Triad InWall Slim 8 Inch Passive Subwoofer

Triad InWall Slim 8" Passive Subwoofer
Deliver deep, resonant bass while saving space with Triad® Slim Subwoofers. Designed to fit in a standard 2x4 studbay, these subwoofers deliver robust, controlled low frequencies to enhance any media experience while seamlessly fitting into tight spaces. Built with custom-designed in-house drivers and sealed, braced enclosures, these subs ensure a high output with minimal distortion for crisp, immersive audio. Each unit is handcrafted to deliver premium sound quality, and grilles can be custom color-matched to complement any decor. Triad Slim Subwoofers were designed in tandem with our Triad Subwoofer RackAmps to provide maximum power with every efficiency in mind.
High-Output Aluminum Cone Driver
Triad Slim Subwoofers' aluminum cone offers superior rigidity for reduced distortion and more accurate bass. Its lightweight design delivers a faster response, improved transient performance, and excellent heat dissipation to prevent overheating. Its durability makes it resistant to environmental factors like moisture and temperature changes, ensuring long-lasting, precise, and consistent performance.

Flexible and Uncomplicated Installation Method
Simplify installation with the innovative patent-pending spring dog system that provides flexibility to mount in various surfaces, bypassing studs or joists with ease while freeing up your hands to screw in and install the speaker without worry.
Resonance-Free Solid MDF Cabinet
Fully engineered, premium MDF enclosures with internal bracing components are rigid and precision-crafted to break up acoustic standing waves.
Built-to-Order, Made in the USA
Triad speakers are built to order on-site in our Portland, Oregon manufacturing facility by a team of passionate craftspeople and audio experts for custom, high-quality construction.
Choose the Size to Fit Your Install
With 4- or 8-ohm versions available in 8", 10", and 12" sizes, you can choose the optimal audio and bass performance to suit your customer’s space.
Removeable Magnetic Grille
The industrial design of the Triad subs, with their timeless look and modern influence, makes them worthy of showcasing with or without the bezel-less magnetic grilles installed.
Custom Grille Paint-Matching Service Included
All Triad InWall Slim subwoofers come with a custom color paint matching service, so you can match the Subwoofer's grille color to blend in with any décor.
