Gemini Mk1 sub to let go at nominal sum.My latest speakers not really needing them, although saying that their prescence seems to add something. Additionally an XL200 mk11 in unmarked cherry to sell at say £100. I am situated in East Cheshire near M6. Too bloomin heavy to post.
£130 looks like a strong buy for a used Gemini in excellent condition. A new BK Gemini II was sold for £228 in 2015, and well-kept examples from a respected UK brand tend to hold value because they’re seen as musical, compact, and easy to integrate; at £130, this sits comfortably in bargain territory rather than merely fair.
What makes it worthwhile is the usual BK appeal: tight, punchy bass that suits both music and film, plus the kind of phase control and blend-friendly behaviour people like in this line. For a clean example, the main thing to verify is simple sub health rather than brand reputation — surround condition, cone integrity, and that it powers up and drives cleanly — but on price alone, this is the sort of listing worth moving on quickly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# BK Electronics
BK Electronics is a British manufacturer established in 1992, based in Essex and operating from a dedicated facility in Southend-on-Sea. The company was initially approached by REL Acoustics to design and manufacture subwoofers, a partnership that positioned BK at the forefront of home cinema subwoofer production. This manufacturing heritage remains central to the brand's identity and expertise.
The company specializes exclusively in subwoofer design and manufacture for home cinema and hi-fi applications. BK Electronics has built its reputation on direct-to-consumer sales, allowing the brand to offer competitive pricing while maintaining quality control through in-house British manufacturing. Their product range focuses on powered subwoofers engineered to integrate seamlessly with both dedicated home theater systems and stereo audio setups.
BK Electronics occupies a pragmatic position in the market as a value-oriented, specialist manufacturer rather than a luxury brand. The company appeals to discerning buyers seeking capable subwoofers without premium pricing, positioning itself between mass-market consumer electronics and high-end boutique audio brands. Their emphasis on domestic manufacturing and direct sales has cultivated a loyal following among UK and European audiophiles who prioritize engineering substance and manufacturing transparency over brand prestige.
