SoundTube - SM890i - 8" Surface Mount Speaker (Single)

SoundTube - SM890i - 8" Surface Mount Speaker (Single)

The SM890i is a premium high-SPL, high-efficiency surface-mount loudspeaker for distributed 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 consistent 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 internal wedge cam, which allows for stable and precise aiming from 0 to 90 degrees.

Corrosion-resistant materials, including powder-coated steel grille plus aluminum mounting hardware, make the SM890i ideal for indoor/outdoor use.


  • Patented BroadBeamHP® waveguide technology delivers a consistent dispersion pattern for maximum intelligibility and edge-to-edge coverage (up to 8 kHz, independently verified).

  • Easy-access six-position tap switch for 25/70.7/100-volt applications with transformer bypass position.
  • Powder-coated steel grille with tool-free locking system.
  • Tool-free, low-profile Stealth™ bracket with an integrated internal wedge cam for stable and precise aiming from 0 to 90 degrees. Mounting hardware is constructed of die-cast aluminum.
