It's basically a minidsp & minidigi with two pcm1794 dacs connected by I2S. Also included is a pcb for remote controlled switching 4 digital and 2 analog inputs and volume control. Volume can also be controlled by a rotary encoder. It displays the info on a vfd display.
Wow, that's really nice work knuisje!

Its a pair of tri-amped speakers. used on my front channels(and stereo of course)

tweeter: SEAS 27TDFC with 75uf film capacitor for safety (in case i make a mistake programming)
mid/bass: SEAS ER18RNX
woofer: CSS SDX10

tweeters and mid/bass powered by emotiva upa-500
woofers powered by emotiva upa-200

miniDSP 4x10(2x8 plugin)

I am really happy with this. it sounds fantastic, very clear, goes down as low as i can hear, and i can make any changes i like without buying new crossover bits.

other people have asked me if the emotivas should be stacked. here they are after being on with the TV on for a few hours and then loud music for a couple of hours.

not bad at all 28.4c is the hottest thing on the picture, and i still haven't put feet on the miniDSP to get it off the vents of the top emotiva.

a cool trick, if you do something like this, and keep your old center and rear channel powered by a reciever, is to adjust the PEQ on the midrange to be wrong in a similar way to your old speakers, and use that miniDSP preset when watching things with surround. it makes the miniDSP powered speakers sound close enough to the old ones that there is no strangeness.

i have:
preset 1: music. everything full flat and REQwizzed as best possible for my room. lots of bass extention

preset 2: same as above but "neighbors home" bass is reduced and no "linkwitz" boost below woofer resonance.

preset 3: all out but with midbass altered to sound more like the little polks i have for surround speakers

preset 4: same as above but with "neighbor home" on the bass.

For some reason, no one's posted anything here for some time, and I didn't know this thread existed, so I never posted my speaker project.

I built the Darbari -- the enclosures were done in 2013, the measurements and the crossover were done in Sep 2014.

I used the MiniDSP 4x10HD, feeding six analog outputs to a Marantz AV receiver in 7-channel mode.

Lots more photos on my pages including a lot of construction details.
