3 Things You Didn’t Know About SpeakerCraft® HRSi Series Subwoofers

July 7, 2021

We are stoked to announce the latest line in our stellar subwoofer series – the HRSi.

The HRSi series of subwoofers have been crafted for high-end balance and peak performance. While the SDSi series can be viewed as an entry-level line for customers looking for the most boom for their buck, the HRSi line of subwoofers are built for the audiophile looking for studio-quality acoustics. The greatest differences over our previous SDS series are the addition of a second passive radiator, more power, and an optional subwoofer wireless kit. These are great multi-purpose subwoofers available in sizes from 8”, 10”, and 12” to satisfy audiophiles looking for reference sound. Each of these home audio subwoofers house a powerful single active driver for deep bass and incredible sound. Each HRSi subwoofer offers up to 1000 watts of amplifying power, giving your sound system an extra kick.

To celebrate the launch of this amazing new subwoofer line, here are 3 interesting facts about the SpeakerCraft® HRSi subwoofer series:

They actively bring the BOOM

Sound quality is great for movies and music and has the “grunt” to keep up with the harshest demands from a movies’ LFE track. And remember, two are always better than one. With two of our HRSi series subwoofers hooked up to your sound system, enjoy more realized sound and louder BOOMS than ever before.

They’re built on the legacy of the Sunfire® brand

Since 1994, Sunfire® speakers have been a disruptive force in the speaker industry, combining unconventional thinking with precision engineering to deliver the best audio performance possible. Each of the new SpeakerCraft subwoofer series is backed by the legacy and incredible technology of Sunfire products – with a few notable improvements. We have added more power, an updated industrial design with rounded corners and kept the signature 5-layer piano black lacquer finish. Performance is greatly improved due to a more powerful DSP and setup is further simplified via a smartphone app that allows for complete configuration and even includes app-based room correction.

Their high back EMF driver design

In a bit of design genius inherited from the Sunfire brand, the SpeakerCraft HRSi subwoofers include high back EMF technology, which allows for massive amounts of deep bass from a smaller-sized cabinet. This works by having an ultra-strong fiberglass cone with a huge motor structure to battle the pressures of small enclosures and their impact on the excursion of the woofer. Essentially, this allows for more booming bass in a smaller box.
