You can make the cabinet anything from about 2.5 cubic feet to 5 cubic feet, and have tuning anywhere from about 38Hz to maybe 50Hz, and still have an acceptable speaker.

I know that you recommend PiAligned cabinets, but how would a 2226H in a 4.5-5 cu.ft. box tuned to 40-42Hz perform compared to a 4 Pi with the Delta 15?

By the way, my Beymas drivers sounds real nice. I still haven't changed the filter from the MD2001, so I reckon they'll get even better. I've also bought a set of Oris horns. I can't afford the Lowther drivers for these yet, so I've decided to order a pair of Beta 8CX instead. My 4Pi will be used for bass.
