REL Acoustics Stadium iii Subwoofer (Active / Powered) Great condition subwoofer. plays well, easy to integrate and is musical, as most Rel subs are. I purchased this and the B1 after having 2 x 812 and also trying the Rel 212. I did not get on with either of the new models as I find the older Rel subs more pleasant to listen to, I summoned it was the older AB amps. Cheers Condition: Used Payment Method: EFT or Cash Region/State: (NSW) New South Wales/Australia By jackrinse 0 Comments AUD $550 Date: June 12, 20241 yr
The unknown condition on this REL Stadium III at AUD550 screams caution—it's a fraction of the typical used market median of AUD1,194 from recent comparable sales (25th percentile AUD945, 75th AUD2,388), making it look like a steal if it's solid. But without condition details, it's impossible to confidently benchmark; could be a bargain basement find or a basket case needing repairs that eat the savings.
Before biting, verify the amp's health—powered RELs like this often fail from overheated Class D modules or blown drivers, so insist on a full power-up demo with low-frequency sweeps for rattles or distortion. Check for the original power cord, Neutrik Speakon cable, and manual, as missing bits hint at hard prior use; age over 15 years amps capacitor concerns too.
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.
