By today's standards the EP350/500 size (same box for both) is quite small compared to other companies offerings for ported subs. I know the EP350/500 was quite a bit smaller than the PB12-nsd I had for awhile and compared them to.

There is also the Paradigm DSP series of subs, the 10" version's box is even smaller than the EP350/500 and does a reasonably good job for HT in fairly large rooms, not as good as the 12" Ep series but quite good IMO.
