World famous Uni-Q technology for a natural sound stage
The KEF Q550 uses a famous KEF technology to great effect, with the Uni-Q drive unit. This involves positioning the treble unit in the middle of the woofer, creating a single point source for sound across the frequency range. The end result of this is a broader, more cohesive sound that offers excellent stereo within a wider listening area.
A new damped loading system greatly reduces distortion, giving a smoother, more detailed top-end. The "tangerine" wave guide system helps the treble integrate more smoothly with the mid-range. Another improvement with the Q550 is the sealed top compartment - meaning that treble and mid-range aren't affected by the air movements from the bass units.
Aluminium woofer cone with Z-Flex surround for low distortion
Made from lightweight yet rigid aluminium, the woofer units are fast to respond and linear in their response. This helps give life-like dynamics and low levels of distortion. Using technologies developed in their high-end Concept Blade speakers, the Q550 offers attention to detail not usually seen in speakers at this level. The Z-Flex woofer surround gives superior cone control, helping it blend seamlessly with the treble unit for a more even and consistent sound.
Extra woofer and twin ABRs for bass boost
Within its elegant floorstanding cabinet the Q550 house no fewer than three additional bass woofers. One of these is powered and is dedicated entirely to bass below the mid-range unit. Working rather like a subwoofer, this enables the Q550 to offer consistent and reliable bass that's both deep and sustained. Improving this further, twin ABRs (Auxcillary Bass Radiators) utilise energy within the cabinet to further enhance and sustain the bass response.
Plinth included for enhanced stability
Coming complete with bolt-on plinths, the Q550 offer excellent stability. The design stretches out the spikes to give the highest level of stability possible from such a slender speaker. This has the effect of reducing distortion as the cabinet is more likely to stay in position and not 'rock' with louder music. Yet another great piece of attention to detail is that the spikes are also effortlessly adjustable from above - saving time and hassle when it comes to setting up.
Boost the bass while saving space, with the slender KEF Q550 speakers.

Rated 1 out of 5 by Keg oh no from Who knows where a dream can lead you My purchase is unopened as I had to invest in a new amp recommended to give the speakers a chance to give you what keg intended. Here enters the Cambridge cx Ca 61 and QED cables even though I have meters of good cable( again to do justice to the speakers) . Then enters the preamp because watching a review I found to my dismay it has no phono as Cambridge believe ( according to this reviewer ) that if you can afford this amp you can afford the preamp. Wow, I had two amplifiers and wanted to play my unplayed records of 20 years. In truth, I gave good pairs of speakers to charity and so far everything I have purchased is unopened and probably stay that way as the joy had gone- The first thing I asked was could have a demo at which point I could know what I need but you didn’t have any Q550s to let me hear. That day was my judgment day as I am not blessed with a ton of cash and as a pensioner who wanted to let my ears take me back to a lifetime of memories via my music- So if I had left that day without purchasing I probably wouldn’t have returned as it’s extravagant . The sales people was great and no fault is attached to them for my let down however, enabling me a demo would have changed a lot . Your advertising brags about demos that answers all your questions but !!!

Rated 5 out of 5 by XXSCANNERXX from "More impressive than I imagined" I bought these as a test for my system setup. Extremely well presented speakers with a tight sound, obviously they need to be worn in. Deciding to buy the Q950 now. Richer Sounds done a fantastic sale and helped me decide what was right. Overall very good experience from purchasing to setup. Many thanks

Rated 5 out of 5 by fishpond09 from Excellent speakers for the money! Purchased a pair of Q550s from Ali in the Bromley Branch. Ali was really helpful and set the speakers up to demo them for us in store. They sounded crisp even at high volumes, so purchased them there and then. Great speakers and great service!

Rated 5 out of 5 by 3 Rex from Good quality speakers I was looking for a modern speaker , with a slightly less shouty sound to them , and having had KEF speakers before , and after some research , purchased these . Good decision . Great build quality, look good , and only take up a small area , and the sound reproduction is superb , acoustic, synth, rock, they handle anything , and fill a room 20 by30 foot , and beyond , with ease , powered by a NAD 3040 pe amp. Good stuff in this price bracket .

Rated 5 out of 5 by Tim Bruce from Opened up my music! Took delivery of these yesterday to replace my ageing Bose 301 speakers. Immediately it was a different soundstage altogether, with the detail and nuances of different instruments being immediately apparent. I'm hearing things in songs that I've never heard before. I've been a semi-pro musician for 40 years and these speakers represent the nearest thing to live music and 'being there' that I've ever listened to. Highly recommended. Combined with my other recent purchase from RS, the Quad Vena II, this is the perfect set-up for my listening requirements.

Rated 5 out of 5 by Stoke 69 from OMG Delivered today and wow the sound is crystal clear and dynamic.I purchased those solely on reviews as couldn't find any for demo. These suited my needs as there is no bass port on the back to anoy the neighbours but boy do they deliver.

Rated 5 out of 5 by Djsp01 from Well built, look amazing and sound great I've had these a couple of weeks and, WOW, I have a 500 watt sub also but to be honest I probably don't need it now. It's nice to have the ability of a REALLY deep rumble but if you haven't got a sub then you won't miss one. Nice separation and lovely sound. For the price I'm extremely happy. As I ordered these over the phone (lockdown) I didn't really want to collect them, this was no problem and they were delivered the next day for FREE!. Very helpful staff on the phone and I will definitely use them again. Thank you.
