KEF Q100 VS Q150|Uni-Q technology

The two bookshelf speaker KEF Q100 and Q150, are from the Q series. And a fantastic technology they use in it is the Uni-Q technology. Using this technology means the Uni-Q diver array unit.

The main work of the Uni-Q array is to centralized the tweeter of the midrange and bass cone. The midrange and treble integrated together thus provide the most idea soundstage.

This is the specialty of these two speakers. Because of this technology, the natural and realistic sound can get. The full room will be full fill with sound and throughout the room also.

It also can deliver good frequencies, which is the cause of the more accurate and three-dimensional sound. The listener will get a divine sound and intend to listen more and more.


Q150 is better than Q100 as it has a sleeker look and a more compact size.

  • As bookshelves are small in size, they look cute also well furnished. Seeing the KEF Q100 bookshelf speaker for the first time, it seems expensive to me as well as stylish.

And it actually worth its expensive look. I can go to any home decor beautifully. KEF used a black vinyl exterior using high-quality MDF. This gives the speaker an elegant look.

Two speakers come in the set. And a KEF’s logo on it looks good. The front baffle is attached to the cabinet. And they used durable material for the baffle.

It also has a two-bass reflex design that ensures an outstanding audio experience. It is two way designed bookshelf speaker available in black and walnut color. So, this can go perfectly with your home decor.

Klipsch R-51PM and The Sixes are also have a similar kind of designs.

Winner: KEF Q150


  • Sensitivity means the loudness of a speaker. The more sensitivity rate, the more loud volume or music can hear. And for any rock-type music or action movie, a high sensitivity rate is a must.

Both the KEF Q100 and Q150 speaker have a sensitivity rate of 86 dB. This is not so bad for a bookshelf speaker. It also capable of providing enough loud vibrating sound.

The Q100 had 86 dB of sensitivity, and the Q150 also didn’t change the feature. Perhaps they could change it at a high rate. Then this can be louder.

But as they didn’t change it, both the speaker will provide the same loud. But except these other factors may work behind the loudness.

Frequency Response

Technically, KEF Q100 can produce deeper bass than Q150 due to the low frequency range, but actually, the slight difference doesn’t matter.

Frequency response means the range of frequencies. It refers to the musical tone that the speaker can produce. So, it has a good effect on sound quality.

  • The KEF Q100 bookshelf speaker has a frequency response of 49 Hz – 40 kHz. We know that the human hearing range is 20Hz-20KHz. So, the speaker has the right frequency response.

For this, it can deliver a friendly musical tone and smooth sounding.

  • On the other hand, the Q150 bookshelf speaker has a frequency range of 51Hz – 28kHz. Which is also great for fine-tuning and sound. The crisp sound can hear.

Woofer and Tweeter

In these two bookshelf speakers, there is a woofer made of aluminum. The size of the woofer is 5.12-inch. As a result, there is an emotional and low level of distortion.

And also, a 5.25-inch of Uni Q driver Array also built-in it. Here 1-inch aluminum dome tweeter attached in the center. The number of drivers is two.

The impedance is 8 ohm. The only difference is the maximum output. In Q100, the maximum output 107dB and Q150 108 dB.

Except for the maximum output, the impedance, construction of woofer, or number tweeter are all the same.

These type of woofer and tweeter can produce high and smooth frequencies. The nicer the frequencies are, the more fine-tune or sound you will get. Maybe for this, the KEF kept the same feature in both bookshelf speakers.

Sound Quality

Since the Q150 is a newer model, it outperforms the Q100 in certain areas, most notably in bass performance.

The sound system is terrific in the KEF Q100 Bookshelf speaker. A versatile sound with the clarity can hear. Such sounds that one can listen to for a long time and won’t get tired.

Both the low and high volumes are significant here. And the most impressive thing is the bass. Rich, divine, and powerful bass it produces that can quickly satisfy one bassholic person.

Next, the combination of woofer and tweeter is the best. Because this combination is the cause of delivering rich sound and punchy bass.

The mids are broader and precise. Also, the lows are clear and detailed. The volume can be loud without any distortion. And lastly, the Uni-Q driver array is present for handling the rest of the natural sound.

In a word, this is a blast in this price range.

  • The Q150 bookshelf speaker is uniques for its rich, punchy, and powerful bass. And the realistic and detailed sound clarity is fit for any audiophile.

The low ends are great. That can deliver warm music. And the sound is also three dimensional, which will give you a feel of full of sound around you.

Speaker size: Don’t think that a large bookshelf speaker can produce more sound. Actually, the thing is a large speaker can deliver more volume. If you are considered with volume, you can buy a large speaker.

Otherwise, the size is not a big thing to think about as bookshelf speakers are meant to be small.
