Definitive Technology bp2002 Tower bipolar speakers with built in subwoofers and amplifiers. (Matched pair) $650

I’m selling my favorite speakers. These are the best speakers you could buy under $3,000. They are in excellent condition and sound amazing. Come try them out. If you want to understand the Definitive Technology BP2002TL loudspeakers, look behind them. Separate terminals, linked by gold jumpers, feed the tweeters, the bass/midrange speakers, and the 12-inch subwoofer. Two line-level inputs also feed the sub's built-in amplifier--one for full-range signals and one for the LFE signal found in surround systems. The manual devotes six and a half pages to the many possible connection combinations. And once you've decided how best to wire up these monsters, they produce truly awesome sound.

Also on the back but hidden by the grille cloth is a rear-facing array consisting of a tweeter between two bass/midrange drivers, duplicates of the setup on the front. This driver arrangement, called a D'Appolito array, minimizes floor and ceiling bounce by providing broad horizontal dispersion while limiting vertical dispersion. Bipolar Isn't Just a Mental Disorder Like most Definitive Technology speakers, the BP2002TLs are bipolar, with their front and rear drivers in phase; the rear drivers push outward and pull inward at the same time as the front ones. This differs from dipole speakers, which have out-of-phase front and back waves. The bipolar design gives speakers a fatter, almost omnidirectional sound dispertion, whereas dipoles project sound in a figure-eight pattern--all to the front and back and nothing to the sides.
