The Innovox Audio SL-2.1RH is a horizontal-mount version of the SL-2.1R. This slim profile 2-way loudspeaker is designed to be surface-mounted and disappear into the architectural surroundings. Its precision ribbon HF driver and two 4” long-excursion LF drivers resolve complex audio program with detail and clarity that does not seem possible from such a small package. This version comes with a black finish, but white and custom colors are also available.

The addition of an available SBC-110 ceiling mounted sub-woofer extends low frequency response to 34 Hz and increases maximum system SPL.
