About this item

Written by Crutchfield's Kramer Crane

Explosive bass for your home theater

I'm a huge fan of Klipsch powered subs — so much so that I have a 12" sub in my own surround sound system and absolutely love it. The depth and power of bass that it delivers is incredible. If you want to add the same performance to your system, consider the Klipsch SPL-120. 

This hard-hitting 12" sub is powered by a 300-watt RMS amplifier — enough "oomph" to shake the walls but also provide controlled, accurate bass. It's the kind of sub that makes dinosaur and spaceship movies take on a whole new level of realism in your room. 

Easy system integration

Line-level and LFE (Low-Frequency Effects) inputs let you easily connect the SPL-120 to almost any home theater or stereo receiver. Its back-panel gain, crossover, and phase controls help you fine-tune the bass to your liking, and blend its sound into your system.

Put a stop to shaking, rattling, and rolling

Quick story: my living room has glass bookshelf and fireplace doors, along with tall windows that line three of its walls. All of these used to rattle like crazy when bass hit during movies. It drove me nuts!

One day I decided that I'd had enough. I bought an isolation platform to decouple my sub from the hardwood floor. Voila! Just like magic, the rattling and vibrations instantly disappeared. I even had to dial the sub back because the bass was suddenly stronger. It is without a doubt the best money I've ever spent on my system.
