Let’s Compare These Beasts / Is one better than the other?

Comparing KEF Q150 and KEF Q350 isn’t the easiest thing in the world, and that can be the reason why I’ve chosen to divide this part into sections. You will find some comparisons regarding the design, connectivity, and performance.

Let’s see!

Design / Appearance

In general, both KEF Q150 and KEF Q350 look almost the same. The main difference is that KEF Q150 is bigger when it comes to size measurements. The colors that these pairs of speakers come with are black, walnut, and white. Based on the colors, they are very good-looking, and they bring a minimalist look to the whole place that you put them.

These speakers are very durable, and they are the ones that can be used for a pretty long time.

Is there a winner?
As I mentioned, these speakers are pretty similar to one another and that can mean one thing. We have a win-win situation when it comes to the design part. Anyways, if you are into bigger speakers then the winner becomes the KEF Q150.

Setting Up / Connectivity

We all know that the connections of any device are the most important things that should be considered. Now, these speakers have the same connection and the same ports.

On the back of the speakers, both KEF Q150 and KEF Q50, are placed two main ports that are in charge of the connectivity. Once connected, you shouldn’t worry at all because the connection is super sturdy.

The maximum output of KEF Q150 is 108dB meanwhile KEF Q350 goes a bit higher at 110dB.

Based on the fact that these speakers come as pairs, it is important to mention the crossover frequency, and on KEF Q150 and KEF Q350, it works at 2.5kHz.

There’s an important thing that unites these two types of speakers. It is the Uni-Q Driver which is a very famous array that is made and specialized by KEF, and it is the combination of the midrange and the woofer, in order to avoid driver interference.

Is there a winner?
The connection part of these speakers is the same so here there is not a specific winner. Both of them know how to shine in the connectivity part.

Sound Quality / Performance

KEF is one of the brands that bring an amazing sound quality to everyone that chooses their speakers. Now, when it comes to differentiating the speakers from one another, there are some important things that should be mentioned.

KEF Q150 speakers are one of the most powerful speakers and they are also known as a powerhouse. They are able to bring to you a frequency range of 51Hz to 28kHz and whenever you use them you will notice that the sound comes super clear.

The KEF Q350 on the other hand works with a frequency range from 63Hz to 28kHz, and that doesn’t mean that the sound is muffled or anything like that, KEF Q350 speakers are shining speakers when they deal with bass.

Is there a winner?
Even though the speakers are pretty similar and work with almost the same technologies, the difference in the frequency response makes the KEFQ 150 a bit better since it covers a wider range.
