As a music lover, I’m always on the lookout for high-quality audio equipment that can deliver an immersive listening experience. When I first heard about the KEF Q150 speakers ($599USD), I was immediately intrigued. The price point and KEF’s reputation truly sealed the deal for me. After spending some time with these speakers, I can say without hesitation that they are some of the best bookshelf speakers on the market today.
First, let’s talk about the design. The KEF Q150 speakers have a sleek, modern design that would look great in any home. The speakers are relatively compact, measuring just under 12 inches tall and 8 inches wide, so they won’t take up too much space on a bookshelf or desk. The cabinets are made from MDF and feature a matte finish that looks and feels great. The speakers come in black, white, or walnut so you can choose the color that best fits your decor. KEF was out of stock on the white model when I ordered mine, so I chose black. But I’m not going to lie, the white Q150’s are gorgeous.
The standout feature of the KEF Q150 speakers is the Uni-Q driver array. The Uni-Q technology allows the midrange driver and tweeter to be placed in the same location, which improves the sound quality and creates a more cohesive listening experience. In layman terms, it’s going to offer you a wider listening point or sweet spot. The 5.25-inch midrange driver is made from aluminum, which helps to deliver accurate and detailed midrange frequencies. The 1-inch tweeter with waveguide is also made from aluminum and is capable of producing crisp and clear high frequencies (Freq. response 51-28,000 hz ±3 dB)
When it comes to sound quality, the KEF Q150 speakers do not disappoint. In fact, they just plain sparkle and shine! I paired these speakers with a vintage Sony GX90ES receiver and was blown away with the results. The soundstage was wide and immersive, with instruments and vocals coming through with incredible clarity and detail. The bass was surprisingly tight and impactful, without being overpowering or boomy. The midrange frequencies were especially impressive, with vocals and acoustic instruments sounding warm and natural. For best results, KEF recommends a receiver with power between 10-100 watts per channel. With an impedance of 8 ohms most systems should have no problem driving the Q150’s
It’s worth noting that my normal system consists of a similar sized pair of PSB Image B25’s as well as a 12” powered subwoofer. As of the writing of this review, I have not bothered to even connect the subwoofer with the KEF Q150’s because it is just unnecessary. Low end on the Q150’s is beautiful and plentiful without being overpowering.
I tested these speakers with a variety of different genres, including jazz, rock, hip-hop, and electronic, and they handled everything with ease. One of my favorite albums for testing is Kind of Blue by Miles Davis. Miles’ trumpet sounds bright and clear, while Coltrane and Cannonball Adderly’s saxophones have warm and full-bodied tones. The drums sound tight and punchy, and the bass has just the right amount of impact and detailed clarity. Listening to this album on the KEF Q150 speakers is an incredible experience that makes me feel like I’m in the room with the musicians.
Another thing I appreciate about the KEF Q150 speakers is how versatile they are. They are comfortable as front speakers in a home theater setup, or even as surround speakers in a larger system. This makes them a great investment for anyone who wants to upgrade their home audio rig over time.
Setting up the KEF Q150 speakers is a breeze. The speakers do not come with removable grill cloths, But the optional magnetic grill cloths available from KEF are brilliantly designed and offer good protection. I set mine up according to the recommended wall distance of 9 inches which allows bass frequencies to move about without muddying up the sound with too much bass.
The speakers have screw-in terminals on the back, which makes it easy to connect them to your amplifier or receiver. The speakers accept both banana plugs and bare wire, so you can choose the connection method that works best for you. I was badly in need of new speaker cables so I went shopping on Amazon for some accessories and built my own custom cables with fancy mesh sleeving and heat shrink.
The price point might be a negative factor for some, but I would highly recommend demoing these at your local stereo shop. You can find a KEF dealer here. Once you hear these, I know you’ll want to take them home. The other potential downside for some might be their size, while they are 12 inches tall by 7 inches wide, it’s the 11 inch depth that might be problematic for some bookshelves. To be honest, I see this as an opportunity to accessorize and, with some nice floor stands, display them front and center. Because the KEF Q150’s can definitely hold their own as the primary drivers of your home audio system and they’ll look fantastic doing it!
