Description

The SM500i is a 5.25” 2-way surface-

mount speaker with a midsize enclosure

design that delivers effective low-end

response (45 Hz) and optimal off-axis

performance (up to 10 kHz, EASE

™

documented). SoundTube’s proprietary

BroadBeam

waveguide tweeter

system delivers consistent high-perfor-

mance audio across operating bandwidth.
The SM500i speaker design incorp-

orates a low-profile grille, proprietary

™

motor-board, 6-position tap switch

with voice coil/8 Ohm direct and mount-

ing hardware, including a fast Speed-

Lever

™

mounting system.

Applications

Designed for indoor & outdoor back-

ground to mid-level SPL surface-mount

applications, the SM500i includes a
