REL S2 Subwoofer
REL S2 Series S Subwoofer. Rel S2 is a 250 watt front-firing active subwoofer with down-firing passive radiator and Next Gen II Class D Amplification. The Rel S2 incorporates Longbow wireless receiver technology that uses no digital compression, giving a performance that rivals competitors’ hard-wired models, REL claims. The wireless receiver is built in as standard, wireless capability is achieved via the optional matching Longbow transmitter which has a range of 15 metres.
The Series S2 uses long-throw bass engines that are said to be super lightweight for speed and slam. Superalloy drivers feature a seamless one-piece aerospace grade” T-6063 alloy cone structure. Additional cabinet bracing throughout the range delivers quieter, more dynamic bass. Whilst S/2 may be the least expensive, most compact chassis in the S range, it would be a mistake to think of it as anything but a true thoroughbred. Fast, tuneful, fun and exceptionally dynamic, S/2 permits those with limited space or compact speakers to enjoy the benefits of Serie S performance. S/2 offers a powerful 250W NextGen Class D amplifier with a fast, lightweight driver and matching passive in a carefully damped cabinet to produce bass that is quite extraordinary for such a modestly-sized enclosure. S/2’s driver receives a new purpose-designed anodized aluminium dust cap.
This both stiffens the cone structure, resulting in improved transient response (snap and attack) while lowering the moving mass some 15%. Careful tuning of this unit to cabinet volume and the new matching down firing passive driver results in outstanding performance for a model of this size and price. Powerful, fast and tuneful is the S/2. Beyond the drivers, the performance of a REL is determined by the input filters and amplifiers.
REL S/2 uses a simple filter-type that is very fast-about 8 milliseconds in group delay to get through to our driver. This speed and carefully sorted filters allows for seamless blending of RELs with the main speakers. S/2’s power amplifier is a powerful NextGen2 250W digital amplifier. This design has proven exceptionally reliable and very fast with deep, extended lows-it provides a perfect mate to its driver
