Sunfire HRS-12 Subwoofer (Active / Powered) Saving up for another motorbike so some stuff has to go. These subs are very solid, hard to beat at this price. I have quite a few subs so will get by with some others, slumming it a bit. This one's manual says it goes down to 18Hz, so that makes it pretty much as good as subs get! Condition: Very Good Payment Method: eft, cash on pickup Region/State: (NSW) New South Wales/Australia By Spinnergeoff 0 Comments AUD $950 Date: October 24, 2025Oct 24
Very good condition makes A$950 feel fair-to-strong, not cheap, but still in the right zone for an HRS-12. This model earned a reputation for serious bass from a compact sealed cabinet, and reviews consistently praise its depth, speed, and output; one review even calls it a formidable subwoofer with outstanding sound quality, while another notes it can outperform much larger subs in perceived impact.
What makes it worth chasing is the combination of small footprint and real low-end authority: the HRS-12 is a 12-inch, 1,000 W design with extension around 18 Hz and a track record for clean, controlled bass in music and home theater. At this price, a clean, working example is a credible buy if it’s complete and the amp is healthy; just make sure the driver, controls, and auto-on behavior are all behaving as they should.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sunfire was founded in 1972 by legendary audio engineer Bob Carver in the United States. The brand emerged from Carver's unconventional approach to amplifier design, beginning with a graduate-school assignment to simulate earthquakes—a project that sparked decades of innovation in home audio. Headquartered in Petaluma, California, Sunfire is now part of Core Brands, a division of Nortek Technology Solutions that consolidates ten prominent audio and control brands under unified marketing and product development.
The brand has built its reputation primarily around subwoofers and power amplifiers. Sunfire pioneered the concept of true subwoofers in the early 1990s—compact, sealed designs with dramatically increased driver excursion that deliver powerful bass from remarkably small enclosures. The company's signature Tracking Downconverter power supply technology enables high efficiency and low distortion by dynamically matching output to instantaneous demand. Beyond subwoofers, Sunfire manufactures surround-sound processors, in-wall speakers, satellite loudspeaker systems, and premium home theater electronics.
Sunfire occupies the high-end segment of the consumer audio market, positioned for serious audiophiles and home theater enthusiasts willing to invest in performance. The brand's innovations—particularly compact, high-output subwoofers and efficient amplifier designs—have influenced industry standards and remain respected among discerning listeners. While not a household name like some mass-market brands, Sunfire maintains strong credibility within the audiophile community for uncompromising engineering and sonic performance.
