Frequently Asked Questions

Is QSC better than JBL?

As far as loudspeakers go, both brands are top-of-the-line for their respective genre. However, there are certain key differences that will affect the decision-making process. QSC is more budget-oriented with sound quality most similar to JBL’s First Edition speakers (SRX550/750).
On the other hand, JBL is more professional level but has an entry price point ($600 only one speaker) which puts it in competition with industry-heavy hitters like Bose and Klipsch (although some would argue they’re better than both of them). 

The decision ultimately comes down to what you’re looking for in advance cost vs complexity management; professionals typically choose JBL due to its intuitive software suite used with a pair of QSC speakers, but if you’re a DJ or hobbyist on a budget then the QSC K12.0 is your best friend with built-in Bluetooth support and woofer resonance control to make sure every note plays as clearly as possible at any volume without distortion.

What is the difference between QSC K12 and K12 2?

If plugged into the same outlet, the K12 2 is twice as loud as the K12. An additional benefit of this sound system is that you can toggle between an amplifier with twin speakers, or a single speaker with horn tweeter to optimize your space requirements. The K12 produces higher-pitched sounds whereas the K12 2 produces lower-pitched sounds.
A perfect example of when you might use these systems are for vocal music performances - where the performers are up close to each other and need everyone’s voice to be heard across long distances versus for performing woodwind pieces where everyone needs to hear every low pitched instrument in order not miss any subtleties in their playing. Obviously there are many factors that dictate how you will use either system but this gives you a good idea of the type of sound that each speaker is capable of producing.

Are QSC speakers good?

The short answer is yes. QSC shares the same philosophy as all of its competitors—to provide the best possible experience for your event. These subwoofers sound amazing with a good frequency response and directivity matched transition. In short, they are amazing speakers that even sound fantastic.
If you’re looking for an indoor speaker that offers total control, then the QSC K12 might be just what you need. What sets this speaker apart from competitors is that it doesn’t have a limited distance before you lose sound quality, so it provides reliable performance at any volume level. We also offer PowerPak™ technology so your speakers can survive multiple events without damaging their circuitry. When doubling up on speakers to save space, there’s no wiring required thanks to our Bluetooth compatibility and innovative porting system which routes sound around corners and over obstacles alike with ease.

How much does a QSC K12 2 weight?

It weighs just 17.7kg (39 lbs) which is lightweight compared to other speakers. It is one of the best speakers available right now in the market with durable speaker and great frequency range plus great sound quality for optimize performance.
