I only have about 5 cubes to work with ported and want something that will have no problem at 32hz so keep that in mind. I have an Orion 2500D for power. Preferably something that sounds decent like an Eclipse Ti Pro, MT, or Atomic....For trade or sale I have a TC-3000 15", 3 MB Quart RWE-304's, LG dvd shelf system, DVD recorder, Emachines computer w/ 17" screen, Corona sign, and if local I have a nice 3 piece slate 8ft pool table w/ black felt.
