KLH R5100

The KLH R5100 is a home theater receiver. KLH sold it as part of a complete "Theater FM 5.1" package, which bundled the receiver with 5.1 speakers and a remote control and was pitched as a full home theater solution for budget-conscious buyers. The receiver handles Dolby Digital surround decoding and has AM/FM tuning. Inputs are a mix of digital coaxial and analog stereo RCA, for connecting DVD players, VCRs, CD players, and a TV. The manual runs 26 pages.

Documentation on this model is thin, and the power ratings conflict. The receiver is described variously as "100W," "100 watts per channel into 8Ω (stereo)," "5 x 100W," and, in marketing copy, a "500-watt dynamo." The most concrete figure appears to be 100 watts per channel into 8Ω in stereo. Without a manufacturer spec sheet to settle it, treat the numbers with caution.

What owners report is mostly practical. One forum user called it "a crappy KLH R5100" pressed into temporary service. Another bought one at 13 with $200 saved up. A Tom's Guide forum post notes the unit "only has coax digital audio in (optical is busted)," which suggests the optical input is a known weak point. A HifiShark listing shows one sold at $69 in June 2026, often without the remote. No production years, original price, or dimensions are documented anywhere in the record.
