While reading other posters questions around complementing a sub woofer with 4 Pi it kind of got me curious so I did a quick and dirty test using an existing JBL sub woofer that I have connected to my Home theater and tapped it into my current 2 channel setup with a Y- RCA cable off one of the channels between my DAC and SET amp.
My JBL sub woofer have a variable cross-over and variable gain so it allowed me to adjust its output to blend with the 4 Pi...
Overall, the sound from the sub was difficult to blend with 4 Pi and in some cases, I noticed the sound from the sub was a little out of sync from 4 Pi.
Question, will the issues mentioned above still be there if I build 3 Pi sub woofer and use Pyle crone cross-over mentioned by Wayne? I'm thinking of re-using one of my decommissioned Eminence Omega speakers when I build the 3 Pi sub.
Thanks

thanks for the links... So starting with two flanking subs it is.
Due to room space constraint, is there a big difference in sound quality between 8, 10, and 12 inch woofers if the the boxes are tuned for the same frequency range?

Where subs are concerned, woofer size shouldn't be considered a qualitative difference, but rather a quantitative difference. Subs are pretty simple systems, and the biggest differences where cone size is concerned are mass and radiator area. Increased mass tends to tune the system for lower frequency and larger radiating area tends to make the system more efficient. But the larger cones also tend to make the box requirement larger too. If you need a physically small box size, and bass extension is desired too, then the cone size will need to be smaller to allow the proper box alignment for a sub.
