USD 499 is fair market for this compact 8-inch sub. The OmniSub 8 is a solid entry-level powered subwoofer with a 200-watt Class D amp, 8-inch long-excursion driver, and response down to 32 Hz. Used examples typically move in the USD 450–550 range depending on condition and age, so this asking price sits right in the middle—not a steal, but not inflated. For a compact, unobtrusive sub that handles both music and home theater competently, it's reasonable.
Before closing, confirm the unit powers on cleanly and that the Class D amp runs cool without audible noise or humming. Check all controls (volume, crossover, phase adjustment) respond smoothly, and verify both line-level and speaker-level inputs work. These amps are reliable, but verify the long-excursion driver cone shows no tears, dust-cap damage, or signs of hard use. Ask the seller about its history—how long they've owned it and whether it's seen heavy use or been in a climate-controlled environment. Original packaging and documentation are a plus but not essential for a used unit at this price.
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.
