The Klipsch SPL-120 makes a statement both visually and acoustically, thanks to its sleek copper-and-ebony look and, most importantly, its crisp and powerful bass output. The 12-inch front-firing woofer is made of Klipsch’s trademark spun-copper “cerametallic” material, keeping it lightweight but rigid and minimizing distortion. Its efficient class-D amplifier offers a 600-watt peak, but the more relevant number is its nice 300-watt RMS, which is the power it’s rated to handle on a continuous basis. With a frequency response ranging from 24Hz to 125Hz, it delivers booming lows that can’t be denied.
Other features on this premium subwoofer include an energy-saving standby mode and controls to fine-tune the synergy among the subwoofer, speakers, and your room. It has dual RCA/LFE line-in inputs, and if you opt for a separate Klipsch wireless kit, you can have the speaker connected to both the wired and wireless inputs at the same time without needing to switch. When it comes to powered subwoofers, different sizes or power capabilities may suit different rooms and needs, but if you have a moderately-sized space and nice speakers to go with it, it’s hard to go wrong with the SPL-120.
