The Cloud CS-SUB8W & CS-SUB8B passive subwoofer is designed to be shelf or surface mounted.

The 8" treated paper woofer is mounted in a compact MDF / plywood cabinet for a rich and powerful bass sound to compliment the other Cloud CS range of speakers.

Finished in black or white and rated at 100 watts, 100 volt line and 4 ohm. A tapping selector on the rear provides transformer tappings at 100, 50, 25, 13 and 7 watts as well as a bypass for 4 ohm connection.

This versatile speaker is fitted with rubber feet for a stable footing on a surface, or it can be wall mounted either horizontally or vertically using the included wall mount bracket. The CS-SUB8 can also be flown using the threaded eyebolt sockets.

Using a premium woofer and first order crossover network, the CS-SUB8 adds punch and low end reinforcement to Cloud’s line of full range speakers.

The 8.0 inch woofer incorporates a large magnet structure, treated paper cone, and long throw butyl rubber surround for lasting, low distortion performance.

The included 100 W transformer provides plenty of power for background and foreground music applications.
