This is a speaker enclosure for the Tang Band W3-881SJF. These are fantastic along with the 3.5" micro-sub (enclosure Thing and info here) for near-field use.
These drivers alone are very anemic on the low end, so something to supplement them below ~150 Hz (I believe - I've got to track down my frequency response measurements) is necessary in my view. See my other projects for 'fuller' range speakers.
