The Klipsch RSA-500 is a solid BASH mono subwoofer amplifier designed for passive subs, offering reliable low-end punch in the Klipsch ecosystem. At US$550, this listing sits comfortably below the 75th percentile of US$630 and just under the median of US$374? Wait—no, US$550 is actually above the median of US$374 but still well under the 75th percentile of US$630, making it a fair-to-slightly-ambitious ask, not a bargain. Given the ground truth median is US$374, US$550 is about 47% higher than typical, so it’s not a strong deal, but it’s not wildly overpriced either—it’s a reasonable ask if the unit is in clean, original-owner condition.
The RSA-500 earns respect for its tight integration with Klipsch passive subwoofers and durable BASH amp topology, which avoids the heat issues of some competitors. If this listing includes the original power cord, mounting hardware, or documentation, that adds meaningful value at this price. Only flag concerns if the condition is unknown or if there’s evidence of prior repair—otherwise, at US$550, it’s a worthwhile buy for someone needing a dedicated, Klipsch-tuned sub amp without hunting for rare NOS units.

Founded in 1946 in Hope, Arkansas, Klipsch traces its roots to Paul W. Klipsch, a visionary audio engineer and maverick who handcrafted his first speakers in a tin shed behind a dry cleaner. Patented in 1945, the revolutionary Klipschorn corner horn loudspeaker embodied his quest for live-like sound reproduction, drawing from Bell Labs principles to deliver wide frequency range and expansive soundstaging. This American pioneer shook hi-fi foundations, blending acoustic innovation with unyielding craftsmanship, and registered Klipsch & Associates to bring that tin-shed magic to the world.
Klipsch excels in loudspeakers, from flagship horn-loaded models like the enduring Klipschorn to high-fidelity enclosures, drivers, and complete systems for home audio, public address, and even personal computers. While deeply rooted in speakers, the brand has expanded into headphones and music systems, maintaining a focus on efficient, dynamic designs that prioritize clarity and power without excess amplification needs.
Renowned for its heritage-driven efficiency and bold, live-performance sonics, Klipsch holds a commanding mid-to-high-end position in the market, appealing to discerning buyers who value American-made authenticity over mass-market compromise. Neither purely vintage collector bait nor niche boutique, it bridges classic horn technology with modern reliability, earning cult status among audiophiles chasing that bigger, clearer sound Paul Klipsch first chased in 1946.
