Introducing T-Zero

The REL T-Zero is the result of the collaboration between REL’s American design and engineering team and their British production team. The T-Zero was conceived to be the most cost effective high performance product that REL could possibly build. They have spared none of the materials and finishing techniques that their larger designs are noted for. Many competing products are clearly the result of cost engineering, however, T-Zero is a pure high-end product in design and execution.

Many of the sonic virtues – speed, warmth and slam –embodied in T-Zero are the direct result of mechanical and acoustic advancements. In particular, REL have utilized thick slabs of dense, acoustically inert MDF, masterfully bonded to create an exceptionally rigid, near-monocoque cabinet

creating an inert structure that allows more of the music to emerge. The powerful and efficient Class D amplifier is mated to a down-firing 6.5” long-throw driver capable of launching a surprising amount of room filling bass that belies the T-Zero’s size.

T-Zero enjoys all the connectivity options found on all REL Sub-Bass Systems. For 2-channel systems the High-level connection, using the Neutrik Speakon connector, is preferred because by connecting to the amplifier’s speaker outputs the sonic signature of the entire amplification chain is folded into the REL signal thereby keeping timing and timbre cues consistent.

The REL Connectivity Suite&™ allows for using both high and low input options. The ability to blend and individually control both signals that, for example is useful in a home cinema system where the sub-bass system must reproduce both main speaker and .1/LFE low frequency content. Additionally, connectivity to Class D main power amplifiers cause no problem thanks to REL-D&™, a proprietary circuit that creates the proper grounding environment for most Class D amplifiers.
