Furrion Aurora® 2022323828 4.1 Landscape Speaker System Terrace Series - High-performance audio for enhanced outdoor entertainment just got better. Mount your landscape speakers anywhere with the included ground stakes or the universal mounting bracket (sold separately) that can be attached to a deck surface, post in your landscaping or trees in your yard. With the pivoting arm assembly and 1/2" NPT brass fitting, you can enjoy 150 degrees of vertical rotation, allowing you to adjust your outdoor speakers to just the right angle. The subwoofer features a multi-mount design, meaning you can mount it above-ground, in-ground or on your deck. In addition, this landscape speaker system is expandable, so you can add up to four satellite speakers and one subwoofer, depending on the size of the amplifier. This will allow coverage of up to 3,500 sq. ft., depending on the landscape layout. The additional speakers and subwoofer must be Furrion-branded.
