Sound Characteristics and Merits of KEF Q550
KEF really knows how to make gorgeous-looking speakers, even their entry-level Q series speakers are no exception. The KEF Q550 has that iconic KEF look, which looks modern and elegant at the same time. The use of the colors is minimalistic and stylish as well. In terms of aesthetic and visual, it is definitely easy to match with most modern amplifiers but for retro or vintage looking amps, we may have a slight issue. One look at their Uni-Q driver, you would immediately know is a KEF speaker and the Q550 has one as well. The KEF Q550 130mm (5.25 inch) aluminum Uni-Q driver consists of a 25mm (1 inch) vented aluminum dome tweeter right at the center of it, just below, you will find a 130mm (5.25 inch) aluminum bass driver, followed by two 130mm (5.25 inch) aluminum ABR. Since the Q550 uses bass radiators instead of bass ports, this makes it easier for speaker placements.
The KEF Q550 frequency response of 58Hz-28kHz (±3dB) does show a lack of deep bass extension but it is as expected from compact size floor-standing speakers. The recommended amplifier power starts from a low 15 Watts all the way up to 130 Watts. The nominal impedance of the Q550 is 8 Ohms (min. 3.5 Ohms). Up to this point, it shows that the KEF Q550 is quite easy to drive but the speaker sensitivity of 87dB shows otherwise. Probably designed and build to be paired with a subwoofer. This floor-standing speaker is capable of digging deeper into the low-frequency region which is 45Hz but at -6dB. With all this data, we have further filter down the amplifier choices.

The Uni-Q driver unit is certainly an impressive and innovative technology, it widens the sweet spot and allows the speakers to be less toed-in, which also allows more listeners to be within the sweet spot. The accuracy of the stereo imaging and combined with the wide soundstage delivers an almost lifelike performance for both music and movie playbacks. You can easily detect each instrument is precisely placed where it should be and as the music starts, each instrument starts playing with clarity. The stereo image never breaks, providing an almost 3D-like soundstage without breaking the immersion. You will just sit there and keep listening to the music. The vocals sounded natural and smooth, the midrange is sweet sounding.
For movie playbacks, the precision of the KEF Q550 stereo imaging shines again, as the actions and sound effects match exactly to what is happening on the screen. This provided a lot of fun, it is so entertaining to hear and see the scene unfolds. The bass performance is exceptional as well, certainly more than enough for most genres of music. It is taut and rich without sounding exaggerated, has slightly more weight and scale when compared to the smaller Q series bookshelf speakers but a tad slower and less agile than the latter. For movie playbacks, the KEF Q550 floor-standing speakers are unable to deliver enough of the subterranean bass level or even go deep into the bass extension. This is where we really need a subwoofer to improve the home cinema experience.
All in all, the KEF Q550 is a bit bright sounding but not harsh or hard. The KEF Q550 is indeed a talented and impressive all-rounder where it can perform well in both music and movie playbacks. If your playback sources are not bass-heavy, a 2.0 setup will be more than enough. Having a subwoofer integrated into your sound system, might improve and give you a better overall sound quality.
