The Klipsch R-40M is the compact bookshelf speaker in the next-generation Reference series, sold as a pair. Each cabinet uses a single 4" spun-copper TCP woofer and a 1" LTS aluminum tweeter mounted to an all-new 90° x 90° square Tractrix horn, with a rear-firing port. Rated at 91dB in-room sensitivity and 8 ohms, it turns modest amplifier power into surprisingly big sound.
Why This Model Matters
The R-40M shows how Klipsch's horn-loaded, high-efficiency design lets a small cabinet punch well above its size. The larger redesigned Tractrix horn improves dispersion and imaging, while the TCP woofer tightens midbass. Its small footprint makes it easy to place on shelves, desktops, or stands, and it doubles neatly as a surround channel in a Reference system.
