REL Acoustics R-Series represents the perfect intersection of style, performance, and size. R-Series is intended to provide its owner with a high performance platform that outperforms the competition, yet provides a level of fit, finish and thoughtfulness long absent from the category.
Details, details! It has been said that “God lives in the details”; if that is so then the engineers at REL should consider themselves in good standing. Consider the previously challenging detail of adjusting performance parameters of a sub bass unit. On most competitors’ models, this requires bending over the unit whilst attempting to read the labels on the rear panel upside down! In contrast, the exquisitely crafted control box –sited just below the main body of the R– allows for easy adjustment. Simply remove the thick frosted safety glass security panel (a full 8mm thick), make a few simple adjustments and you’re done.
No phony computers! No fussing about with a microphone and alleged optimization programs that attempt to crudely approximate real world performance for REL. We offer simple, finely calibrated instrumentation-grade controls that make intuitive sense and are easy to operate. Need a higher volume level? We suggest turning up the control cleverly labeled “Hi-Lo Level”. Crossed over just a tad too high for your tastes? Turn down the control labeled “Crossover”. It really is that simple. Many owners report that it took longer to extract the unit from its excellent packing than to set-up their REL.
Power with Control
R-Series represents our first use of digital amplifiers; REL having determined that until recently Class-D amps did not offer sufficient control to meet our 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.

The all-new T-Series™, from REL, delivers exceptional low bass performance, backed by rugged build quality and the 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 boldly curved 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 capable of supplying effortless, extensional very low bass to underpin high quality audio systems. Although they are offered at prices that compare favorably with competitors’ offerings that often emphasize one aspect over another (output at the expense of quality, or extension at the expense of size), we believe the T-Series offers the best balance of musical and design virtues currently available at this price.
Features:
Neutrik Speakon™ high-level input for direct connection to amplifier.
All connections and control functions are located on rear panel.
Over current, over temperature and under voltage protection.
Enclosure Type: Closed box with heavy-duty 8” ULT active driver and 10” ULT passive radiator
Variable Crossover: 30-120 Hz
Input Connectors: RCA low level input, .1/LFE input with separate volume control
