Klipsch R-115sw Subwoofer Review – Is Subwoofer Bass Worth Money? 

Last Updated on 1 week by On Trends Gear

American Klipsch has been around for quite a long time now and has established itself as one of the best brands for lovers of good bass and a very fresh level of sound. 

They have gone ahead to launch a new reference premiere series and Klipsch has put out three new amazing subwoofers. 

10-inch, 12-inch, and 15-inch subwoofers. However the 15-inch subwoofers are the best of the lot, and we will explain why. 

Klipsch is the biggest subwoofer on the market right now, so you cannot hide it or fit it into smaller spaces, however, the unique copper-coloured 15 ” Cerametallic bass ensures that you feel the superb rocking impression. 

They made use of the bass reflex principle when making the cabinet but they also adopted a slit-shaped reflex port as opposed to the normal round bass-shaped port. 

The fore part is made of simple vinyl and has a very brushed surface structure. 

Klipsch R-115sw Subwoofer Features:

Klipsch R-115sw Subwoofer

it has an amazing slot port to help you get the best sound and bass out of the subwoofer even if you back them into a corner.

  • 400-watt RMS amplifier (800 watts peak power)
  • compatible with the wireless audio adapter kit for an easy connection to a sound system
  • 15" spun-copper Cerametallic woofer
  • Dimensions: 21.5" H x 19.5" W x 22.3" D
  • All-digital amplifier delivers 800 watts of dynamic power
  1. 15-inch spun Cerametallic structure to keep it strong and durable.
  2. A satin plate underneath to help separate the subwoofer from the floor and protect it from harm.
  3. Auto power feature: This feature makes your subwoofer turn on when it receives a signal rather than you manually using the power button all the time. 

Performance and Sound Quality: 

It is quite rare for you to see so much quality in a subwoofer for the price that they go for. Also, large bass elements seem to be very scarce nowadays and this one seems to come with a large petrol engine. 

None of the other subwoofers can create as much life and bass as the R-115SW. The bass reproduction of this sub is very powerful and it is very dynamic and unique.

 It has a deep synth bass which gives it a very refreshing feeling and you are definitely going to enjoy yourself. 

The 15-inch can last much longer than the other smaller subwoofers. These subwoofers are the most exciting subwoofers on the market right now as they hit very hard and precisely contrary to most reports. 

The R-115SW is also very impressive in regards to its frequency range. 

Klipsch manages to maintain a really good sound pressure all the way down to 20Hz while other subwoofers gradually roll off. 

The slit shape was created precisely in order to minimize door noise according to Klipsch, but we have also noticed some blowing sounds at extremely high volume at low frequencies. 

But the Klipsch sub is so ready to tear down your house or anywhere you want it! However, there are also a few problems due to the fact that the bass is so good. 

Because the subwoofers play so powerfully, there are going to be problems with the acoustics in the room. 

Klipsch r 115sw Subwoofer Bass Testing & Connection Set up: 

I set up the subwoofer in a way that the twin R-115SW both flanked the Klipsch RS280 towers that are also included in the 7.2 channel set. 

This method takes a lot of space, so it’s important that you have a moderate room at least. 

This system is perfect as a subwoofer that is even slightly bigger would be considered too big for a moderate space. 

Also, I made use of an 80 Hz crossover when integrating the subs with the tower speakers. 

Also, while I was taking measurements of the sine wave sweeps with REW, I discovered that the bass response was much better around my main listening position. 

I proceeded to measure a 12 dB spread between the peaks and the nulls too. 

Overall Music & Movies Sounds Performance: 

The R-115SW is a very efficient subwoofer that produces an enormous output of bass, this particular sub is very good for music and movie watching as the sounds are very clear, and also this sub is very effective in the way it works even in the 20-30 Hz frequency region. 

The R-115SW always gives a superb performance regardless of what you are watching and the conditions in which you are watching anything, they leave out room for excuses. 

I ran some sine-wave sweeps and I was able to add a large amount of energy to a whole room with just one of the subs. 

Also, I totally locked the room from 18Hz up and there was still so much headroom to spare. I measured the sine waves at 20 Hz and it measured 100 dB at my main position for listening.

Klipsch’s 18 Hz low-frequency rating is also very accurate as I also learned.
