KEF Q150 vs. Q350

Now, here is the real deal, the differences between these two speakers will help you decide on one of them. I will go through several aspects of the speakers and discuss the differences between both speakers. Let's get started with it.

Sound quality

When it comes to the sound quality of the speakers, there are hardly any differences you get to see there. The higher frequencies or treble sounds pretty much the same. They also use the same Uni-Q technology in bringing that unique tonal quality.

However, the difference in these speakers lies in the bass response. The Q-350 has a better bass quality than the Q-150. You get a pretty deep bass coming from the Q350. The smoothness in the bass is unlike anything else.

On the other hand, the lower frequencies on the Q-150 aren't as good as the Q-350. In reality, it can be a bit underwhelming at times as well.

So, when it comes to the sound quality, Q-350 will have the upper hand over Q-150 because of better bass quality.

Looks and build 

As for the looks, there is no difference between these speakers. You can even say that the Q-350 is just an upgraded model of Q-150 with the same eyes. You get the same color choices from both the speakers, and the design is also pretty much the same.

Now, the differences between these speakers come in their size. The Q-350 is comparatively more significant than the Q-150, which can decide for some. Because if you need a smaller speaker setup, then Q-150 will be your choice.

Another factor that differentiates these two speakers is the weight. The Q-150 is lighter than the Q-350. So, if you have to move around your speakers a lot, then Q-150 can be better.


Feature-wise, I don't think you will find a lot of differences here. But the only thing that sets them apart is the grille you get on Q-350. It gives the speakers much more security and keeps them clean for a longer time. Also, the durability of your speaker gets much better when there is a grille included on them.

Also, the peak power for the Q-350 is slightly higher than the Q-150, which brings out much more volume from the speakers. In short, you get louder sounds coming from the Q-350 over the Q-150.


This factor may impact how you choose to buy one of these speakers. Because there is a vast difference between the cost of both these speakers, however, before deciding on the cheaper one, make sure to justify the quality you get based on the price.

The Q-350 is much more expensive than the Q-150 while not having that many differences build and look-wise. So, you will mostly be paying extra for the better bass quality and some additional power.

Now, the question is whether it's worth the extra money or not. I have to say, if you want bass in your music and love to hear those low-frequencies popping off, then Q-350 will surely satisfy your more. Considering that kind of satisfaction, it's undoubtedly worth your money.

Still, if you are considering a speaker within a lower budget, then I would say Q-150 will be your choice.


All in all, it won't be an easy decision to choose between the KEF Q-150 vs. Q-350. When deciding between the speakers, it will mostly come down to the bass, size, and price.

If the bass isn't a big deal for you, then I would say you don't need to spend extra money on the Q-350. But if the bass is something you are looking forward to, I think Q-350 will be your choice regardless of how expensive they are.

Also, if you don't have too much space in your setup to accommodate the Q-350, then Q-150 will meet your needs.

No matter which one you choose, you end up with value for money. You will surely be satisfied with the performance you get from them depending on your pay. That's all there is to it.
