Product Features
The Q150 proves that the best things come in small packages. A Uni-Q driver and CFD port mean it punches way above its weight
"Sit anywhere" Uni-Q sound
The Uni-Q driver array places the tweeter in the centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever. The result, enhanced by KEF's 'tangerine' waveguide over the tweeter, is a more accurate three-dimensional sound that's dispersed evenly throughout the room.
KEF Q Series Uni-Q Driver Array
Tweaking the tweeter
With the addition of the damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass.
KEF Q Series tweeter upgrades
A word about drums and bass
The Q Series reproduces the nuances of bass instruments with ease. With a larger roll surround and new suspension KEF drivers produce cleaner bass at high volumes.

A new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality.

KEF Q Series bass drivers
New system design
Putting the Uni-Q driver in its own sealed cabinet reduces the load on the cone and increases clarity and detail while delivering cleaner bass. Midrange clarity is enhanced by driver improvements that mean the DC blocking capacitor to be eliminated from the crossover, allowing a more natural roll-off between drivers.

  1. KEF Q150 is Great Desktop Speaker!!
    I have had the KEF Q150 for about four months. I use it at my computer desk with 50 watt integrated amp. My main source are my computer music files. The sound is very natural and well balanced. It plays what is on the recording. Grand piano and violin sound wonderful. I use also for my old rock music like the Stones and the Beatles. Bass is tight and tuneful. Like that the speakers are not too big. Well recommended.

  2. Q150's are Very Good Speakers
    I use my Q150's for desktop computer set up. I have small 50 watt amp driving them with flac files. Excellent sound. They really shine with jazz and classical piano. Voices are well done. The KEF Q150's are balanced from top to bottom. I like the grills to protect them from my soda fizz spray. The speaker covers are magnetic and look good in black oak. Recommended.

  3. Great speaker all-around for the money
    Let me say especially at the current price at $300/pair, these Q150s offer a very solid product in terms of build quality, aesthetics, sound quality, and respond to a fuss free approach to placement and setup.

    I would have liked to see the grilles included like with most speakers but these speakers look great without grilles with no visible screws or pin cups thanks to the magnetic grille design. My ratings for price and value are based on the regular MSRP. At the price I paid, I would give 5 stars all-around.

    The only potential downside sound wise I can think of is that dialogue/vocals need some volume to sound their best. Not an issue for HT use or music at a moderate volume, just low level night or background music listening. On the flip side, these speakers aren't fatiguing or bright in any way and so listening at somewhat loud levels is very pleasant. Treble is very smooth and extended.

    My previous speakers include SVS Prime bookshelves and center and Sony Core bookshelves and center before that. These Q150s are a lot better in most ways than both and I have 5 of them paired with a sealed Rythmik L12 sub and Yamaha Aventage RX-A2070 AVR in a bedroom 5.1 HT setup. Given the very small and sealed nature of my room (~1200 cu ft), this setup is very powerful and I don’t need to go past -30dB MV on the Yamaha to fill the room with very clear, precise, and powerful sound. I found using the supplied port plugs to turn these into sealed speakers with a global 100Hz crossover in the AVR produced the best bass response in my room.

  4. Worth Every Penny
    Incredible amount of detail while sounding fantastic across all frequencies. Directly compared to a pair of JBL LSR305s and the Q150 are a noticeable upgrade. In a desktop setup you may even be fine without a sub woofer as these are able to deliver an amazing amount of bass for their size.

Q150 Loudspeaker Review - Hi-Def Digest
"Perfect for a 2.0 or 2.1 desktop setup OR as rear or side surrounds, the Q150 bookshelf speakers are the most affordable Q Series bookshelves, and they do a respectable job with mid-to-high range vocals, music, and sound effects. However, you definitely need a subwoofer to fill in the missing sonics.”
