TLDR: Klipsch KB-15 Speakers Review

Klipsch KB-15 Speakers

The Klipsch KB-15 bookshelf speakers are small but mighty! With a promise of delivering big sound while occupying less space (small footprint) in your home, these bookshelf speakers are highly efficient. And true enough, they fill the room with a powerful sound when placed properly.

User Experience

Immediately after unpacking the KB-15 speakers, you get the impression that they are built to last. The weight is decent enough for you to conveniently rearrange these in the room. 

This Klipsch Icon speaker utilizes Tractrix® Horn technology for more output, lifelike sound, reduced distortion, larger soundstage, and improved reliability by using less energy. If you put it in a small listening room, we’re pretty sure that you won’t miss out on the impactful lows and crisp highs.

But after using it for about two years, few users noticed downsides to these Klipsch speakers that are inherent to their cost and size. 

The sound and build quality are definitely solid, which we will be discussing in-depth in a bit, but the veneer at the corner started to peel off gradually. 

Still, we think this is pretty much understandable for the price that these speakers are offered to the public.


Focusing on the design and build, the pair of Klipsch KB-15 Bookshelf Speakers have a striking black ash wood grain vinyl finish, which allows the speakers to sport modern elegance ideal for any home decor. 

Their material is made up of MDF or Medium-Density Fiberboard meaning they are thick and dense. You will also notice it bears new logos and a 1-inch titanium dome tweeter.

Measuring 7 inches in width and 12.5 inches in height, these Klipsch icon series speakers are small so that it gives you more flexibility in their positioning. 

The appearance of these boasts a beautiful decor appeal just like how the other excellent speakers in the Klipsch Icon series always make a distinct statement worth bearing the brand.

Furthermore, the Klipsch icon speaker utilizes a plastic front plate that is taken up by the woofers and it has a rubber roll surround system. 

It also has a paintable grille, although you can use these speakers without it. We mean, it’s detachable and the speaker still looks good without the grille covers.

What Makes it Stand Out

This 2-way audio speaker system is the smallest speaker system within its price range. And what makes it stand out vs. other good speakers out there is that it has a proprietary Tractrix Horn technology that has been the driving force behind the company’s precise acoustics. 

The horn functions as the speaker’s impedance converter and helps the inefficient transfer of acoustic power to a low impedance atmosphere.

It is designed to observe the four laws that Klipsch believed in – wide dynamic range, flat frequency response, controlled directivity, and high-efficiency sound with low distortion/ reduced distortion. All these are what the speakers offer at a good price!

  • Powerful yet minimalist speaker (small footprint)
  • Mid-range is excellent
  • Produces precise sound/ non-fatiguing sound
  • Design (black ash woodgrain vinyl veneer) boasts modern elegance ideal for any interior
  • It has a paintable grille so it can match any type of decor or interior in the house
  • High output woofer dimensions + aluminum tweeter help deliver big sound as it is intended
  • Fills small to medium rooms with lifelike performances and powerful sound
  • The speakers provide high crisps regardless of the lower or higher frequencies
  • If you want this as the main speaker, its lows may disappoint you
    The woofer is only about 6 inches so don’t expect much bass

Here’s a quick link to where you can buy it! 

Is it worth it to try?

This powerful yet minimalist speaker is worth investing in. It produces a clear sound and serves best both for commercial and residential use. Klipsch likewise promises that this enhanced Icon series will help listeners discover re-engineered drivers with the speaker’s new crossover system.

Overall, this minimalist speaker engulfs listeners while listening to their favorite music and movies!

The majority of people who purchased this KB-15 Klipsch icon series speaker on Amazon gave it a 5-star rating. In terms of features, the buyers also gave above-average ratings for value for money, quality of sound, and quality of material used in this Klipsch icon speaker.

One Amazon customer-reviewed, “I think they sound quite good for the price. Not fatiguing at all. I had read that they’re not as bright as some of the other models in this range and that is what I was looking for. The bass is quite good for a speaker of this size. They’re in a 20×20 room and they fill it quite nicely.” By non-fatiguing sound, he is referring to a phenomenon that happens after prolonged exposure to music or sound.

However, there are still those who gave this bookshelf speaker a low rating. One of them said, “Although these look almost identical to the r-15Ms (minus the copper spun woofer) they are not near the same quality. Was VERY disappointed in the performance. They sound muddled and the clarity I am used to with Klipsch speakers.”


Ken Gammons shared on YouTube that KB-15 Klipsch speakers are “very affordable. I’m using them in a theater setup…They have a very rich and full sound.  [They’re also] perfect if you have a desktop system. [The] vocals come out beautiful.  The highs and mids are just perfect in my personal opinion.”

On the other hand, Digital Stereophony compared Klipsch R-15PM to Yamaha HS5 in a sound test. He wrote in the description box of the video, “This stylish duo has a surprisingly similar sound signature and sound quality…Both are bright in the upper ranges and restrained in the low end, but if I had to pick the winner here it would be Klipsch, as it has a slightly fuller sound with a touch more satisfying bass response.”


In one Reddit thread that asked participant’s opinions on Klipsch KB15, one answered, “The KB-15 is a lower line. They aren’t bad. I actually have a pair as surrounds in my basement.”

In another conversation thread, a Reddit user also shared, “I have kb-15s and I quite like them. I live in a relatively small townhome and they were/are perfect for my needs. There are definitely better speakers out there, but I find them to be perfectly acceptable, especially for $50.”
