REL Acoustics is a British firm that specializes in subwoofer ("sub bass") systems. The model T3 is a sealed, passive radiator subwoofer system. Because it is not ported and relatively compact, it is well suited to smaller rooms since it is faster than ported (larger) models. For a subwoofer of this size it has exceptionally deep and articulated bass response.
The T3 displays a classic feature of all REL subwoofers: independent volume control for both the main and LFE inputs. REL recommends that you hook up the T3 using the high-level inputs on the back of the sub (connected to the same speaker terminals on the receiver or power amp that the main speakers are using) using the supplied Neutrik Speakon cable (10 m or 30 ft long). This way the subwoofer accepts the identical signal as the main speakers. The input impedance of the sub is relatively high (150K ohms) so such a connection does not put an additional load on your amplifer. If you have an LFE output on the back of your receiver/amp, you can use the LFE input on the back of the T3.
A feature unique to the REL T-series subwoofers is a downward-firing active woofer matched with a front-mounted passive radiator. The T3 has two 8-inch units in conjunction with a 150-watt Class AB amplifier.
REL recommends room corner placement of the T3 along the same wall as the front speakers. The front-mounted passive radiator provides greater output and textural detail. Because of the passive radiator's long-throw nature, the front grille is rounded outward. The front grille along with the rectangular rails on the left and right sides of the cabinet, gives the subs a look that is both modern and retro. The subwoofer comes with neoprene pads for placement on a wood floor but accommodates spikes for placement on carpet.
