Features

Overview: The Coastal Source 10.0 Ellipse Bollard Subwoofer is designed for in-ground and above-ground installations and features a sleek design that can be easily hidden within a landscape, yet looks great when installed out in the open.

Construction: The 10.0 Ellipse Bollard features a 7"x10" subwoofer driver that offers higher performance and efficiency than conventional outdoor speakers. The subwoofer driver is housed in a durable roto-molded composite enclosure designed for outdoor use. The Ellipse Bollard subwoofer can provide 360˚ of sound dispersion that can cover 100-400 sq. ft. of listening area.

Power & Connections: The 10.0 Ellipse Bollard subwoofer features a pair of male CC (Coastal Connector) input connectors for connection to an amplifier. The Ellipse Bollard subwoofer can handle between 50W (minimum) and 100W (maximum). Coastal Connection cables (sold separately) feature threaded connector-ends designed to provide a watertight connection that's rated for direct-burial.

Installation: The 10.0 Ellipse Bollard subwoofer can be either landscape or hardscape installed. For landscape installations, the speaker can be installed in-ground with the woofer grille exposed. The subwoofer can also be installed in-ground at a 45˚ angle, with the grille perpendicular to the ground. This installation method produces the heaviest bass response by allowing low-frequencies to travel through and be reflected by the ground. Optional Landscape Stakes and a Theft Guard (both sold separately) can be used to mount the speaker above-ground while maintaining a stable installation. The 10.0 Ellipse Bollard subwoofer can also be hardscape mounted to flat surfaces. Optional Isolation Spikes (sold separately) allow the speaker to safely sit on a hard surface, while a Hardscape Mount bracket (sold separately) allows the speaker to sit inside a recessed mounting area of a flat surface.
