Then I recommend these voice-matched "toppers" to experience overhead sound effects without having to install in-ceiling speakers. Each RP-500SA sits on top of a compatible Reference Premiere floor-standing or bookshelf speaker. An upward-firing 5-1/4" spun-copper woofer and 1" horn-loaded tweeter in each cabinet reflect sound off the ceiling for immersive overhead effects. Do you have an Atmos-capable receiver? Since these speakers connect to your receiver's "height" channels for power and signal, a home theater receiver with Dolby Atmos is required for operation.
