The SM890i is a premium high-SPL, high- efficiency surface-mount loudspeaker for distrib- uted or 8 ohm systems. The SM890i incorporates a dedicated 8-inch treated fiber woofer and a high-power compression horn transducer with a BroadBeamHP® waveguide to deliver a consis- tent dispersion pattern and superb intelligibility for the foreground music, sound reinforcement and PA markets. The SM890i uses a 150-watt low-insertion loss transformer and a six-position tap switch with a transformer bypass position. Mounting hardware includes SoundTube’s proprietary tool-free, low profile Stealth™ bracket with an integrated inter- nal wedge cam, which allows for stable and precise aiming from 0 to 90 degrees. Corrosion-resistant materials, including powder- coated steel grille plus all-aluminum mounting hardware, make the SM890i ideal for indoor/outdoor use
