Seller's Description

Great 'budget' subwoofer from REL. I am the original owner and have used this sub primarily with music playback, but it also does a great job of pressurising a medium-sized room for HT duties. It complemented my Dynaudio bookshelf speakers (Focus 110) beautifully - could not have asked for a bett...

Our Thoughts RADAR AI

Timing matters here: this is an older REL HT-series sub, so value depends more on condition and the package than on age alone. At A$900, it lands about fair-to-slightly-ambitious against your local comparable set: below the A$1,043 median, but not by a huge margin, and comfortably within the A$892–A$1,267 middle spread.

For a buyer, the big checks are driver condition and amplifier health: make sure it powers up cleanly, stays quiet at idle, and delivers output without rattles, distortion, or auto-on weirdness. Also confirm the included cable, grille, feet, and remote/app controls if applicable, because missing accessories can make a “fair” sub feel overpriced fast.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About REL Acoustics

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.
