KEF Q550 Review

Are you looking to put the final touches on your surround sound system? Or are you simply looking for quality speakers to enhance your listening experience? Whichever it is, you can rest assured that the information in this review is just what you need. So let’s go through it and find out if these could be the next set of speakers you are looking for in my in-depth KEF Q550 review…


Who is KEF?

KEF is an acronym for Kent Engineering and Foundry. They are a market-leading electronics company, famous for constructing high-quality speakers. The company was first established back in 1961 in the UK, now with factories and shops right across the world.

KEF’s ground-breaking wireless speakers benefit from innovative Uni-Q technology, which is an instrumental part of their award-winning products.

The company was originally founded by Raymond Cooke because of his love for music and his refusal to accept second-rate audio products. Its mission is to deliver high-quality sound with as little interference as possible. They draw on 60 years of experience manufacturing products that are reliable, durable, innovative, and high-performance.

KEF Q550 – First Impressions

At first glance, this floor-standing speaker immediately pulls you towards its stature and tallness. It’s sleek, slim, and elegant like a supermodel, but not as high maintenance. This model is available in both black and white, which will seamlessly match the color scheme of your lounge or theater room.

My first impression is that two of them would look great as part of a surround sound home theater system. The stylish and statuesque nature of these speakers makes them a desirable addition to a pre-existing system that needs the finishing touches with their modern yet practical appearance.

KEF Speaker – Top Features

This award-winning floor-standing speaker comes equipped with all the accolades you would expect from a quality product. And it’s easy to see why.

The KEF Q550 speaker has lots of top features that make it a very desirable and attractive speaker. And if you have limited space, this is a great choice due to its slim design.

So, let’s check out the top features that make this award-winning speaker so desirable…

Uni-Q Sound Technology

The Uni-Q driver makes this an innovative and ground-breaking speaker. This KEF proprietary technology places the tweeter in the middle of the mid-range cone, which gives it depth and a 3D feel. Three-dimensional sound imaging is not something that standard speakers offer.

The ultra-wide sound dispersion creates a fuller listening experience. Uni-Q also works in tandem with a damped tweeter loading tube that dramatically improves the performance of the treble frequencies.

Q-Series Advanced Cabinet Enclosure Design

Do you know how important speaker cabinets and enclosures are? Even if you have top-notch tweeters and woofers, an inadequate enclosure or cabinet will render them useless. A good speaker enclosure can even make average speakers sound good. That’s how important it is. The Q-series advanced cabinet design takes the sound of this speaker to another level.

The Q-driver is placed in a closed box within the cabinet, giving it a double casing. The closed box was designed to reduce the load on the midrange cone. This increases clarity while creating a deep and punchy bass that rumbles in the middle of your chest.

Furthermore, this also elevates the midrange and enhances clarity via the mid-bass driver. The design of the enclosure also creates more natural bass frequencies.

Q-Series Woofers

The Q-series subwoofer features low-frequency drivers that have a larger roll surround. They also have a new spider suspension feature that helps to provide clearer bass at higher volumes.

However, it’s this new Q-series cone structure that increases the clarity of the midrange. You will also get better-controlled bass with the enhanced Auxiliary Bass Radiators (ABRs) that vastly improve surround sound and rear suspension.

These key features of KEF Q550 speakers are only found in KEF models and make this speaker one of the most popular speakers for home theater aficionados and audiophiles.

Speaker Build and Specifications

The modern, stylish, and contemporary look and feel of this KEF speaker is a major selling point. The entire build, specifications, and dimensions are built for convenience and practicality, while the floor-standing speaker design is perfect for space management.

I also love how some of the interior screws for the tweeters and cones are hidden. Plus, the adjustable “feet” stands have spikes on the end that can be easily adjusted to for any height you need. These are a great feature if you have uneven floors.

The exterior design is also very modern and elegant, ensuring it fits in with most living room or theater room interior designs. Here is an exact list of the specifications.

  • Enclosure Type: Cabinet and close box enclosures.
  • Frequency Response Range: 58Hz to 28000Hz.
  • Power: 15 to 130 Watts.

KEF Q550 Review – Pros and Cons


  • Cozy and compact speaker size that is geared to space management.
  • Elegant, sleek, and slim tower design.
  • Innovative woofer and double bass radiators ensure bass is deep yet smooth.
  • Exclusive Uni-Q Sound features.
  • Wide sonic image.
  • The closed box midrange cabinet reduces load and distortion.

  • These speakers are sold separately, not in a pair, so you will need to order two.

KEF Q550 Review – Final Thoughts

If you are looking for a practical addition to your home theater system, this is a great speaker. Especially if you have limited space and need a slim and sleek speaker design, but it’s not just the design. These speakers look stylish and come in either black or white. And as for the sound, the built-in Q-Series Sound Technology also creates stunning and undistorted bass depth.

Is this the best floor-standing speaker on the market? Probably not, but it is a high-quality product that looks good, performs well, and represents fantastic value for money. I, therefore, think it’s a great option for a lot of buyers.

Until next time, happy listening.
