Klipsch R-112SW: absolutely boomy-boom

Klipsch R-112SW review & specs

R-112SW has an absurd amount of power is always a good way to get high performance at lower volume levels without straining. Needless to say, this thing has vast reserves of power, and you may even find yourself feeling slightly self-conscious when certain "bass events" hit late at night. In the Klipsch R-112SW review you will read about very clean, tight bass and sturdy construction, and distinctive good look.

When it comes to subwoofers, there is no replacement for displacement - bigger is usually better. But you've got to consider room size, and placement, as well as that, can make all the difference. It sounds like and probably is, capable of "flat" response down to at least 24 Hz as advertised and also capable of high SPL relative to competing products.


In short, there are no fancy R-112SW specs here or "auto equalization" to help you along, nor any built-in EQ features, but for this money, this is perhaps the norm, and those features are redundant given some of today's AV receivers. It is somewhat hard to "dial in" at first, but eventually, it will be settled for.

The lows and responses are crystal clear with absolutely no distortion and the crossovers to and from other speakers are seamless. The sub is very deep, powerful and dynamic. At low volume it grumbles like a dinosaur, sometimes it behaves like a monster wanting to get out of a cage. This sub I highly recommended to anyone who loves both music and movies, Klipsch R-112SW picks up every note that being played on the low end. this subwoofer gets a ton of bass out of a fairly minuscule amount of woofer movement.

At just about the maximum comfortable volume level for a room, it is absolutely shivering timbers with only a modest amount of peak-to-peak movement. No port sounds at all were audible.

Performance & Sound quality

There is a huge difference in sound and feel. R-112SW blends in perfect. It adds in the thumping and room shaking without sounding too boomy for the lack of a better word. It reaches down pretty low. It doesn't hit as hard as a good 15" of course. At the same time though there is no need to constantly adjust it when you change the type of audio your playing. Sounds great though and I feel like it is worth the cost.

It sounds deep, aggressive, tight, and fantastic. At first, that slowish "ported sound" with "too-much-overhang" is there on music tracks that dug ultra-deep. But the floor and wall shaking sound are there to a level that is truly awesome. The Klipsch had that great "effortless" sound. This Klipsch subwoofer is very impressive. Great tone, and captures not just the sound, but the feel of the lowest lows in your music and movies. It's hard to find a sub that produces both a "tight" bass sound, while also being "smooth." No distortion with this unit. The size of the speaker helps it to easily reproduce very low frequencies without distortion, and without having to crank the volume to get the effect you want.


R-112SW setup on its own in a corner, I struggled to render out some of the "boominess" in the very low notes (probably 40 Hz or lower). That would be true of any single subwoofer in this location. That is also less of an issue if you have a receiver that can help EQ your "room modes". Also, this is less of an issue if can place it closer to the center of a wall - the sweet spot is along that wall somewhere.

Subwoofer placement can be a bit tricky, but once you have it positioned properly, the sound is much fuller and you can feel the bass notes when you should be able to feel them, and yet the sub does not overwhelm. Klipsch R-112SW settings are a breeze and took a total of 30 minutes, including mapping everything.

This unit runs considerably cooler, has amazing room-filling sound, and has a great interface with all of the connections, streaming services, and sound enhancements. Voices are clearer and the sub provides ground shaking, wall-rattling sound. All for an incredible price.


R-112SW produces a full smooth bass that immediately makes you smile. One of the best-powered subwoofers in the price range, clean, powerful, gets low. This sub looks incredible with the cloth cover off, and I'm sure that's the main reason all the knobs and switches are on the back. This subwoofer definitely rattles any medium-size room. Klipsch R-112SW sound can create an atmosphere.
