Yamaha ASP1 Adjustable Subwoofer Pole

Adjustable length speaker support made specifically for mounting a full-range loudspeaker above a subwoofer. Height adjustment range from 26" to 37". A safety pull pin is also included for extra security. The weight of the speaker drives a spring-loaded mandrel against 3 pressure pads, essentially filling the gap between the pole and the speaker mount. The result is a straight, steady speaker system with a professional look. The extension can be removed for use with shallow subwoofer mounts from other manufacturers.
