A step-up from our Reference Series subwoofers, The SPL Series have best-in- class MAX output levels making them high-performance subwoofers at affordable prices. Cerametallic woofers are exceptionally light and extremely rigid, providing remarkable low frequency response with minimal cone breakup and distortion for higher, cleaner output using less amplifier power. The built- in, high efficiency amplifier features an analog preamp design, which maintains the original signal path for cleaner, true-to-source reproduction. The class D output stage ensures MAX efficiency for MAX output, detail, and low frequency power. Proprietary internal geometry that minimizes port Noise for clean undistorted low frequencies. The front-firing design allows for placement flexibility. The Klipsch wa-2 wireless subwoofer kit (sold separately) allows high resolution wireless connectivity for easy placement anywhere in your room and optimizes output and low frequency response. Connect up to 4 wa-2 wireless Kits to compatible Klipsch subwoofers in a single room for a completely wireless connection. Low pass Crossover and variable phase control allows you to tune the subwoofer to your Klipsch speakers and to your room, establishing the ideal level of bass. Line level/ LFE RCA inputs ensure compatibility with home theater receivers. Both the RCA and wireless inputs can be utilized, giving you the ability to use A single subwoofer with multiple system in the same room. For example, you can use the wireless input for your home theater set up and the RCA input for your 2-channel system, without needing to switch inputs when changing between systems.

    • An Absolute Beast of a Subwoofer — Massive Upgrade to My Home Theater
This subwoofer completely transformed my home theater setup. The Klipsch SPL-120 is an absolute beast when it comes to bass performance. The 12-inch driver and powerful amplifier deliver deep, clean low frequencies that you can both hear and feel without the muddiness that cheaper subs often introduce. Before buying this, I was using a Boston Acoustics subwoofer that originally cost well over $1,500. Surprisingly, this Klipsch actually performs better in my system. The bass is tighter, more impactful, and integrates with the rest of my speakers much more naturally. Movies now have that cinematic low-end punch, and music sounds fuller and more dynamic. Another thing I appreciate is how adjustable it is. The phase control, crossover settings, and gain allow you to dial it in easily depending on your room and speakers. Once tuned properly, it disappears into the system and just enhances everything you’re listening to. The build quality is also excellent. The cabinet feels solid and well constructed, and the Cerametallic woofer looks fantastic behind the grille. It’s definitely not a small subwoofer, but the size is justified by the performance. Overall, this is one of the best value upgrades I’ve made to my audio system. If you’re building or improving a home theater setup and want powerful, clean bass without spending thousands, the SPL-120 delivers far beyond its price point. ... show more

    • Works good.
Tried one of those "test" videos on YouTube that goes from 1 to 100 Hertz. You actually start hearing a clean note starting at 18 Hertz even though it's only rated for 24 Hertz. Around 36 Hertz I had to put acoustic foam pads on two nearby picture frames and the hall closet to damp out the rattle. I bought it to hear the opening notes of 2001 A Space Odyssey (A.K.A. Thus Spake Zarathustra) which is 32 Hertz. What you normally hear on reasonably good systems is the 64 Hertz first harmonic, which gives you the impression you're hearing the opening note. It also comfortably handles the lowest note on a piano, which is 27.5 Hertz. Good system. Worth the price. I'm driving it directly from a pair of Klipsch R-51PM speakers using a coax RCA audio cable. The high end on the R-51PMs doesn't matter because my ears have no high end. ... show more

    • Just what I needed, finally!
I don't know why it took me so long. A few years ago, I bought a 12" Polk Audio PSW505 to replace an old Sony 10" subwoofer that didn't really cut it for me as my home theater setup evolved. It's been great in most use cases, except oddly enough a lot of newer action/sci-fi movies and shows started to cause the sub to make an awful burbling/rattling noise that sounded like it was being pushed past its limits. It might be due to the audio format, I'm not 100% sure, but new shows like Star Trek: Discovery would be problematic whenever the lower frequencies increased, whereas older series wouldn't have any trouble. I had tried adjusting the low pass filter and the volume, but the only way to really solve the issue was to turn the volume down so far that it basically defeated the purpose of having the subwoofer in the first place. So I'm not sure what was going on there. At any rate, a while back I upgraded my front towers and center channel to Klipsch RP-series monsters and I had been holding off on the subwoofer, but I finally pulled the trigger after dealing with that rattling from the Polk for too long, and bought the SPL-120. Problem solved! Strong, house-shaking bass with no rattle. Strong enough that I dialed it down a bit to keep it from overpowering the rest of the audio. Strong enough that when an explosion hit on screen, my girlfriend at the other end of the house went "holy crap!" ... show more

    • It's Klipsch! nuff said
I'm not sure if Klipsch needs any more reviews saying how great their speakers are... but all the good ones are true! I was skeptical about some reviews stating about "shaking the house" but it's really NO exaggeration - even on relatively toned down settings some sneaky occasional low tone bursts (explosions or say console startup sound) rattle the interior doors some 25ft away. Also thanks to Klipsch partnering with other names in sound industry your amplifier might have bunch of additional settings just for your specific speaker. Outstanding for tuning it just how you like it. Thanks Klipsch peeps! ... show more

    • Wow! This is a good subwoofer for under $400!

I am an audiophile, I like to hear full frequency spectrum, little distortion and loud! Well, this subwoofer seems to do the trick. Big upgrade from my old Klipsch K-100SW. Noticeable difference from the first time I hook this sub up. My god, this sub goes all the way up to +15db on my amp, speakers distorting before this subwoofer starts to fade away. I bought a SVS PB1000 for $800 at best buy and wasn’t impressed. This $360 sub is definitely outperforming the $800 SVS sub. Highly recommend this sub. And unfortunately my room have bad acoustics thanks to the 15ft vaulted ceiling and the size of the open space. This can now keep up with the towers speakers and still fill the room up with amazing bass. Can’t wait to try it with a movie tonight! Will be calibrating this better, so far so good, I love this sub! ... show more

    • AMP prone to failure.
The amps are very unreliable. It sounded great but after 1 year the amp failed. Klipsch agreed to send a replacement but that process is taking over 2 months. I would strongly stay away from Klipsch for subwoofers and go with a company like SVS who has better support and products.
