I have been enjoying my 4Pi's over the past year, and think that it might be time to complement them with a subwoofer.My 4Pi's are ruffly 6.5 cu.ft., with PSD2002 and Delta Pro 15s tuned I think to 42Hz.
I don't have time to build a subwoofer so I was thinking about a commercial unit.
Would I adjust the port length of my 4Pi - and tune it to a higher frequency - perhaps 150Hz (is this possible). Or do I modify the crossover so the cutoff for the Delta Pro is higher?
