RPA60BT Home Theater Bluetooth Receiver + (4) 8" Black In-Ceiling Speakers + Sub

This system pushes home theater performance to another level by pairing four 8" ceiling speakers with a dedicated 8" powered subwoofer and a 1000W Bluetooth receiver. The HC85 speakers already reach down to 40 Hz on their own, delivering 240W RMS per pair through polypropylene cones with rubber surrounds. Adding the Rock Shaker 8 subwoofer (200W RMS, Class D amplifier, tuned MDF enclosure) layers in tight, controlled bass from 20 Hz, giving movies and music physical impact that ceiling speakers alone cannot fully deliver.

Each ceiling speaker installs flush through a 9.3" cutout at 3.03" depth with paintable grills and aim-able swivel tweeters. The subwoofer connects to the receiver's dedicated sub preamp output, with adjustable volume, crossover, and phase controls for precise blending. The receiver supports Bluetooth, USB, FM, optical, coaxial, and RCA sources plus a karaoke mixer with echo control. Place the sub in a corner or beside furniture to maximize room reinforcement, and let the four 8" overhead speakers handle the full mid and high frequency range. This is a complete home theater solution for large rooms, media rooms, and spaces where both hidden overhead audio and serious bass are priorities.
