About the R-51M

The Klipsch R-51M is a compact passive bookshelf speaker designed for stereo hi-fi and home theater use. It uses Klipsch’s 90° x 90° Tractrix horn with a 1-inch LTS aluminum compression tweeter and a 5.25-inch copper-spun IMG woofer, giving it high efficiency and a lively sound character. It is rear-ported, has a black wood-grain vinyl finish, and is commonly sold as a pair. Sources show it was introduced in 2018 and is now listed by some retailers as an out-of-production or clearance model.
