So heres my recommendation. Consider not getting an 80prs. I have one, its great but it has some very serious tuning draw backs and its interface is kinda..unintuitive.
Instead get a C-DSP. It has a full 6 band parametric PER output. So 6 bands PEQ per speaker and then another 6 PEQ over your entire l/r input. plus time alignment and crossover control. It has everything and more that the 80prs has and all around the same price. There is also a thread on
DIYMA that shows you how to pretty much auto tune your system with the C-DSP and a program called REW
The only thing you need to worry about is how you get your source signal there. If you use an android based phone, you can get a 20$ adapter that turns your phone usb to a SPDIF output. its SUPERIOR sound quality and no chance of noise in your system.
