€399 is ambitious against the recent used market: with a median at €222 and a 75th percentile at €366, this listing sits above the usual range and asks a premium. That doesn’t make it a bad sub, but it does mean the buyer should expect something genuinely special in condition, presentation, or included extras to justify the gap.
That said, Energy’s powered subs are often liked for lively, punchy bass and easy integration in a modest stereo or home-theater setup, so the appeal is real if you need compact low-end support. If it’s genuinely clean, fully working, and comes with the original lead or remote if applicable, it could still be a sensible buy for the right system — just not an obvious bargain at this asking price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Energy Speakers emerged from Canada in 1973, rooted in a commitment to scientific loudspeaker engineering. Born from participation in the National Research Council of Canada's extensive study from 1977 to 1986, the brand quickly established its heritage with the iconic Energy Pro 22, a design that set benchmarks for accuracy and became a staple, evolving into the Connoisseur and Reference Connoisseur 22 lines. This foundation of research-driven innovation has defined Energy's unwavering pursuit of audiophile-quality sound reproduction.
The brand focuses squarely on loudspeakers, delivering categories from high-end Reference Connoisseur series to value-packed C-Series and RC-Mini wood-cabinet models. It has expanded into powered solutions with the Energy Power Series, including the pioneering Power Bar soundbar, which integrates seamlessly into modern systems without a receiver. While not delving into amplifiers, turntables, DACs, headphones, or cables, Energy prioritizes speakers renowned for sonic precision and spatial drama.
Positioned as a mid-tier contender with premium aspirations, Energy holds strong appeal among discerning buyers seeking powerful, accurate performance at accessible prices. Acquired by Klipsch Group in 2005 alongside Mirage, it maintains a reputation for reliability and value, backed by decades of critical acclaim in the competitive hi-fi market.
