Bollard Speaker with Inground Subwoofer

Abstract

Improvements in a bollard speaker with in-ground subwoofer where the bollard contains a first speaker for higher frequencies and the subwoofer that provides lower frequencies that emit from below ground up through the bollard through a grill in the middle or upper portion of the bollard. The in-ground subwoofer provides a structural foundation for the bollard. Placing the subwoofer in an underground housing allows for larger speaker sizes for improved lower frequency response without trying to produce low frequency sounds in a constrained vertical bollard housing pole. The same base subwoofer is used with interchangeable bollards that accommodate both a cylindrical and a square or rectangular above ground bollard. The speaker within the bollard is configurable for omni-directional or directional sound transmission.
