RPA6000USB + REQ42-B + HC85 + APM10B

This four-piece system brings together a 1000W Bluetooth receiver, a 42-band equalizer, a pair of 8" in-ceiling speakers, and an 8" powered subwoofer for a complete home theater solution that covers the full frequency range. The RPA60BT V2 receiver provides Bluetooth streaming, USB playback, optical and coaxial TV inputs, FM radio, and a karaoke mixer with two mic inputs and echo control. Its dedicated sub output feeds directly into the Rock Shaker 8 subwoofer, and the preamp output lets you expand with an additional amplifier or powered speakers later.

The REQ42-B equalizer sits between your receiver and speakers, giving you 21 bands per channel with blue LED indicators for fine-tuned room correction. The HC85 ceiling speakers handle mids and highs with 8" polypropylene cones backed by 20 oz. magnets, producing 240W RMS per pair with a frequency response that starts at 40 Hz. Aim-able swivel tweeters direct highs to your listening position, and paintable grills keep everything flush and hidden. The Rock Shaker 8 subwoofer fills in below that with 200W RMS from its Class D amplifier, a rear-ported MDF enclosure, adjustable crossover frequency, and a phase switch. Between the large ceiling drivers and the dedicated sub, this system delivers deep, impactful bass that smaller setups cannot match.
