REL Tzero MKIII Subwoofer

Tzero. Not lesser, just smaller. The MKIII is everything REL, and ideal for studios, studies, nooks, and desktop systems

"Tzero is in many ways the most difficult design we have ever executed because never before have we delivered so much for so little."--REL Acoustics

One of the reasons we love REL, and sell so much REL, is that this company does not mess around. Not even at the entry-level--take that quote from them, above. Just like Serie T, the Tzero comes with five coats of high-gloss lacquer, NextGen Class-D amps, a high-level input, and a separate .1/LFE with its own volume (double-duty sub!).

The MKIII uses a new aluminum-cone driver and this 6.5" unit puts out REL's legendary textured, articulate, fast, deep bass. Real-life bass. Do you have a medium or larger room (over 200 sq ft)? Get something from up the line. Tzero is for those cozy systems that don't need to pressurize large spaces.
