The CM1001d-T is a 10, blind-mount, in-ceiling subwoofer tuned for maximum output and performance across the operating bandwidth. By incorporating a 10 polypropylene woofer and a butyl rubber surround in a tuned and ported enclosure, this speaker delivers maximum low-frequency response (41 Hz - 224 Hz, - 10 dB) and high SPL (111 dB). For added low-end punch, SoundTube has incorporated an oversized enclosure and tuned, flared port. Mounting hardware is included and features a constant-tension fixed-wing mounting system with a 21-gauge full-metal steel tile bridge, ensuring rapid and secure installation in any sheetrock or drop-tile application. Restraint cable included for easier installation. Applications The CM1001d-T is a background to foreground subwoofer for installations where high quality, true bass response and rapid installation are critical variables. Aerobic rooms, retail, restaurants, nightclubs, hotels, bars, theme parks, arenas, ballrooms and churches are all ideal fits for the CM1001d-T. Because overall system design is a critical component of subwoofer integration, SoundTube recommends incorporating a DSP system with an active crossover to maximize the subwoofer integration and overall system performance. Tuning the system based on room acoustics and loudspeaker selection will result in smooth response and reduced subwoofer localization.
