The Klipsch Rp-600M Ii is the flagship bookshelf in the Reference Premiere Ii series. A larger 6.5-inch Cerametallic woofer delivers deeper bass and higher output than the Rp-500M Ii, while the new 90-by-90 hybrid Tractrix horn widens the sweet spot so the stereo image fills even large rooms. Magnetic grilles, heavy-duty binding posts, and a premium ebony vinyl finish make this a reference-grade pair for any two-channel or home theater rig.
