At US$450, this Klipsch RSA-500 Subwoofer Amplifier sits comfortably above the median of US$374 but remains well below the 75th percentile of US$637, making it a fair used-market price rather than a bargain. It is not ambitious given the strong 110-listing dataset, where the 25th percentile lands at US$243, so you are paying a sensible premium for what appears to be an unknown-condition unit in a solid mid-range position.
The RSA-500 is a respected BASH amp delivering 300 watts RMS into 8 ohms and 500 watts into 4 ohms, capable of powering up to two passive Klipsch subwoofers with both line and speaker-level inputs. Its black brushed-aluminum build and original US$1,249.99 new price underscore its value even at this asking price, especially if the unit is original-owner or includes the power cord. With no known material failure points specific to this model, a clean listing at US$450 represents a genuine buying opportunity for enthusiasts seeking reliable, high-power sub amplification.

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.
