Rel T/5x subwooferBought these in July of last year when I was running Dynaudio Special 40s. I've since upgraded to Totem speakers and prefer them without the subs.Happy to ship with pack-n-send at the buyers expense.Ad is for ONE SUBWOOFER ONLY
Condition is unknown, so this sits right on the fair side of the used market: the A$1,100 ask is just above the A$1,097 median and essentially level with the A$1,098 75th percentile, so it is not a bargain, but it is also not an overreach. In other words, the price is market-consistent for a clean example, and only a touch firm if there are any cosmetic marks or missing extras.
That makes sense for a well-regarded compact sub: the T/5x is prized for tight, musical bass, easy integration, and REL’s usual emphasis on speed over bloat, which suits small-to-medium systems nicely. The upside here is straightforward if it is tidy and complete—especially if the grille, cable, and footers are all present—because these tend to sell steadily when they’re clean and ready to drop into a system.
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.
