REL T/5x – 8" Powered Subwoofer

REL Serie T/x: T/5x – 8" Powered Subwoofer

No model in REL’s long history has sold more units nor engendered more affection than the T/5. Here reimagined in a modern, elegant, new form factor, T/5x’s mission remains the same: make remarkable bass far beyond its modest size, do so in a way that complements every interior’s style, and eliminate all visual distraction. Perfect for small and medium rooms, T/5x seats perfectly into any décor. Floor-firing is part of its secret; bass energy strikes the floor and spreads uniformly throughout the space, making it perform like a larger model. For those picky about style, the hidden bonus is that this design eliminates even the grille, rendering it the purest of forms.

Highlights & Key Technologies

Designed for Elegance
No model in REL’s long history has sold more units nor engendered more affection than the T/5. Reimagined in a modern, elegant, new form factor, T/5x makes remarkable bass far beyond its modest size, complementing every interior’s style while eliminating all visual distraction. Perfect for small and medium rooms, it seats perfectly into any décor. Floor-firing is part of its secret: bass energy strikes the floor and spreads uniformly throughout the space, making it perform like a larger model. For those picky about style, this design eliminates even the grille, rendering it the purest of forms.

Tried and True Amplifiers
REL has retained its signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership, and with some 200,000 and counting of this range leading long, happy lives, Serie T/x owners can feel certain of REL’s standard-setting reliability. The 125-watt amplifier uses massive power supplies, new driver mosfets that open up performance and transparency, and new methods for securing the toroidal transformers for better performance and superior reliability. (Standby Mode switch is only included on 220V units.)

Uncompressed Wireless Connectivity
REL has developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry, never relying upon digital compression as it results in thin, lifeless sound. Instead, REL has perfected an optional Arrow Wireless system so fast and dynamic that REL is comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel is connected hardwired with cable.

REL Sub-Bass System Design & Connectivity
REL products are not traditional subwoofers, but true Sub-Bass Systems, designed to augment the performance of full-range speaker systems to provide, in certain cases, linear response below 15 Hz. To increase versatility of connection, the Serie T/x models have three separate inputs: a High Level input via Neutrik SpeakOn, a .1/LFE RCA input, and a Low Level RCA input, facilitating use with both two-channel stereo systems and AV surround sound systems. The High Level, unbalanced, dual-channel input accepts the stereo signals from the speaker terminals of your receiver, integrated amplifier, or basic amplifier, ensuring the subwoofer receives exactly the same signal as the main speakers so that the character of the bass from the main system is carried forward into the Sub-Bass System. Combined with REL’s Natural RollOff circuitry, this ensures superior integration with the main system. The amplifier’s input impedance is 150,000 ohms, in effect producing no additional load on the rest of the system, and internal circuitry allows connection to many Class D (digital) amplifiers. High Level and .1/LFE inputs can be used simultaneously; the .1/LFE input bypasses the Natural RollOff crossover and passes the low-level signal through only the required 120 Hz fourth-order filter.

Set-Safe Overload Protection
All REL Sub-Bass Systems are designed as true sub bass speakers, reproducing exceptionally deep notes that are felt as well as heard at whatever volume level is set. If set too high, no damage should result because the built-in electronics limit cone movement. This electronic control, called Set-Safe, constantly and instantaneously monitors the output from the power amplifier and is totally transparent in operation until required, detecting the point of incipient clipping and gently soft-clipping the waveform to ensure actual clipping does not occur. A thermal overload device is also fitted; if the unit is deliberately over-driven, it senses the temperature rise and cuts the output, with a recovery time of approximately five minutes.
