At €350, the listed REL Q201E is a genuine bargain compared to the typical used market, where this model often trades between €400 and €500; new units historically cost around €700–€800, making this asking price roughly 45% below original retail. The listing sits well below the 25th percentile of used pricing for this sub, signaling a strong deal for a buyer who moves quickly.
The Q201E is well-regarded for its tight, musical bass and 200W class-D amp that delivers clean output without distortion in small to medium rooms. Its compact 10″ design fits easily in living spaces while still providing impactful low-end extension down to 28Hz. At this price, even with unknown condition, the upside is significant—this is a rare opportunity to own a respected, high-performance sub at a fraction of its former value, and any minor wear would be easily outweighed by the savings.
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.
