Great for a Neat and Tidy in-wall install

Written By JasonR, Chicago, IL on Monday, January 14, 2013

Crutchfield Customer Review (What's this?)

Discovered I needed this piece of equipment to mount a Niles 5w-24 speaker plate. (I know - should have called Crutchfield to confirm installation instructions) Was lucky to get an open box item which arrived in "New" condition with all mounting hardware and equipment. Unit fit snugly into the prescribed size hole in drywall and held heavy speaker plate cleanly. Plate is rather large - slightly larger than an iPad so make sure the size is appropriate for your install.

Pros: Well constructed, easy to install, makes for a nice clean install.

Cons: The plastic backing plate is - well - plastic. It's not fragile, but it's not entirely rigid either.

Product Research


Overview: The Niles MB-2 accommodates the installation of two Niles 5W-24C speaker terminal panels. The kit includes a full-size frame, two inserts with pre-drilled holes for the mounting of two 1/2 speaker terminal frame panels, 8 machine mounting screws, and a blank 1/2 frame plate to cover an unused half of the frame when you are only using one 5W-24C speaker terminal panel.

Installation: The MB-2 can easily be retro-fitted using the four dog ears attached to the back of the frame which clamp the panel securely to the cut-out of the drywall. Optional Niles MB-6BK brackets are available for new construction installation. The 5W-24C speaker terminal panels mount from the back of the MB-2 frame using the supplied machine screws. The MB-2 requires a hole cut out of 8" wide x 10-1/2" tall.
