The Sharp HT-SPR52021-BK is a pair of wireless rear speakers for soundbar owners who already run a Sharp Q Series bar. Each cabinet holds two drivers: one aimed at you for surround, one aimed at the ceiling for Dolby Atmos height. The pair adds two surround channels and two height channels, taking a 3.1.2 HT-SBW53121 to 5.1.4. Sharp rates them at 66 W RMS (2 × 18 W surround plus 2 × 15 W height), with a 200 W peak figure on the box.
Sharp's manual lists two compatible soundbars: HT-SBW53121 in black or silver.
Dolby Atmos speakers that immerse you in the heart of the action.
Most Dolby Atmos speakers in a living room sit at the front, inside the bar, so the overhead layer arrives from in front of your face. That works for a jet flying away and much less well for rain or a room tone meant to close in around you. This pair moves two up-firing drivers behind the seating and bounces them off the ceiling. Frequency response runs 100 Hz to 20 kHz. Everything below 100 Hz stays the subwoofer's job, which is how a rear channel should be built.
Wireless means no speaker wire, not no power cord: each speaker needs its own outlet and draws 25 W. Pairing is manual and happens once: hold PAIR on the back of a speaker for three seconds until the indicator flashes, then select WLPAIR in the soundbar menu and wait about five seconds for PAIRED. Sharp asks for at least 50 cm of clearance below the ceiling and at least 1 m between each speaker and where you sit.
Each cabinet is 4.6 by 9.4 by 4.4 inches and stands on a removable plastic stand, so a shelf or side table works out of the box. Wall-mount fixings are included: a 1/4-20 screw into a 17.4 mm hole, and the stand comes off before mounting. If the couch is not sitting 1.5 m from both rears, the soundbar's SPKVOL menu trims each speaker from −5 to +5.
