Operation Manual

Welcome to the REL Family

Thank you for purchasing a REL TZERO Sub-Bass System. The TZERO is the result of a state-of-the-art collaboration

between our American design and engineering team and our British production team.

TZERO is conceived as the most cost effective high end product we know how to build. We have spared none

of the materials and finishing techniques our larger designs are noted for. Many competing products are

clearly the result of cost engineering, however, TZERO is a pure high end product in design and execution.

If, like many, you are surprised and delighted by the quality and “suddenness” of bass as rendered by TZERO,

know that this is the result of a careful, painstaking iterative process of the sort that so rarely makes it into

production at anything like these prices.

Many of the sonic virtues – speed, warmth and slam – embodied in TZERO are the direct result of

mechanical and acoustic advancements. In particular, we have utilized thick slabs of dense, acoustically-

inert MDF, masterfully bonded to create an exceptionally rigid, near-monocoque cabinet. Additionally, the

aluminum feet are milled from solid billet and weigh an incredible amount. We thoroughly tested and

were able to clearly discern the benefit of having a solid, high mass exit path for deleterious vibration;

vibration that would otherwise slow and blur the clarity of bass lines. Make a structure inert and quieter

and more of the music emerges.

A brief word about the styling, fit, and finish. Each TZERO receives nine coats of lacquer, all of which require

hand sanding. The final coat is then turned by hand on a large, industrial rouging wheel using jewelry buffing

compound. Finally, the deep, wet gloss is achieved by hand polishing using micro fiber cloth and expensive

automotive waxes. All exposed bolts used to attach the rear panel to the TZERO cabinet are polished T-304

stainless steel allen head designs. This extra cost is undergone to ensure that even in humid markets RELs

will not oxidize or degrade in appearance. Each badge is milled from solid billet aluminum and is a full

2.5mm thick even though we choose to only reveal 1mm above the surface of the cabinet. Much like the

underlying quality of all RELs, more lies beneath the surface than is evident to the eye.
