REL Acoustics Serie T 6.5-Inch Powered Subwoofer in Gloss White Lacquer (Each) - TZERO MKIII WHITE

REL Acoustics TZERO MKIII WHITE Serie T 6.5-Inch Powered Subwoofer in Gloss White Lacquer (Each)

The REL Acoustics TZERO MKIII WHITE Serie T compact powered subwoofer combines a sealed cabinet, a down-firing 6.5 in aluminum-cone driver and a built-in 100-watt RMS Class D amplifier in Gloss White Lacquer. Low-frequency extension is 37 Hz at -6 dB in-room, while high-level Neutrik Speakon, low-level RCA and dedicated LFE RCA inputs support stereo and AV connections. Independent LFE gain lets music and film settings coexist, making this single-subwoofer configuration a fit for small bookshelf speakers, desktop audio and compact 2.1 television systems.

Key Features

Five-Coat Gloss White Lacquer

The white finish is built up with five lacquer coats, hand sanding between coats and final polishing. Machined, bead-blasted, clear-anodized billet-aluminum feet and badging carry the detailing beyond the cabinet surface. Inside, 3/4 in MDF, glued joints and bracing form the sealed acoustic-suspension enclosure, reflecting a design focused on carefully controlled cabinet behavior.

6.5 in Aluminum Driver and 37 Hz Extension

The long-throw driver combines an aluminum cone with a paper damping layer behind it and a steel chassis. Developed around compact-system listening, this construction is intended to preserve agility while adding impact to bass guitar and kick drum. Its specified in-room lower response reaches 37 Hz at -6 dB, setting a concrete expectation for bass extension rather than promising extreme cinema output.

100 Watts RMS of Built-In Class D Power

The driver has its own amplifier, so it does not require a separate external power amplifier. Efficient, cool-running Class D operation suits the miniature enclosure, while standby circuitry responds to low-level signals. Fully Electronic Set Safe protection addresses DC faults and output shorts.

High-Level, Low-Level and Dedicated LFE Connections

Use the Neutrik Speakon high-level connection for the stereo path, or the single low-level RCA input for a line-level signal. The dedicated LFE RCA socket allows a film-effects feed alongside the music connection. A 32 ft Neutrik Speakon cable is included for wired high-level setup; RCA interconnects are not included.

30-120 Hz Crossover and Independent LFE Gain

Separate level and crossover controls let you adjust how the subwoofer joins your compact speakers. The crossover spans 30-120 Hz, and a phase switch offers 0 or 180 degrees for system matching. Set the LFE channel's gain independently instead of repeatedly changing the music settings when switching to a film.

Optional HT-Air MKII Wireless

Add the separately sold HT-Air MKII transmitter/receiver system to carry low-level or LFE audio wirelessly. This option does not carry the high-level connection, which remains wired. The subwoofer still needs mains power through its included 6 ft AC power cord; wireless audio does not eliminate that connection.

Who It Is For

Scaled for small-space listening, this subwoofer is intended to complete computer-audio systems, small bookshelf speakers and compact 2.1 TV setups. Ideal-room guidance is up to 150 square feet, with under-desk placement, apartments and small libraries among the intended settings. This configuration includes one subwoofer; stereo-pair or dual-sub use requires another unit. Vertical line-array stacking is not supported.
