I have heard things on a tune i made in 1999 which i have never heard despite listening on a lot of systems. a MIDI note is stuck at the beginning of the tune.

Looks great!! How is the SDX10 loaded? Wish I had time to learn how to use the miniDSP. They showed some new stuff at CES in January but so far the samples promised have not been released.

The SDX10 are in sealed enclosures the recommended size. I have a bit of a boost below the resonant frequency, and the bass is amazing. It goes as deep or deeper than the sub I had before but sounds much more integrated with the mids and tweeters. I have tried a few different crossover frequencies, and I have it at 147hz with a 24db FIR filter, so far that's what sounds best to me, but there are a lot of combinations to try.

The miniDSP is really easy to use and nice because you don't have to buy expensive capacitors and inductors every time you want to try different EQ or crossover or add some EQ. You program it via USB from a computer, but the computer does not need to be on for it to work. Some people might be too good for its DAC though I haven't really noticed it as sounding like anything, and it's certainly better than the one on any motherboard.

I'm going to redo my REQ because I moved some furniture. Ill post the graph after that.
