Frequently asked questions
Are these products compatible with each other?
No. The MTC-81BB8 is a backcan for ceiling speaker installations, and the MTC-SG6/8 is a grille for existing Control series speakers. They serve different purposes and are not used together.
Which one is for live performance?
The MTC-81BB8 description lists live performance as a best-use case because it supports ceiling speaker systems in venues. The MTC-SG6/8 is explicitly not ideal for live performance touring, as it is designed for permanent commercial installations.
Do these come with all necessary mounting hardware?
The MTC-81BB8 uses M4 clip-nuts and requires four attachment points; five conduit knockouts are provided for cable entry but additional hardware may be needed depending on your ceiling structure. The MTC-SG6/8 includes five M4 machine screws, covering the four required for mounting plus one spare.
What finish options are available?
The MTC-81BB8 comes in black polymer E-coat for corrosion resistance in industrial settings. The MTC-SG6/8 is finished in powder-coated satin white (RAL9016), designed to blend into commercial interiors.
