James Loudspeaker PowerPipe subwoofers were created as the world’s first and finest hidden subwoofer. PowerPipe utilizes a flexible tube to move bass energy from a hidden location into the listening space through a visually unassuming grille. These subwoofers use a durable, sealed aluminum enclosure that can be concealed just about anywhere, such as above ceilings, nestled in sub-floors or stowed away in a closet. The flexible tube is positioned from the subwoofer enclosure to the chosen port option. James Loudspeaker offers an expansive selection of standard or custom port options, providing a seamless decor treatment for even the most discerning clients and designers.
