The powered speaker has become a staple for mobile DJs, musicians and AV professionals alike. The simplicity and scalability of these systems is the big draw. After all, what could be easier than just connecting the output of your DJ or live sound mixer directly to the speaker and turning everything on? For those who have been reluctant to join the powered speaker party because you felt that powered speaker amplification fell short of rack-mount amp quality, you are officially out of excuses.

There's a QSC amplifier inside each HPR! Now you can get the legendary performance and reliability of QSC's rack mount amplifiers built into a powered loudspeaker. The power module is designed with the same top-quality components and rigorous standards you expect from any QSC amplifier. QSC is regarded as one of the leading amplifier manufacturers in the world. We have over 35 years experience making professional-grade amplifiers. When you buy an HPR Series powered loudspeaker, you know it is backed by the QSC quality and reliability you've come to expect.

Many powered speaker amplifier modules use low-cost, consumer-grade "chip amps" to decrease costs and simplify design. The HPR Series features a professional, discrete component design, hardened to withstand abuse and engineered to deliver the best possible performance even when pushed to the limit.
