Hi Guys

Thanks for your input. I messed up and forgot the currency was in USD so 2x 500s puts me over budget.

That's ok. I think deep down I really wanted to go DIY anyway.

FWIW, the room is a rectangle 21' long. The speakers back onto a 15' wall. The room is tight when the door is closed. The blinds move when I open the door.

We have a NAD T777 as the processor and it uses Dirac to tune the system with a bunch of measurements. It is pretty flexible. I'm probably OK with a DIY sub setup tuning wise as long as I do my research and go with a proven design.

Thanks again for your time!
