Product Description
Each GSF3-TN pairs a 3" polypropylene woofer with a 0.8" titanium dome tweeter, covering 74 Hz to 20 kHz across a 90-degree conical pattern. The enclosure is IP66 rated against water and dust, a bottom drip hole drains the speaker, and the tap selector sits on the underside away from rain. A ground stake and L-bracket come with every speaker, so you can stake them into planting beds or mount them to walls, fences, and eaves, then aim each one with the adjustable hinge.
The GSB8-TN installs underground with only the audio port showing. Its 8" driver reaches down to 35 Hz, and a built-in steep lowpass filter keeps it focused on bass while the GSF3 speakers cover the rest. The chamber sits directly below the port to avoid damage from landscaping, and grab handles plus anchor tabs make burying and securing it straightforward.
On the amp side, the RCS350-6 delivers 350W at 70V. Tap all ten speakers at their full 15W and the sub at 100W, and the system totals 250W, comfortably under the recommended 300W load. Six zones with individual volume knobs let you set the patio, pool, and walkway separately, and Bluetooth, USB, SD, optical, and line inputs cover music. Three mic inputs with echo control and a chime button handle announcements.
Features
A Complete Outdoor System
Ten GSF3-TN speakers, a GSB8-TN subwoofer, and the RCS350-6 amp come together, so patios and gardens get full-range sound without piecing parts together.
Real Bass Outdoors
The GSB8-TN 8" in-ground subwoofer reaches down to 35 Hz, with a built-in lowpass filter that keeps it on bass while the speakers handle detail.
Built for the Elements
IP66-rated GSF3-TN speakers resist water and dust, and the buried GSB8-TN shows only its audio port, keeping hardware protected and out of sight.
Placement That Fits the Yard
Every speaker includes a ground stake and L-bracket, with an adjustable hinge to aim sound at seating areas, walkways, and pool decks.
Power With Room to Spare
The RCS350-6 delivers 350W at 70V across six zones, and all eleven JBL units at full tap total 250W, well within the recommended load.
