Outdoor audio that survives the desert.
Coastal Source is the only outdoor audio and lighting brand we specify for Arizona installations. The cabinets are sealed bronze, the connectors are watertight, the cabling is direct-burial copper, and the wiring is calibrated for outdoor runs that span pool decks, courtyards, and outdoor living rooms. Two decades after install, a Coastal Source system still sounds like the day it was commissioned. Nothing else in the outdoor category comes close.
Engineered for harsh environments.
Coastal Source originated as a marine-grade outdoor audio brand for coastal estates that have to survive salt air, hurricanes, and constant moisture. The same engineering carries over beautifully to Arizona, where the enemy is UV, heat, monsoon dust, and 115°F summers. Every cabinet is sealed bronze. Every connector is corrosion-proof. Every cable is direct-burial. Coastal Source outdoor speakers in Scottsdale routinely outlast indoor consumer speakers — not by a margin, by a multiple.
The Bollard system — the design integration.
Coastal Source's signature product is the Bollard outdoor speaker system: a sealed bronze cylinder, available in patina finishes, that distributes high-fidelity sound across a patio or pool deck while doubling as landscape lighting. The speakers blend so naturally into the hardscape that guests assume they are decorative bollards — until the music starts and the sound surrounds them from every direction.
A complete outdoor system.
Coastal Source designs the whole outdoor audio ecosystem: bollards, in-ground subwoofers, marine-grade architectural speakers, integrated landscape lighting, and the cabling and connector system to tie it all together. Every Beyond Audio outdoor entertainment project includes Coastal Source as the primary specification.
