I also maintain a Mackie 8" powered subwoofer under the desk.Īs a matter of quick background information, a good 30+ years ago, I used to delve into a variety of room-sized audio components, including the (then) wonderful KEF 104 II and their flagship model, the 105. My audiophile efforts of late are confined to a desktop, near-field environment, and I use compact gear (due to space). Prior to obtaining the KEF Q150's, I was perfectly happy listening to a pair of Warfedale D320 bookshelf speakers.
Overall the the system sounds effortless, when reproducing all musical genres at various levels.
The overall result provides seamless integration, very wide frequency response, high dynamic range with fine imaging/sound-staging. The subwoofer utilizes a digital power amp that provides much punch and weight.) It took much time to select crossover frequencies, amplitude, as well as phase which fortunately I may adjust continuously between 0 and 180 degrees. (I've settled on a vintage analog MOSFET power amp to drive the Q150s. One may also select an appropriately optimized power amplifier. Dynamic range is increased and potential distortion is lowered. With the 150's relieved of lower bass, they're able to focus on upper bass, midrange, and highs. Ultimately I paired my Q150's with a subwoofer and a custom-designed active crossover network. I prefer a pinch more neutrality which I achieved with additional damping material. To me, the upper bass tends to the 'warm' side which is likely preferable to most listeners. I don't find the Q150 tweeters to be harsh yet they are revealing and can point out weaknesses in up-stream electronics as well as in recordings. While the Q150's are tolerant of lesser quality amplifiers, they do benefit from higher quality amplification: I could readily identify differences between power amplifiers, prompting me to settle on one in particular. However over time (after break-in) I preferred listening without the foam inserts. Initially in my room, I preferred listening with the supplied foam cylinders inserted in the rear ports. While I haven't yet taken any measurements, frequency response sounds acceptably linear, and amplifier load seems to be an easy one making for an easy match with most any decent amplifier (or receiver, if you're so inclined). Right from the start, the Q150's impressed with wonderful detail minus obvious stand-out sonic aberrations, stable imaging, and neutrality. So are room placement considerations with some experimentation. So how does it sound? Just like most all loudspeakers, break-in time is required. (It is here at this price point certain material/construction compromises needed to be made this is understandable.) All are integral parts, yet from experience the final implementation still requires much testing, listening, refinement to arrive at an exceptional loudspeaker. Of course an accurately-designed enclosure is part of the equation.

The Q150 sets a new standard using a specially-designed 'coaxial' (UniQ) driver with state-of-the-art cone material and finely-integrated well-designed tweeter as well a precision crossover utilizing quality components. KEF also developed several well-reviewed milestone loudspeaker systems.

The famous BBC LS3/5a monitor employed KEF drivers as did other audiophile-grade loudspeakers of that era by IMF, Fried, JR, etc. Years (OK, decades) ago I employed KEF drivers such as the B110, T27, and B139 in some of my loudspeaker designs.
As a long-time audiophile, audio engineer, and having previously designed several loudspeaker systems, I appreciate what KEF has achieved in this small package at this price point.
