REL T9i Boxed with all accessories and instructions
New, the REL T/9i was around £899–£1,000, so £500 for a good-condition example is a strong used buy—roughly half original retail and comfortably below what a clean, properly working unit should command. It is not an absurd bargain, but it is clearly attractive if the listing is accurate.
The T/9i earns its reputation with fast, well-controlled bass rather than merely making noise: its 300-watt Class AB amplifier, 10-inch active driver and matching passive radiator deliver substantial depth while retaining useful timing and texture. It integrates especially well with capable floorstanders and suits medium-to-large rooms. Check that the Neutrik high-level lead is included, along with the original feet and grille, and confirm there is no hum, rattle or damage to the passive radiator; otherwise, at £500 this looks like a buying opportunity.
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.
