I was put onto the IPR7500 by a well respected guy on a UK forum, but I have a question: What would it give me over my current iNuke 6000DSP?
I run a pair of sealed 15" subs using Fi Q series drivers wired so each sub is 4 ohms, they are different distances from the MLP, so I can't wired them together as one 2ohm sub as I need to add a separate delay to the closer sub. I've run power tests in REW and I believe I'm amp limited at the moment (the Fi Q are rated 1500 watts), plus I may upgrade to Fi SP4 at a later date which are rated to 3000 watts.
