Klipsch R-115SW: Where Tech Meets Art

Klipsch R-115SW review & specs

The model has first been released in 2014 and has been extremely popular ever since. The price point remains stably high. Klipsch R-115SW will cost you around $900 regular retail price. You might think about getting your hands on it during the Black Friday sale but I would not bet on that.

R-115SW is a masterpiece and is at the top of the list among all the Klipsch subwoofers. Even if you choose to save and go refurbished or preowned I would suggest you go for it. The woofer is legendary.

The spun 15-inch ceramic subwoofer with a copper finish looks really amazing. These cerametallic subwoofers are the Klipsch signature. Whenever you have friends and family over most of them will be able to immediately recognize the brand. Trust me, I checked on my parties.

The woofer weighs about 87 pounds. It might sound like pretty heavy and dangerous. This weight is pretty low for this class of hardware. The cabinet itself is made out of the light polymer panels with a velvet matte finish meant to highlight the copper color in the center.

The wireless connector is made in the same seamless back matte vinyl material making it blend in invisibly. Meaning that the bass will feel like magic coming from heaven, or hell, maybe.


I loved Internal Flare technology. The inner front-firing slot port design is built to minimize the port noise. I know the R-115SW specs sound pretty complex but I throw in some tech terms just to give you a proper idea of how cool this woofer is.

Klipsch R-115SW settings also allow for it to be seamlessly added into your Klipsch speakers family. The Variable Phase Control technology, as well as the Low Pass Crossover feature, are meant to give you the proper level of bass as well as weave it into the speakers’ tones.

You will have an impeccably smooth bass distribution throughout the entire room so everyone gets to enjoy. I tried carrying it from one corner to another and testing it over again. And yes, the technology works.

Performance & Sound quality

Be ready to experience the breathtakingly low frequency. At the same time, Klipsch has managed to achieve minimal distortion or cone breakup.

Since the woofer is designed with front firing in mind you can place it anywhere in the room not loosing on the sound quality. Especially if you use it with the wireless kit.

The sound seems very effortless, clean. I recommend trying it out on some modern horror or catastrophe movies to feel the trembling on your skin. My Klipsch R-115SW review is not enough for you to feel the true sensation this cerametallic woofer gives. You should give yourself a chance to try it out one day.


Invest an additional $200 into a wireless connection kit for this woofer. It will make the R-115SW setup so much easier for you. By the way, this wireless kit will work with other smaller Klipsch woofers as well. I tried to connect R-115SW with the AV receiver through the subwoofer input and as well as through the wireless connector. Both are pretty easy even for an average user. The setup is fairly simple if you follow the added manual.

The foreseen inputs make it compatible with most AV receivers out there. L/R, RCA, LFE, line-level inputs are available. So you do not have to sweat about aligning it with your home theater.


All I have to say is that Klipsch R-115SW is for you if you want:

  • The most outstanding bass out there
  • Perfect harmony with all the speakers in the house
  • Placement versatility
  • Wireless tech
  • Envy from all your friends and family
  • Pure hate from all your neighbors
  • Internal Flare technology
  • A timeless design that will be relevant for the years to come

By all means, do get it. Make sure you have sufficient funds though. The warranty is not that clear at least for me. In the best outcome event, you can be covered for 1 year if you buy from Amazon or other official Klipsch reseller.
