Fully active 2 way soundbar with MFB woofer

[wankel4486]

Hello all,

I would like to share the building result of my fully active 2 way soundbar made for my son. It is based on basic miniDSP 2x4, Wondom class D amplifiers, Dayton Audio PS95 wide range speakers and motion feedback old speakers Philips AD7066/W4 MFB.

The result is pretty impressive for the size and the sound is quite clear. I think I can make some improvements regarding filtering but it is already good !

Inputs are : analog (from miniDSP board), USB (miniStreamer through SPDIF), Bluetooth (TinySine through SPDIF), SPDIF coax and two SPDIF Toslink.

For those interesting for the details of AD7066 MFB tuning, you can see the posts there : https://www.diyaudio.com/community/...g-piratelogic-electronics.336070/post-7149260

Some details of the building :

After some few hours of work, one woofer has begun to make some strange noises. It was the spider which was unglued on the peripheral, center domes was not so well glued also. So I have unglued totally the domes and reinforce the spider. I take advantage also to treat the paper cone. It is not a well light work but it makes the job and seems robust now ! 🙂
