(6) Pair JBL-GSF3-GN + JBL-GSB8-GN + RCS350-6

Six pairs of GSF3 landscape speakers, a GSB8 in-ground subwoofer, and the RCS350-6 six-zone amplifier give hotel grounds, restaurant patios, resort pool decks, retail courtyards, and theme park paths a full-range 70V outdoor system for background music and paging. Each GSF3 uses a custom two-way coaxial driver, pairing a 3" polypropylene woofer with a 0.8" titanium dome tweeter, for clear sound from 74Hz to 20kHz across a 90° conical pattern. The GSB8 fills in the low end the small satellites can't reach, with an 8" driver that extends down to 35Hz and a steep multiple-slope lowpass filter that keeps it focused on bass.

Both speakers are built to stay outside year-round. The GSF3 is IP66 rated against water and dust, drains through a bottom drip hole, and keeps its tap selector on the underside, away from rain. Each one ships with a ground stake for planting beds and an L-bracket for walls or posts, and an adjustable hinge aims it at seating areas. The GSB8 installs underground with only its audio port showing, and its chamber sits directly below the port so landscaping work won't damage it.

The RCS350-6 is the amplifier this system needs anyway, so there's no separate purchase to plan. Tapping all twelve GSF3s at 15W and the GSB8 at 100W totals 280W, inside the 300W speaker load recommended for this amp. Six zones each get their own volume knob, so the patio, entrance, and pool deck can play at different levels. It streams over Bluetooth, plays USB, SD, FM, optical, and line sources, and takes three mic inputs with echo control plus a chime for announcements, all in a rack mountable unit with detachable euro-block terminals.
