Notable mainly as a serious, purpose-built subwoofer amplifier rather than a glamorous standalone component. At US$129, this is a strong bargain: it sits well below the US$240 25th-percentile comparable price, against a US$300 median and US$400 75th percentile. Assuming the listing’s tested-working claim is accurate, the price leaves substantial room for a worthwhile project or replacement amp.
The Gold PowerSub platform was respected for deep, controlled bass, and its dedicated amplifier was built around a substantial 15-inch design with roughly 250 watts in the earlier version. It makes sense for restoring a Triad subwoofer or building a custom bass system where the matching crossover and connections are useful. Before buying, confirm the exact connector layout, input-level compatibility, mounting dimensions, and that “tested working” includes sustained output without hum, distortion, or intermittent shutdown. Older Triad units can be rewarding, but at this price the risk is modest.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Triad: Heritage and Positioning
Triad was founded in 1981 in Portland, Oregon, where it remains headquartered and manufactures its products today. The company has built its reputation over more than four decades as a specialist in custom audio solutions, hand-crafting speakers to order in its own factory using eco-friendly processes. This commitment to domestic manufacturing and bespoke production has become central to Triad's identity in the premium audio market.
The brand's product portfolio centers on architectural and custom installation speakers, encompassing in-wall, in-ceiling, in-room, and on-wall loudspeaker designs tailored for residential applications. Triad has expanded significantly in recent years, introducing amplifiers, home cinema speakers, and subwoofers alongside its core speaker offerings. The company has also established itself as a pioneer in immersive audio technologies, delivering solutions optimized for Dolby Atmos, DTS:X, and Auro 3D formats—positioning it squarely in the high-end home theater and whole-home audio segment.
Triad occupies a luxury tier of the audio market, distinguished by its emphasis on design aesthetics, sonic performance, and customer service. The brand targets custom integrators and discerning residential clients seeking premium, visually integrated audio solutions rather than traditional component-based systems. Its hand-built manufacturing process, American production, and focus on bespoke customization reinforce its positioning as a high-end boutique manufacturer rather than a mass-market player, appealing to audiophiles and integrators who prioritize craftsmanship and tailored solutions.
