I have one, but it's been sitting in a bin for a few years because I just haven't gotten around to getting REW working.  I think I have the 2 x 4 balanced.  Right now I can't even find my measurement Mic. LOL

Let's keep each other in the loop with this - I'm cleaning out my spare bedroom to paint and turn into a tiny audio room - if I find my Measurement Mic while cleaning, I'll catch up to you and compare notes.

Originally my goal was to just use it to crossover and EQ multiple subs for my HT and possibly my main two channel setup...but the new Crown amp with built in crossover, and especially the iNuke amps with both Crossover and PEQ have made is so simple to do 80% of what the MiniDSP does.

That said, I still want this tool in my arsenal, plus I want to get REW working so I can better tune my room treatments.

So yeah, lets keep this thread going!?

finally got around to making the REW and miniDSP work to integrate my subs and do some basic XO's and PEQ'ing!  little bit of a learning curve to get all this sh$t to work, but quite fun to play with once you do.

running CSP3 > miniDSP 2x4hd > cary amp (full range) and gallo amp (subs).

sounds pretty damn nice for first go at it!

another cool thing is i was able to put in a highpass filter on my sub output (20hz) and this eliminated all my subsonic rumble with playing my tt.

i've tried several filters that didn't work... this did.

and after listening for several days now i don't notice any neg sound quality from this unit either.

still playing and learning...
