REL Acoustics S/510 Subwoofer (Active / Powered) Hi, Price drop 13/9/24- Up for sale is the beautiful Rel s510 - purchased in Feb from Addicted to Audio. I am selling all my gear to make way for a kids home theatre room as I don't get to listen to music anymore etc etc Anyway ...... it is in near perfect condition, like all Rel subs or high gloss black items they are impossible to clean without slightly marking them . You can only see in a certain light/angle but a non issue - just how they are I have owned 3 in my time and all the same. Price includes shipping to anywhere in Australia - o
REL Acoustics S/510 subwoofers stand out for their big, bolder, and more “voluptuous” sound compared to smaller REL models, thanks to upgraded power and a 10″ active driver paired with a 12″ passive radiator. The asking price of A$3,280 is ambitious, clearly exceeding the 75th percentile of A$2,670 from 64 recent comparable AUD listings, where the median sits at A$1,140. This places the price well above fair market value for a used unit, suggesting buyers should only proceed if the condition is pristine or accessories are included.
Despite the high price, the S/510 remains a worthwhile buy for enthusiasts seeking high-end stereo performance with PerfectFilter circuits and deep low-frequency extension down to 20Hz. Its NextGen3 Class D amplifier delivers 500W RMS, and the original packaging and “as new” condition seen in similar listings add meaningful upside. If this listing includes original packaging or is from an original owner, it could offset the premium, but without such perks, the price feels risky compared to the A$3,000 deals currently circulating in Australia.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
REL Acoustics traces its origins to the inventive mind of Richard Edmund Lord, the man behind the brand's acronym, who founded the company in the United Kingdom around 1990 out of frustration with the subpar subwoofers available at the time. Dissatisfied with conventional low-frequency solutions, Lord crafted his own mammoth custom design, integrated into a bay window, which quickly earned acclaim from audiophiles as the finest they had encountered. This grassroots beginning in a tiny workshop marked the start of REL's relentless pursuit of audio perfection, evolving through innovations like the revolutionary High-Level Input that connects directly to a main amplifier's speaker outputs for seamless integration.
The brand specializes exclusively in powered subwoofers, eschewing amplifiers, speakers, turntables, DACs, headphones, or cables to focus intently on sub-bass systems. Early models like the Strata 2, Stadium, and Britannia range established REL's signature forward-firing designs and simplified crossovers, while later series such as T/x and the reimagined Serie S—launched in 2025 with models like the 212 Black Label and S/850—refine musicality, style, and power. Acquired in 2005 by John Hunter and Donald Brody, REL modernized its aesthetics and engineering without diluting its core philosophy.
REL commands a prestigious niche in the high-end hi-fi market as the preeminent authority on subwoofers, revered by discerning audiophiles for transforming even elite $15,000-to-$20,000 speaker systems into reference-caliber performers. Its boutique status stems from unwavering innovation and musical fidelity, positioning it as an essential upgrade for serious setups rather than a mass-market or mid-tier option.
