Here's the modeled response of the subwoofer, purple is sealed, red is ported, green is with passive radiators. The response of the ported enclosure is phenomenal but the ports are too long to fit in the box (or too small to not chuff). The PR versi…

Hey I'm not confused. I'm inspired! I had another breakthrough today. I expect I'll run out of great ideas soon. Almost ready to press the order button from Madisound and Parts Express.

I thought you didn't use one Graham? Don't you use the NAD? I don't have a standalone DAC any more. I have DACs of course but they're all in something else - Bluray player, AVR, digital crossover, USB soundcard, USB headphone amp. There's no "DAC…
