Theater Solutions 4R4S Sandstone Rock 4 Speaker Set

Outdoor Rock Speaker Set

The Theater Solutions 4R4S system includes four passive sandstone speakers built for permanent outdoor installation. Each unit houses a 4.5 inch poly mica woofer and a ferro-fluid cooled soft dome tweeter angled twenty degrees upward. The cabinets use multi-layer composite construction with silicone sealing and rust resistant steel grilles. They connect to any home audio receiver or amplifier delivering ten to one hundred twenty-five watts per channel at eight ohms.

Wired Installation Kit

Speakers arrive with four inch lead wires ready for direct splicing to CL3 rated raw cable. Runs under forty feet use sixteen gauge wire while longer runs require fourteen gauge. No wireless pairing, batteries or proprietary connectors are involved; the system relies entirely on the amplifier you already own. An instruction manual guides the straightforward wiring process for each of the four rock enclosures.

Coverage And Limits

Frequency response spans eighty hertz to twenty kilohertz with ninety-four decibel sensitivity, providing clear background music across patios, pool decks and garden areas. The passive design means output ceiling is fixed by the connected amplifier's power rating. Buyers needing wireless streaming, battery operation, sub-bass extension below eighty hertz or more than four zones will find this set does not meet those requirements.
