Fast, Fun & Powerful
The Compact S/2
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 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

REL’s passive drivers are carefully matched to the active. In the case of S/2, we literally use the same driver as S/2 for a precise match, then tune the resonant frequency a little lower to extend the bass performance downward for a cleaner overall effect.

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.

Reviews

Anyone who thinks of themselves as an audiophile may be more than a little dismayed to see a subwoofer review in these pages, but there’s a lot to be gained from integrating a subwoofer into a two-channel hi-fi system that stretches beyond the reach of the majority of traditional loudspeakers. Subwoofers have come a long way in recent times, and with careful integration including a sub in your setup can have benefits on other elements of the sound aside from just extending its low-range performance.

REL has been at the top of the subwoofer game since the Welsh company first appeared on the scene with models back in the nineties.
