In-Wall Speaker
IW500i
Technical Information for System Engineers
Key Features
• BroadBeam® waveguide technology
delivers 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.
• 107 dB Max. SPL offers high output capa-
bilities and reduced amplification costs.
Specifications: IW500i
• Rapid installation blind-mount system for
quick and secure installation.
