Hi all

This is my first speaker/subwoofer project and I'm excited about the end result! 😁, so this is just me showing of.

I've wanted to add 2 subs to improve the bottom end of my Dynaudio Contour S3.4's for a while, so it was time to do something about it.

Initially I wanted to get 2 SVS SB-2000 pro's. But I already have a big amplifier and a receiver for DSP (Denon x3800h), so I didn't need active subwoofers. I realized that I could get what I wanted for half the price by DIY. A good opportunity for a nice project where a lot of my power tools came to good use.

The goal for the project was simple, build 2 subwoofers for music, which hopefully will be at least as good as a pair of SVS-2000 pros.

I've used a pair of scanspeak revelator 32w units for the project (32w/4878t00).

The cabinets are built with 19mm MDF, double MDF front baffle, with an additional 9mm MDF plate to create a rounded countersink hole for the units. So, a 47mm thick front baffle.

I've been creative with the bracing where I used the 9mm MDF I had. I made a "cross" to support the center of the walls, it also saved a bit space compared to window bracing.

To add weight and resonance damping, I mounted some bitumen plates on the walls as well (3kg extra weight). And then around 450g of polyfill for damping.

This results in 2x18kg heavy cabinets with a volume of 54l, and a Qtc around 0,7.

I'm still waiting for the second driver to be delivered, but so far the first subwoofer is running. It integrates and sounds very well! It could be fun to compare them with the SVS's subwoofers one day.

I like the white satin color, so I might also send my Dynaudios to the painter one day.

A car someone was working on found a nice sound system inside.

Je m'en sépare

2 weeks ago I bouth these speakers for just 20€ and the enclosures are in very good conditions but the speakers aren't.

I'm building a full 3-way system keeping the enclosures and replacing the original speakers for Beyma speakers

- Woofer (Beyma 6P200FE)

- Midrange (Beyma 4FR40)

- Tweeter (Beyma T-2030)

- Crossover (Beyma FD-350)

The original speakers have the midrange with closed basket but the 4FR40 is open basket so I need to make a custom enclosure with PVC for the midrange to separate it from the woofer.

The Beyma 6P200FE it's a bit overkill, massive magnet and 2" voicecoil witch it supports up to 200W AES

The tweeter will be the biggest change, the original tweeters are made of paper and they are cones, the Beyma T-2030 it's aluminium dome tweeter.

The Beyma FD-350 will be another big change, it's 2nd order, the crossover points are 2 KHz and 7 KHz.

Vocal clarity is outstanding. Spent all day getting my polar measurements and designing active crossover in vituix. Room needs acoustic treatment and speaker needs an in room tune. Waiting until I have second speaker built to do so. Enjoy sharing my creations, hope someone will find it interesting.

Help

Hey everyone, looking for some advice 🙏

The wire connector/pin from my subwoofer snapped in half ,one part is still stuck inside the speaker input, and the other half is on the cable .Is this something that can be repaired, or am I better off replacing the connector or the whole unit?If it is fixable, what’s the safest way to get the broken piece out without damaging the sub?Any tips, tools, or similar experiences would really help. Thanks in advance!

Hello everyone

These speakers were rescued from an old cheap stereo system but I kept the enclosures because they are made of good quality wood.

These enclosures are designed for 4" woofers so I decided to install the best woofers that I could, and then the Beyma 4FR40 appeared, 58€ 2 units, full range speaker used as a woofer.

The original tweeter was crappy, paper cone, clipping at 2 KHz, garbage sound... It was not easy to find tweeters that could fit in the tweeter mount but I found a good ones for 35€.

The crossover is the Beyma 2FF2VHF, it was the hardest part to fit inside the enclosure, I had to place it vertically and glue to one of the sides.

When I ended the project, I tested it and surprisingly can beat many speakers arround the market like the Polk Audio S10, T15...

They sound very good, natural midrange, woofer goes down to 50 Hz (very low for the woofer size) and crystal clear highs
