You guys have to check out the Adire Tumult.I currently use two,each in a 2.5 cu.ft. cabinet.Since the F3 is about 27hz in that small of a cabinet I am going to buy two more and run a Marchand bassis to reshape the curve flat down to about F3 of 16hz.850 watt mono adcoms on each and .....oh boy I gotta go to bed.
