Klipsch KSW-10

Klipsch's Synergy Sub-10 is powerful and musical, and that's not something you always find in midpriced subwoofers.

Klipsch has developed a winning formula for its best-selling line of subwoofers: build in lots of power, design superb woofers, and make sure that the subs can fill even large rooms with soul-satisfying deep bass. That last criterion is a brave move in a market that favors ever smaller "lifestyle" speakers and subs -- and no matter how you look at it, the Klipsch KSW-10 is far from petite. This bad boy measures 394mm high, 343mm wide, and 368mm deep, and it tips the scales at 13.2 kg. The KSW-10's textured black vinyl finish is highlighted by titanium trim pieces, but the overall look is pretty bland.

The sub's 10-inch, down-firing driver is coupled to a highly efficient 200-watt amplifier, which is said to provide 420 watts of dynamic power. It's worth noting that Klipsch's power ratings conform to the more rigorous FTC rating standards, so -- unlike the wildly optimistic wattage ratings ascribed to most subwoofers -- the KSW-10's potency is assured.

The subwoofer's low-pass crossover is continuously adjustable from 40Hz to 120Hz. Connectivity covers all bases with stereo-line and speaker-level inputs, plus a set of speaker outputs (the speaker connectors are all heavy-duty binding posts). A dual-colour blue/red LED display on the front of the subwoofer lets you know whether the unit is on or in standby mode. And while a knuckle rap to the cabinet proved it to be fairly hollow and resonant, we didn't detect that in its sound.

We used the KSW-10 with a pair of Klipsch's new Synergy SLX satellite speakers. The SLXs sound great, but since they produce virtually no mid- or deep-bass on their own, they're totally dependent on the sub to flesh out the sound. The KSW-10 was mostly up to the challenge, but we had to invest quite a bit of time fiddling with its crossover and level controls to achieve a satisfactory blend with the SLXs. The subwoofer rolled out supple bass on CDs and massively deep impact on special-effect-laden DVDs. But most of the time, we weren't all that aware of the KSW-10's contributions -- it took something along the lines of a car crash or an explosion (requiring low-end support) for the KSW-10 really to kick in and shake up our home theatre. While the KSW-10's bass is gutsier and clearly more powerful than the last sub we tested, the Wharfedale SW150, bass-hungry listeners may not be satisfied. Upgrading to the 12-inch Klipsch Sub-12 could provide your SLX system with more bass bravado.
