i was thinking of building the pi one as a cornerhorn - i.e. with the woofer mounted on the back (just to augment the bass, although i've never heard the pi one and don't really know if it's required, i know i like the bass on my pi two towers)

anyway, any reason why the rear mounted woofer wouldn't be a good idea? i'd follow the rest of the design as is

also, if the speaker were to be mounted approx. 5-6 off the ground in the corner, should the tweeter be mounted to point downwards?

thanks
