More details on the Definitive Technology DI 8R Rough-in Brackets

Product Research


Overview: When planning speaker installations in new construction many installers find it useful to install rough-in brackets onto wall studs or ceiling joists so that the sheetrock contractor knows precisely where to cut the appropriate size holes. The DI Series rough-in brackets were custom designed from the ground up to be easy to install. The "arms" are metal mesh and can easily be attached to wood or metal studs using nails, dry-wall screws, or construction staples. The arms easily detach and can be positioned at various points around the bracket to accommodate unusual stud/joist locations. The center ring is heavy gauge steel that will not bend or break with rough handling and sloppy drywall cutting by subcontractors. The convenient wire tie loop is scored to allow easy snap off once the speaker is installed.

Compatibility: The DI 8R rough in bracket is compatible with Definitive Technology's 8.0" Disappearing In-Wall Loudspeaker (DI 8R).

Note: DI Rough-in Brackets are packaged two to a carton (2 mounting rings and 4 mounting arms). Mounting screws not supplied.

Metal Rings: The center rings are fabricated from heavy duty painted stamped steel. There are no sharp metal edges to cut an installer's hands and they are ultra rigid, so that when drywall is laid over and cut the brackets will not bend or break. The center ring requires a 8.8125" diameter cutout.

Mounting Arms:  The metal mesh mounting arms snap onto the center ring in a variety of positions to cover almost any installation. The wings can be attached with nails, staples or screws; and can be bent and easily trimmed with tin snips. They are also thin enough to make stud notching simple. The wire tie loop easily breaks away when the speaker is installed.


  • Metal Ring: Diameter = 10.875", Depth = 0.8125"
  • Mounting Arms: Width = 12.4375", Height = 1.9375", Depth = 0.5625"
  • Overall Dimension: Width = 35.25", Height = 10.875", Depth = 0.8125"
  • Cutout: Diameter = 8.8125", Depth = 0.4375"

Customer Q&A

Crutchfield asked: Why did you buy this?
I have a new build so no drywall yet. 1. This allows me to precisely plan the speaker locations before drywall 2. Based on the dynamic range of these speakers, I will prefer more robust joist support other than just drywall. [ Raphael  May 07, 2017 ]
Using them to place in home during new construction for future speakers. [ Thomas  Mar 04, 2016 ]
