The RP-640D is the largest model in the Reference Premiere Designer On-Wall range, designed for rooms where floor space is at a premium but full-range performance is still required. It works as a left, centre, right or surround speaker.
A central LTS titanium Tractrix tweeter is flanked by two active Cerametallic woofers and four passive radiators, extending the low end to around 55 Hz from a slim cabinet. A tempered-glass base and keyhole mounts allow shelf or wall placement. Sold each, finished in black.
It is the on-wall speaker for installations where a slim profile is non-negotiable but thin sound is not acceptable.
