Triad IWSURR4 In-Wall Surround Speaker
Special order - Please contact us
The Triad IWSURR4 is a high-performance in-wall surround speaker meticulously crafted for immersive audio experiences in both residential and commercial home theater environments. The IWSURR4 has been designed using advanced acoustic modeling and engineering to deliver enveloping surround sound, consistent dispersion and discreet architectural integration.
Featuring a 4-inch fiber dampened aluminum woofer, two midrange drivers and a 1-inch aluminum tweeter in a bipole/monopole configuration, the IWSURR4 ensures balanced off-axis performance and precise imaging. This configuration enhances the diffuse soundfield critical for surround channels, contributing to a seamless, cinematic listening experience from every seat in the room.
The IWSURR4 is engineered to deliver wide and immersive sound dispersion, making it ideal for Dolby Atmos, DTS:X, and other multichannel formats. Its sealed, acoustic back-box enclosure optimises performance while preventing sound bleed into adjacent rooms, maintaining clarity and punch in even the most demanding installations.
Perfect for dedicated theaters, media rooms and luxury entertainment spaces, the IWSURR4 pairs audiophile-grade sound quality with installation-focused features like flush-mount design and custom color-matched grilles. This allows for a refined, nearly invisible finish that complements any décor while maintaining professional-grade performance.
Whether used in a premium surround setup or as part of a larger immersive audio system, the Triad IWSURR4 delivers exceptional surround sound performance with a clean, architectural aesthetic.
