QSC HPR153I Details top
The HPR153i 3-way loudspeaker is a great choice when the warmth, clarity and projection of a horn loaded, cone midrange system is desired. The 15" driver and larger enclosure volume provide extension down to 36 Hz making the HPR153i well suited for reinforcement of music with lots of low frequency content. Mids are handled by a 6" cone driver that seamlessly covers the critical vocal region. A 1.4" (diaphragm) compression driver delivers brilliant top end response. The 600 watt (400 LF / 100 MF / 100 HF) power module includes a 100 Hz high-pass filter (HPF) for use in subwoofer-equipped systems.

The new HPR Series offers performers the power, technology and legendary reliability of QSC amplification combined with the simplicity and convenience of powered loudspeaker systems. Whether your application is vocal reinforcement, dance music or full-tilt rock and roll sound, there's an HPR speaker configuration for you.
Why choose powered loudspeakers?
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.
Why choose QSC's HPR Series?
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.
Discrete component designs
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.
Signal Processing
An advantage of powered speakers is that the design engineers know everything about the system. This means that all the signal processing - crossover frequencies and slopes, EQ transfer functions, phase corrections and limiting - can be precisely tailored.
Multi-Band Limiting
Nothing kills speaker drivers faster than clipping, which happens when an amplifier is driven too hard. At best, this clipping will be annoying to listeners. At worst it may burn up the speaker voice-coils.
The HPR series protects itself (and your performance) through the use of active Multi-Band Limiting that detects excess level at each amplifier channel before clipping occurs. Then dynamic peak limiting is applied to the overall signal. The limiting parameters have been carefully set to maintain overall frequency balance and minimize audible "pumping". You will probably need to watch the rear panel LIMIT LED to even know that limiting is taking place. The result - your HPR system delivers clean, undistorted sound even when you push it hard.
Cross-over
The bi-amplified HPR152F and tri-amplified HPR153F are "active" systems. There are two advantages to an active system.
Advantage 1:
With a conventional passive speaker system, a single amplifier channel covers the entire frequency spectrum. So, when a bass note overdrives an amplifier, the resulting clipping produces harmonics that also go to the mid and high-frequency drivers. The result is audible distortion or, worse yet destruction of the drivers. In bi/tri-amplified systems, only the low-frequency amp would produce distortion while the mid and high frequency amps continue to deliver clean, undistorted sound.
Advantage 2:
Active systems allow far more extensive tailoring of the cross-over response than is possible with passive cross-over networks. The two and three-way HPR models include crossovers that maintain coherent performance across the transition between low, mid and high-frequency drivers.
In addition, these models incorporate a unique, 100 Hz Low-Cut filter. This opens up powerful mixing possibilities.
One subwoofer or many, the HPR subs have crossover functions for any application. The subs' stereo inputs sum the left and right inputs to mono while also giving you a stereo output for a pair of mid-high speakers.
Professional Good Looks and Tour Grade Tough
Rugged 13-ply birch enclosures
The HPR Series loudspeakers are meant to travel and are constructed of premium quality 13-ply birch coated with a tough, professional sprayed finish. Carefully engineered bracing keeps the enclosures rigid for tight, accurate low-frequency performance.
Tour-grade 16-gauge steel grilles
The attractive, powder coated 16-gauge steel grille is built tough to withstand anything that you can throw at it. If you look closely, you can see the slight concave shape of the grille which goes even further to keep it rigid.
Amplifier module
The amp module is constructed using a large heat sink with ample radiating surface so your HPR speakers won't shut down just when the show gets hot. Another example of QSC's attention to details is the beveled edges of the heat sink fins. Sharp edges have been milled off to prevent injuries to users and their gear.
Transport
Rolls with the greatest of ease
Heavy duty 3" wheels on the back of the HPR181W roll easily over cables, thresholds and other obstacles.
Ergonomic handles with comfortable non-slip grip
QSC designed and tooled an ergonomic handle with a comfortable, no-slip grip. Every time you pick up your HPR speaker, you'll be reminded of QSC quality and attention to detail.
Leave the light on... or off
With the HPR Series, you have the option of turning the grille-mounted LED off for situations where it would be distracting.
Going that extra mile
Before any QSC product gets its final approval, it has to pass a multitude of grueling tests. If we can find a way to break it, we will and we'll engineer a fix so it doesn't happen to you. That's what going the extra mile means, more testing, better quality components and a commitment to making the best products possible. Professionals rely on QSC gear every day because it doesn't let them down.
HPR Series Powered Loudspeakers are eligible for QSC's Free 6 Year Extended Warranty (a $99 value). You must register your products on the website to qualify.
