Frequently asked questions
Can I use either of these with the same speaker models?
No. The MTC-TB6/8 is designed for JBL Control 227 and Control 328 ceiling speakers with specific backcan compatibility. The WB8 is engineered solely for JBL C128W/WT in-ceiling speakers. Each mounting solution is speaker-specific.
Which one works in a retrofit or existing building?
The MTC-TB6/8 is designed for existing suspended ceiling grids and mounts over the grid without requiring ceiling alterations. The WB8 requires access to wall or ceiling cavities before drywall is installed, making it suitable only for new construction or renovation projects with walls open.
What is the main acoustic benefit of each?
The MTC-TB6/8 actively isolates the speaker from the ceiling grid to eliminate vibration and rattle that degrades sound clarity in commercial spaces. The WB8 provides rigid positioning that prevents speaker shift during construction, ensuring proper acoustic placement once installation is complete, but does not provide vibration isolation.
