Hi MeanGene and Spiker,

As a proud owner of a Adire Deava which is a sealed system and uses the 15" Tempest woofer and the DT 300 plate amp in a 22" cube, I love it. and would not look for anything else unless it was a second one for stereo subs. I got mine built as the price was so reasonably ($599)I could not see any reasons to uilt it myself. Great people to do business with
