Purchased this to tune my SVS Ultra but with the other projects I have going I'm not going to get around to it for a while. It has been hooked up but that's about the extent of it. Includes the following: 1) Behringer DSP1124p EQ 2) M-Audio USB Midisport Uno MIDI Interface w/ disc 3) Radio Shack digital DB meter 4) Sound Blaster Live 24 bit external sound card w/ disc A whole crap load of instructions that I have printed off to make tuning your sub as painless as possible. I can even include the REW program if needed. 175.00 shipped and pp'd I can provide plenty of feedback should you need it.
