My pro fours are still in the shop and I am not sure they will have access to the livingroom (SWMO's opinion). So I am searching for other options. I am able to put a largeish sub (such as Bills T36S) under the (to be homebuild) couch. I have got a pair of 2206. They pialign in 0.73 ft^3 which really is a very small enclosure. Assuming cornerplacement hanging from the ceiling with the tweeter below the woofer, how low can I cross to the sub, hopefully around 60-70 Hz) ?

Wayne Do you still have the Pro 3 plans using the 2206's. If so, I would like a set.

Cheers and take care with the tablesaw.
