Sunfire Redesigns HRS High Resolution Subwoofer Line

PETALUMA, CALIFORNIA, August 6, 2015 – Industry-leading luxury subwoofer and home theater audio brand, Sunfire, today announced the redesign of its widely popular, high-performance HRS Subwoofer series. Delivering a dramatically improved listening experience and a boost of serious power, the HRS Subwoofer series builds upon legendary Sunfire technologies to deliver the best and boldest sounding subwoofers from small but stunning enclosures.

“The HRS Subwoofer series is at the heart of the Sunfire experience,” Core Brands Audio Marketing Manager Matt Dever stated. “With the help of our Furman power engineering team, we’ve added a new Toroidal Transformer for dramatically reduced noise levels, and improved listening experience for everyone to enjoy.”

Sunfire HRSAvailable in 8, 10, and 12-inch models, the HRS series is the perfect option for any size home theater or audio system. Sunfire’s innovative Frequency Filtration Design™ (FFD) acoustic tailoring technology greatly improves accuracy even at the highest volumes and lowest frequencies. The FFD™ also gives HRS subs a remarkable ‘sonic intelligence’ that lets the listener clearly hear and feel all the deep-bass details in their favorite music and movie soundtracks.

Creating breathtaking power with crystal-clear sound, the subs feature a built-in 1,000-watt amplifier and advanced driver technology. All three subs in the HRS series deliver 1,000-watts RMS of power courtesy of Sunfire’s exclusive Tracking DownConverter™ amplifier design. This delivers high levels of current with far greater efficiency than conventional amps, for huge, pure power reserves with minimal physical size and cool-running operation. Additionally, the new standby circuitry reduces standby power consumption like never before. If that weren’t enough, the amp’s soft-clipping circuitry also keeps the woofer from being dangerously overdriven or producing obvious distortion, without squashing the dynamic subtleties or compromising its impact during big action flicks.

Much of the HRS series’ powerful performance comes courtesy of the massive, extra-long-throw woofer. The woofer’s ability to make extremely long excursions enables it to displace large amounts of air, producing deep, bone-rattling bass. The driver’s large, specially designed surround holds the woofer cone precisely in place as it moves, for the most accurate sound possible.

For easy-installation and convenience, the HRS provides multiple connectivity options, including RCA inputs/ outputs, speaker level inputs, detachable power cord and international voltage selection for increased installation flexibility with consumer and professional components. This allows the HRS to fit seamlessly into new audio designs as well as existing configurations. Furthermore, line-level inputs and outputs, plus speaker-level inputs let you easily connect this sub to most audio systems, and its variable back-panel volume, crossover, and phase controls help you fine-tune the bass to any particular sound.

To round out the impressive offering, the HRS offers a collection of premium audiophile features like auto turn-on circuitry, gold plated connectors, soft clipping circuitry, variable crossover level and variable phase control. “The Sunfire HRS subwoofer is designed in an effortlessly stylish, high-gloss piano black finish that fits flawlessly into almost any room d├ęcor, making it the perfect foundation for every great home theater and audio system,” Dever concluded.

The HRS subwoofers quality control levels have been raised to the highest in Sunfire’s history. HRS subwoofers are available now through certified Sunfire dealers and distributors.
