General Description
Optional square grilles (black and white available)
The Cloud CS-CSUB8 is an 8 inch in-ceiling subwoofer featuring
deep bass and exceptional musical performance. Using premium
drivers and electronics, the CS-CSUB8 offers excellent low frequency
reinforcement. The 8.0 inch woofer incorporates a large magnet
structure, a treated paper cone, and a butyl rubber surround for
lasting, low distortion performance. The included 100 W transformer
provides plenty of power for even high SPL applications.
The CS-CSUB8 incorporates several innovative features that
make it a truly remarkable speaker. The ZeroEdge™ grilles are
magnetically attached for easy installation, and feature a completely
seamless transition from grille to ceiling. Round grilles are supplied
as standard: square grilles may be ordered as an option if preferred.
Both grille styles are available in black or white nish. The entire
CS-C series of speakers uses the same diameter back can which
simpli es installation, and inventory management with only one size
hole to cut, one size grille to install, and one size tile bridge to bring
to the job site.
The CS-C8SUB may alternatively be converted to a pendant
loudspeaker by installing it in the optional PC-200 Pendant Housing
(available as an accessory).
