Nice shots. I'm going to go with either the 1 or 2 Pi bass reflex. The towers would be nice, but I just don't have the skill (or tools) to do them justice. I'm going to have a local cabinet shop cut the wood for me, and if the price is right have them do the assembly.
I'm really interested in building the Pi speakers, so I can see how my Cayin TA-30 sounds in SE mode. Since I've had the Cayin, I have only run it in PP (35W) with my Maggies......Colin
