I have been living with my Maelstrom in a sealed 22" cube and like it. So far, it performs very well as far as I can tell. I have yet to finish the enclosure (veneer, etc) and have come to conclusion that cosmetically, the enclosure would look better if I had a downward firing driver. It is currently a front firing driver configuration. The enclosure could be up to 30" tall. I am using a 250 watt plate amp. I primarily use it for HT and like the hard hitting bass. Should I keep the 22" square and just add another 8" to the height or would I better off with a bigger or ported (or bigger and ported) enclosure? Will any of these changes give me "better bass" or a better performing subwoofer? Should I keep a 22" cube? Any comments or specific recomendations are appreciated. Thanks.
