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 aluminum dustcap. 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 downfiring 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 input filters and amplifiers determine the performance of a REL. 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.
