Episode® Signature Preconstruction In-Wall / Ceiling Subwoofer Enclosure - Single 8"




The Episode Signature Preconstruction In-Wall/In-Ceiling Subwoofer Enclosure increases sound performance by adding consistent air volume. The preconstruction enclosure is capable of housing a single subwoofer in the ceiling. This enclosure has a minimal footprint, so you can easily hide subwoofers anywhere – small or large rooms, theatres, distributed audio, and more.



Increased Performance

A preconstruction back box will give a subwoofer a defined air volume for an improved and more consistent audio performance. A vinyl-wrapped MDF enclosure reduces both resonance of the subwoofer and noise transmission to adjacent rooms, and the included foam pads eliminate resonance even further. Plus, adding a subwoofer is known to improve a customer’s overall satisfaction with their sound system.




This enclosure is pre-wired for use with an Episode Signature Free Air Subwoofer.



Easy Wiring

A terminal cup on the outside of the enclosure allows for easy wiring before sheetrock is installed, while internal wiring within the enclosure allows for easy wiring of the subwoofer after sheetrock is added.



This enclosure is compatible with all existing 8" Episode grilles, which are available in round, square, bezel, bezel-less, and black options.



Wall Accommodation

This enclosure fits in a standard 2 x 6" hidden stud bay and can accommodate sheetrock thicknesses from single 1/2" to dual 5/4" for a flush install that won’t take up valuable space. The enclosure can span up to 24" between joists with included expansion arms, and arms also allow for side-to-side adjustment.



Easy Install

Simply mount the front-facing steel flanges to the stud, overlay the sheetrock, and cut using the included drywall flange for guaranteed hole cutout. Once this is completed, you can easily insert the subwoofer.
