Q150 Bookshelf Speaker Pair
The remarkable Q Series bookshelf speakers excel when space is limited. Featuring the signature KEF Uni-Q driver array with Computational Fluid Dynamics (CFD) port design, the Q150s deliver detailed natural sound with high clarity and tight bass.
Priced as a PAIR of speakers. Speakers Grilles are sold separately.
|"Sit anywhere" Uni-Q Sound
At the heart of the evolved Q Series is the Uni-Q driver array. KEF's signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced by KEF's 'tangerine' waveguide over the tweeter dome.
|Uni-Q sound taken to the next level
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.
To optimize the resolution and purity of the Q Series bookshelf speakers, the Uni-Q driver has been repositioned to the center of the cabinet to reduce unwanted internal resonance and adds refinement to their sonic clarity and detail.
|CFD Designed Port
Featuring a Computational Fluid Dyanmics (CFD) port design with the port repositioned to the rear of the speaker, clarity is improved by reducing the audibility of the midrange leakage through the port. The geometry of the ports have been tuned to minimize turbelence at higher levels resulting in a reduction in port noise and less LF compression.
Great speaker all-around for the moneyLet 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.
Worth Every PennyIncredible 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.
