Design of QSC K12.2

It is a strong and durable speaker cabinet that can handle tons of abuse. Its design is very professional and the appearance is clean.

It has an angular design that will let you use the K12.2 not just as the main output speaker but also as the floor speaker.

You get a lot of elasticity by purchasing this speaker set and can use it for several purposes. You can also mount this speaker in multiple positions or just set it up on your shelf just the way you like it.

Frequency response

The frequency response of this speaker is from 50 Hz to 20 kHz that is also very sufficient and dense.

You will have enough frequencies to operate which can be heard by a human ear.

The sensitivity falls at 126 dB and the speaker will reach a high volume without having to put too much effort into it.

At a high volume, the sound remains very clear and accurate without even a bit of distortion.

Sound Quality of QSC K12.2

The quality of sound is very essential when purchasing a powered speaker. And the QSC K12.2 Powered Speaker marks this area with the storm.

The mids and highs of this speaker are extremely pure and it is also capable of covering an area of 75-degree even field. It makes sure that you’ll be able to lead your sound evenly through medium or small-sized space.

In any case, if you want to cater to the requirements of bigger venues, the speaker can always be combined with a subwoofer or an extra speaker to offer you the level of volume which you want.

As far as the bass is concerned, it provides reasonable bass which is more than enough for smaller gatherings.

However, in bigger setups, you’ll have to pair it up with a subwoofer to get the most out of it.

Another thing which we would like to mention about this speaker is that the sound of the music is never going to irritate you.

We have come across a lot of powered speakers and in every one of them, the sound would start irritating you after a while but not anymore.

Build Quality

This company designed this speaker while keeping professionals in mind. That’s why it has an exceptional build quality.

It comes with an impact-resistant ABS core along with cloth lining on the front grille which keeps this speaker protected at all times. It has handles that are made of aluminum which can make them simpler to transport.

The key reason why so much thought was put into making this speaker fall-proof was that QSC knew it would be moved from one place to another a lot.

They wanted to ensure that the speaker does not sustain damage during transportation.

This powered speaker is highly durable but we should still tell you to handle this QSC K12.2 speaker with utmost care.

This speaker is also backed by a 6-year warranty that is good and has a very lightweight body that makes it simple for the user to move it from one place to another.


This QSC K12.2 powered speaker is an incredibly powerful and capable speaker. This 12” speaker has 2000-watts of power which will deliver up to 132 dB at 1m which is enough to handle clubs, outdoor live events, and live shows you want to play.

Whether you are a DJ, band, or public speaker, this speaker packs tons of power for clearness and volume.


With the 2 XLR line-in port and 2 XLR line outputs, you will be able to connect your soundboard, or different boards, and send them out to others speakers in the line. In addition, there is a “MIX” output of all 3 channels which does not contain any DSP processing.

Tunning Options

It has included a selection of useful and functional options for tuning.

There is an onboard LCD screen through which you can navigate by using a dedicated dial and 2 additional buttons.

It is very easy to use which means you won’t need to reference the manual every time you need to make a change.

This also allows you to choose from a variety of presents like “Dance” for enhanced bass.

You can fine-tune these to your personal preference or situation. For instance, you can change the delay if you have an enormous speakers’ setup throughout a hall.

The removal of the “Deep Bass” preset is a notable change that was present in the previous generation. That preset helped ramp up the lower end.

The other best feature is the ability to save Scenes and you can load the same scene if you’re ever playing in the same location.

It saves time when setting up for a performance and you can also lock these settings as well to avoid others from fiddling with your preset.

It has a 3-channel mixer for those who don’t already have a dedicated mixer board. While basic this does do what you want.

Having the option to balance the mic input with an instrument without a dedicated mixer is a better touch for those who are on a tighter budget.


The powered speakers are like the best monitor speakers where there is a huge difference of price between several models.

This 12” powered speaker is on the higher end of the price scale compared to other brands in the same space.

But the speaker quality does provide excellent value for the money.


Are QSC speakers any good?

These speakers sound great; clear, rich with a nice low end, prominent, and smooth highs… they are reasonable in terms of weight, and a single person can easily mount them on tripods.

Final Thoughts

The QSC K12.2 Powered speaker is a great speaker which is going to pump up the stage at a party but it does have a higher price tag. If you happen to be a DJ who needs to improve his moving setup and is searching for something lightweight, one which can be tuned best, then going for this speaker will be a very wise choice.

It provides great clarity and a better range of input options and it is extremely lightweight and very strong.

It is a perfect speaker for those who are looking for a dependable speaker set.
