The T-Series, from REL, is intended to deliver the exceptional low bass performance, rugged build quality and attractive styling of our classic offerings at more affordable prices.

Style: The design of T-Series is guided by its high performance goals. The perimeter rails that define and support the unit are necessary to provide sufficient elevation to allow proper release of the low bass pressure wave. The bold hemispherical dome of the grille is necessitated by the ultra long throw (ULT™) driver’s travel. Quality abounds, such as the polished T-304 stainless steel bolts employed. Such attention to detail is what has made the REL name synonymous with quality.

Performance: Simply put, we firmly believe that REL Sub-Bass Systems should be matched to the performance capabilities of the system and to the room volume in which the system will be performing. The three model offering allows a broad range of main speaker system matching. Consult your REL Specialist for recommendations.

Value: These are genuine REL Sub-Bass Systems intended to supply effortless, extensional very low bass to underpin high quality audio systems. Although they are offered at prices that compare quite favorably with competitors’ offerings that often emphasize one aspect over another (output at the expense of quality, or extension at the expense of size), the T-Series is intended to offer the best balance of musical and design virtues.

Power with Control
R-Series represents REL's first use of digital amplifiers; having determined that until recently Class-D amps did not offer sufficient control to meet their standards. However, recent advances in the state of the amplifier art have resulted in a range of amplifiers that demonstrate excellent speed and control, especially in the low bass. When partnered with new drivers that are higher in performance, yet lighter in weight than their predecessors, the result is a new level of performance for the category.

Unique R-Series Features
REL R-Series are not traditional subwoofers, but rather true sub-bass systems. The R-Series is designed to augment the performance of “full range” speaker systems and to provide linear response down to below 20Hz. Properly set-up and positioned, they will take advantage of physics and room acoustics to provide deep pressurization as no other subwoofer can. Unique to the REL are its connectivity options. For two-channel audio systems a high-level connection, using the enclosed cable with the Neutrik Speakon connector, is always the first choice. By connecting to the amplifier’s speaker outputs the sonic signature of the entire amplification chain is folded into the signal for the sub, thereby keeping timing and timbre cues consistent. Additionally, a low-level connection using RCA inputs is always an option, should high-level connection not be possible. In a surround system where both high-level and low-level connection is used, the REL R-Series provides individual inputs and gain control for both the Neutrik high level and .1/LFE input allowing accurate signal blend and balance.

All R-Series models feature a front mounted control box where gain, crossover and phase adjustment reside. The location of these controls allow for easy access when performing set-up and a glass security panel can be affixed to prevent tampering. Additionally, this box can be removed from the enclosure along with the feet to effectively reduce the enclosure’s size. This is most useful in a custom installation situation.

With BRITANNIA, an entirely new generation of high-end music and film sound devotees are poised to revel in the fruits of REL’s labors. These offerings are superbly crafted to perform dual roles in both the most sophisticated music or film sound systems with equal facility.

The combination of an ultra-powerful new range of bass-engines, mounted forward firing, and with a patented twin-chamber exhaust, venting out the bottom produce truly prodigious low frequency output with startling speed.

Quality isn’t everything; it’s the only thing. All Britannia Series feature 24 crossover frequencies from 22-96Hz, using precision trimmed circuits. REL’s unique design permits operation of both high-level support of main speakers and .1 channel from one B1-something no other manufacturer offers. Massive power supplies and outstanding build quality are the cornerstones of REL’s reputation.

Reference class sub-bass system designed for use with very high quality stereo and multi-channel audio systems in larger rooms.
