Description

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. Exceptional efficiency on or off. Meets global efficiency standards - reducing energy costs for the user. Scratch resistant Ebony finish looks like real wood and covers the entire cabinet.

    • Outstanding! Both speaker and service!
I will never again buy another speaker product from anyone but Klipsch! I purchased this speaker back in 2024 and it sounded great up until this last month when it began showing signs of a problem. When contacting Klipsch, they were exceptionally quick to honor their warranty without question! They were quick, efficient and provided me a no hassle replacement SW without delay! Every once and a while and electronic device fails, it happens. But when it does, it's priceless to have a manufacturer stand behind their product! You can't go wrong with Klipsch! Great quality, great sound and a customer service and support which stands far above all else! Highly recommend Klipsch! This speaker by the way, sounds great, is quality built and is value priced! ... show more

    • 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

    • 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

    • No more Klipsch for me
Bought in December 2025, stopped working April 2026. Klipsch customer service says replacement is 3 months away due to "backorder" despite Amazon having stock. I'm done with Klipsch. But great bass while it lasted. Replaced a cinema 1200 soundbar sub that failed after 3 years. Sad

    • 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

    • Very good integration with Klipsch Reference speaker system.
This is a subwoofer that is vented from the same side as the driver. At normal listening levels, bass is tight and integrates well with the other speakers. It has an auto on feature, but the three position switch was not well marked on the back panel. There is a power on light located on the front panel that is visible through the front grill. If the signal to the sub isn't strong enough to keep the sub on, then the "always on" position will keep the sub on through the listening session. The reason for the four star rating is that the auto on feature doesn't work for me at the levels that I listen at. The finish on the SPL-120 is a perfect match to my Klipsch Reference floor standing speakers in black. ... show more
