SoundTube IW500B‑WH 5.25-Inch In‑Wall Coaxial Speaker, White

The IW500B‑WH is a transformer‑tappable, in‑wall coaxial speaker featuring a 5.25″ polypropylene woofer and 1″ convex titanium tweeter with FerroFluid cooling. It is designed for distributed (25/70.7/100 V) or 8 Ω applications, utilizing SoundTube’s BroadBeam® waveguide for wide and consistent dispersion.

Featuring a sealed infinite‑baffle design with an integrated UL‑listed steel backcan, the speaker offers transformative flexibility via its six‑position rotary tap switch, including direct bypass. The low‑profile grille and constant‑tension mounting system enable fast installation and aesthetic integration.
