EAGLES, by that criteria would go for either the Hsu VTF15h or Epik Empire, although the Hsu is $17 over your budget after shipping. If you have an amp, check out the Chase SS-18.2P
, I am sure that would win a SPL war against the Hsu or Epik. For sheer 25+ hz output, the Elemental Designs A5-350 would be a good choice, and it's only $800 shipped. The Hsu VTF3 and Outlaw LFM-1 EX would also be great choices, especially when run in maximum output mode. In fact, you might as well save some money and go with the Outlaw LFM-1 Plus or Hsu VTF2, since you are not concerned with stuff below 25 hz. Stretch your budget a bit and you could buy two VTF2s or LFM-1 Pluses, that would make for a very formidable bass system, with all the advantages that come with multiple sub setups.
