Key Features
• BroadBeam® waveguide technology deliv-
ers a consistent dispersion pattern up to
10 kHz for maximum coverage area per
speaker (EASE™ documented).
• One 133 mm (5.25 in) polypropylene
woofer and one 25 mm (1 in) convex alu-
minum tweeter with FerroFluid cooling
mounted to an M5 Motorboard.

bilities and reduced amplification costs.
• Rapid installation blind-mount system for
quick and secure installation.
• Easy-access 6-position tap switch for 25,
70.7 & 100 Volt applications with voice
coil/8 Ohm direct simplifies ordering &
inventory tracking.
• Integrated UL-listed steel enclosure with
conduit connections.
• Included accessories: Mounting hardware,
paint mask, hole template and conduit
connector.
• Optional accessory: Pre-construction
bracket (AC-IW5-PCB).
• High-quality white paint finish. Custom
paint colors optional.
Description
The IW500b is a 5.25” coax in-wall loud-
speaker that delivers effective low-end
response (69 Hz, -10 dB) and optimal off-
axis performance (up to 10 kHz, EASE™
documented). SoundTube’s proprietary
BroadBeam® waveguide tweeter system
delivers consistent high-performance
audio across the operating bandwidth.
The IW500b speaker design incorporates
a low-profile grille and 6-position tap
switch with an 8 Ohm bypass. Mounting
hardware is included and features a fast
and secure optimally engineered constant-
tension mounting system and an inte-
grated backcan for maximum efficiency
and applications where UL approval is
required. A pre-construction bracket is
offered as an optional accessory.
Applications
Designed for in-wall applications, the
IW500b is ideal for music and messaging
in boardroom, church, corporate A/V and
education applications. For additional
bass response down to 41 Hz (-10 dB), the
CM1001d subwoofer may be used.
