I think you make some excellent points tomtuttle. A different form factor should be considered here that is different from the VP150 and VP180. The VP100 has a nice small footprint but is limited to smaller/medium rooms so anyone with a seating position that is far away the VP100 is not ideal. Anyone looking to trade up for better performance or a bigger room and if there is a 4th centre (which is a lot of centres btw \:\) ) a cabinet that is not as long as the VP150 but with a trade off in added height would be ideal. I would think this would give an individual as much choice as possible when considering what centre option one wants.

I don't think there is a problem with rear porting either, dual front ports could be a consideration as well.
