pretty much the only way Bose rolls and these are no exception. I had a passive, series 1 pair of Bose 701s that were a very cool design. And these are their second generation with a similar design- utilizing a 3 way system, midrange firing at the rear wall at an angle with an open baffle cabinet, 3” tweeter and 2.5” stereo targeting tweeter, with a powered 8” woofer on each end. I got these for cheap because the vinyl veneer is peeling.

Plugged them in and was surprised they’re functional for being from 2001. This was the last 3 way speaker Bose ever made and was least loved and I can’t really see why. Following the set up instructions they’re huge fun for classical. They paint a massive picture of the orchestra albeit at times raked a little high in image height. Anyway, I noticed big bass sometimes made the speakers distort. With the help of my clanker friend, Claude, I’ve been diagnosing the amp (it’s a daisy chain so all lives in the left channel). Think you guys could double check his work? Like I said, new to actually working on amps and speakers but understand the general concepts and terms. Any help appreciated!

Hi,

This invention entails a double curved sinusoidal membrane which moves in-plane in the x axis (left to right in schema)

A washi (2gsm) paper epoxy laminate with a targeted weight of < 0.5 gr including around 50 winding in square formation of 44awg wire (around 0.05mm ) . The edges containing in-laminate copper go through a ~ 1mm neodymium gap with a strong field.

It is suspended on a 3d printed trapezoid compliant mechanism similar to the shown image on the right. A 0.4 or 0.2 nozzle will be used to create arced lines that have very little bending friction.

The expectations are that it will sound weird. What I’m hoping for is that some range of the full spectrum is audible. I have designed part of the mold to pre press the humid washi paper. And then brush heated epoxy on is the thinnest way possible.

The membrane is similar to a vocal cord but vibrates coplanar while the curves will move the air.

Zero audio knowledge. Just found out I am missing a connector. I was about to attempt to wire this tonight but hit a roadblock. Can someone please send me the link or exact name of this part? It’s connected to a JL 12W7AE if that helps but I believe the box is custom. Pictures attached.

Last 3 slots available for the end of this month. Book your appointment now to get your system tuned by me. For those of you trusting me with your systems THANK YOU. Everyone starts somewhere. For the trolls and haters, watch me work!! 👀💯👌🏽
