Greetings from Germany
2.1 Active Subwoofer Broadband System, inspired by the DINAS but cheaper
Broadband Omnes Audio BB3.01A
Subwoofer Omnes Audio SW 6.01
Satellites: 3 Liters, bassreflex vented, tuning frequency 80 Hz
Subwoofer: 12,2 Liter bassreflex vented, tuning frequency 37 Hz, f3 -3dB @ 34Hz
Amplifier: Similar to Lepai LP210PA 2x30W + 60W 2.1 Channel Mini Plate Amplifier TPA3118 Subwoofer frequency filter from 30 to 150Hz Satellite filter frequency from 100 Hz
Built-in Bluetooth 5.0 module
Body: birch plywood multiplex 12mm
Top and front: Oak glue wood 18mm
So i posted this in the wrong section, now ive found the right one, this is my first completed bluetooth speaker. Made this for the mrs, she loves it. Enclosure is made from 18mm mdf, clad in aged brass with a satin paint on the baffle. I used the dayton pc83-8 for this build, for such a small driver the bass is rediculous, vented i think these go down to around 55hz, but correct me if im wrong. Either way everyone who has heard this has said they cant believe how good it sounds without a sub so i think it turned out ok
Thankyou, that means a lot coming from someone who makes a lot of good quality speakers. The sides though arent wood, its a folded peice of brass sheet that i aged with an acid and glued onto the mdf enclosure, i make brass bar tops and other fancy metal products in the same way at work as im a welder/fabricator so that gave me the idea. I did have a few meltdowns though trying to paint that mdf front! 😂
I made a 30 cal ammo-can boombox. Really fun to take places and show off 😉
It's pretty solid and sounds very nice for its size. Works of a 3s battery pack and a class d amp board.
Hereby some pictures of my most recent builds:
I used two PS95-8 for desktop speakers and added a TB W5-1138SMF to complete it into 2.1 system. The woofer is still playing in an MDF enclosure, but the PS95's now play in a closed box from beech.
Next was to add the same sub for the desktop speakers at my home-office. What shows to be a good extension for the low-end. The drivers at my desk are Dynaudio 17W75 and Eton 25SD1
Next plan is to rebuild the boxes for the Dynaudio/Eton's. A good inspiration was the two-color wood boxes of the Dinas earlier in this topic. I tried a sample of meranti in beech. This should become nice to look at while working 🙂
A question: Does any of you have some experience with variovents, especially to build them yourself? The 17W75's have a Qts that is a bit on the high side, so a slight improvement would possibly help to polish up the impuls response just bit.

@foxaudio They look really fantastic. Good wood-working job!
I have a question though. You mentioned that the satellites are ported at 80 Hz, yet filtered at 100 Hz. What was the reason that you put the satellites in a ported box?
Thanks for your question, which I probably can not answer directly. My intention was to get the bass of the satellites as low as it can be, so I added a port and it turned out, when I designed the case with WINISD, that 80 Hz would be the best option for those small speakers. And I can say, closing that port with the hand, removes a lot of base response, so I think this port is very useful. As I'm using this in combination with the relatively big woofer, I thought the satellites need to reach down as far as possible. Also I think the crossover in the used amp is not so steep, so starting cutting off at 100Hz still had less than -3dB volume loss at 80 Hz.
I haven't measured those yet and I'm sure these could be optimized. But I'm pretty happy with the build and the sound.
I have them in my sleeping room attached to an Arylic S10 preamp which allows me to connect via BT, stream Spotify and so on. I have attached a fire TV Stick to that preamp and it works great for watching Youtube and listening to Music via Spotify.
I'm looking forward building a new set for my workshop with the amp Toid just reviewed, where you could change the crossover frequency via the DSP.
