Good for a Clean Installation

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

Crutchfield Customer Review (What's this?)

I coupled this speaker plate with what may have been the last MB2 in Crutchfield stock and finally cleaned up the output for a sloppy in-wall speaker job. The unit itself is a heavy duty piece of equipment and accepted a binding post connection on one side, and a banana plug connection on the other with ease. I have 5 speaker pairs connected with 14 and 16 gauge wire and there was never an issue with getting the wires into the correct position. It was my own fault for not calling Crutchfield to discuss my purchase but it was a last minute discovery that I needed the Niles MB2 wall mounting plate to make it all work right. Installation would have otherwise been a huge mess.

Pros: Heavy duty, clean connectivity, great fit and finish with the (discretely) suggested wall plate.

Cons: Needs the extra equipment, unless you just happen to already have an MB2 wall plate handy.

Quality Product

Crutchfield Customer Review (What's this?)

Really liked this product and the fact that the backing plate was metal and not a
flimsy plastic product.
I did note the required mounting plate and ordered it at the same time so no
heartache there.

Perfect piece, but you MUST order mounting bracket

Written By Randy, Reno, NV on Wednesday, May 27, 2009

Crutchfield Customer Review (What's this?)

Piece is perfect, heavy duty and well constructed. My only grip is that the mounting bracket is required in order for the piece to be installed and no mention of that was made when ordering. Had to pay for additional expedited shipping on a separate occasion in order to install. Good customer service though.
