SoundTube RS1201i-SuperT™ Hanging Subwoofer in Black

The RS1201i is a 12-inch open-ceiling or surface-mount subwoofer tuned for maximum output and performance across the operating bandwidth. By incorporating a 12-inch treated fiber cone woofer and a treated cloth surround in a tuned and ported enclosure, this speaker delivers maximum low frequency response (32 Hz – 200 Hz, ± 10 dB, independently verified) and high SPL (113 dB). 


The SuperT™ is a special transformer that handles low subwoofer frequencies with very low losses. Mounting hardware includes high-quality UL listed cables and integrated SpeedClamp™ self-locking wire clamp for fast, easy and secure installation. For easy ordering, stocking and installation, the RS1201i includes a two-position tap switch for 70.7-, 100 volt and 4 ohm applications.
