Description / REL Tzero MKIII Subwoofer


REL states Tzero MKIII subwoofer is, in many ways, is the most difficult design they have ever executed because never before have they delivered so much for so little. Available in black or white high gloss lacquer as in all Serie T, NextGen Class D amplifiers, our famous High Level Input, plus a separate .1/LFE input stage with its own volume control to get theatre levels and music perfect without racing to adjust or looking for a remote control.

The jewel of the Tzero MKIII subwoofer is the new aluminum-coned driver, a rugged 6.5” unit with exceptional output and low bass extension for its size. While it won’t drive medium or large rooms hard, we make plenty of larger models that handle that task, Tzero MKIII remains a miracle in miniature

Though Tzero MKIII is REL’s entry level, that doesn’t mean it can’t punch far above its weight class. 100 high-current watts from a NextGen Class D amp means it holds its head high and is capable of delivering many years of satisfying performance. We feature the same high-quality input filters, crossovers and limiters as our larger models.  Tzero MKII includes a full REL connectivity suite, fast 8ms delay filter set and our famed High Level Input as well as a separate .1/LFE input with its own level control and a standby circuit that reliably comes alive at very low levels.
