KEF Q900 Amplifier

When it comes to the flagship speaker of the Q series, it is always huge in size and the Q900 is no different. The KEF Q900 looks like a floor-standing speaker that is more than capable of delivering powerful sound and likely demands a lot of power from its partnering amplifier. Are you currently in the market looking for that matching amp? If you say yes, then please continue to read on.

We are gathering a list of potential amplifiers which you can match with your Q900 speakers. In order to do so, we will need to find out more about its sound characteristics and also whether do they have any limitations. Once we have all these details, we will then be able to pick the right matching amplifiers and pair them with KEF Q900. So without further ado, let’s start with finding out more about the speakers.

Sound Characteristics and Limitations of KEF Q900

In terms of speaker visual design, the KEF Q900 doesn’t have that elegance in them, it is more of a power statement and will certainly stand out in most homes. Still, aesthetically they don’t look bad and as long they are placed in a large listening room, they will fit in nicely (sonically as well). Due to their cabinet design, they will blend in well with most amplifiers so it wouldn’t be an issue. The ‘intimidating’ aspect of KEF Q900 will be the multiple large-size drivers located at the front of the cabinet but for bass fanatics, the Q900 looks promising. KEF’s iconic Uni-Q driver array is big, it is an 8 inch (200mm) aluminum cone with a 1.5 inch (38mm) vented aluminum dome tweeter right at the center of it. Below the Uni-Q driver, will be an 8 inch (200mm) aluminum bass driver followed by two 8 inch (200mm) aluminum ABR. There are no bass ports but still the KEF Q900 requires plenty of breathing space around them.

This pair of floorstanders have a really impressive frequency response for their price range, it is 32Hz-40kHz (±3dB) which is a really wide range. The speaker sensitivity is at 91dB, which is good but we expected a little higher. The recommended amplifier power is quite intriguing as it is only between 15-200 Watts. The nominal impedance is 8 Ohms and with these data, it seems like the KEF Q900 speakers are quite easy to drive. Nevertheless, we have what we needed to further filter down the potential amplifiers.

The KEF Q900 packs plenty of bass output and they are the quality ones, it is taut, accurate, and as agile you can expect from a floor-standing speaker. Q900 digs deep and delivers the low-end frequency prominently, it adds weight to the overall sound reproduction, making it sound powerful. These speakers do not need any help from subwoofers unless is about reproducing very deep bass from 30Hz down to 15Hz. The midrange is lush, probably because of the prominent low ends capability of Q900, it still sounded natural and can be a tad too warm for some. The highs are clean sounding and with clarity, but at high volumes, it may start to get too harsh-sounding.

Also, at high volume, the bass may become too prominent which does affect the clarity for the rest of the higher frequencies. The overall treble will likely need to be tamed down a little via EQ at high volumes though. The most fun part about the KEF Q900 music presentation is how they deliver such a large and spacious soundstage. The stereo imaging is spot on as well, which makes a very entertaining performance overall. I bet the Q900 will provide the same fun factor for home theater use as well. To nitpick, these speakers do lack the details and insight, but still, at this price point, we can’t really complain.

The KEF Q900 is a talented speaker for both music and movie listening, it would probably do better in a home theater setting as the low-frequency reproduction is its greatest strength. They are also quite warm sounding which is smooth and relaxing until the treble starts to break up at loud volumes. Now we have all the necessary details and also have concluded that the KEF Q900 doesn’t require bass support from a subwoofer, with these we have filtered out the best matching amplifiers for Q900 floor-standing speakers.
