KEF Q100 (Original Review)

What We Like

What We Don’t Like

KEF Q100 is a set of speakers that is almost too good to be true. If you are looking for a great set of speakers under $300, you will find these to be among the best currently available.

Design

When you first take a glance at KEF Q100, you will probably get a feeling that you are looking at much more expensive speakers. That feeling is perfectly justified as these used to be much more expensive not so long ago. The variant we are looking at today features all black vinyl exterior over quality MDF. The front baffle is made of durable materials and is bolted onto the cabinet.

In terms of aesthetics, KEF took a minimalist approach that panned out great. The only detail that breaks up the flat black baffle is a brushed aluminum bar with KEF’s logo on it. This bar separates the drivers from the front firing port, achieving a very attractive appearance. As you would expect, these come with a grille, which dulls down the design to a certain point.

In all fairness, these look much better naked. What is even more important is how well KEF Q100 are put together. Nothing rattles, nor will you have to deal with unusual vibrations.

Performance

The main benefit of having coaxed drivers in a speaker is how they react to each other. Instead of dealing with two axes of sound, you get all the sounds from one. Even so, Uni-Q drivers are definitely different from your standard coax. The trebles are not too bright, but rather comfortable to a point where you get a good balance. Mids are wide, open and very precise.

With that said, the main surprise comes when you start digging lower in the frequency range. The bass section on this speaker is impressive. That aluminum cone driver moves quite a lot of air. On top of that, the lows are clear and well defined. Combine this promising performance of the drivers with a simple but effective crossover, and you have a set of rather incredible speakers.

Q100 works much better for most people than the larger Q300. The main reason for this can be found in its vivid image that makes them sound bigger than they really are.

The Rumble

One of the rare opportunities to get a mid range set of speakers at a price that is within the realms of affordable. KEF”s Q100 are an absolute blast no matter how you look at them.
