Frequently asked questions

No. The ACK1 is explicitly designed for mobile applications—it adds mobility to stationary subs. The MTC-200BB6 is engineered for permanent in-ceiling mounting and is not suited for portable live sound.

What subwoofers or speakers do these pair with?

The ACK1 is compatible with JBL SRX900 Series subwoofers. The MTC-200BB6 is designed specifically for JBL Control 227C and 227CT loudspeakers in ceiling installations.

What is the skill level required to install each?

The ACK1 is suitable for beginners through professionals—it's straightforward hardware attachment to enable mobility. The MTC-200BB6 is marked for professional installation due to the structural and acoustic considerations of in-ceiling mounting in commercial spaces.

How do these differ in construction philosophy?

The ACK1 prioritizes smooth movement and vibration isolation during transport with steel and polyurethane. The MTC-200BB6 prioritizes acoustic damping and cabinet rigidity for fixed installations, using 16-gauge metal and MDF to prevent resonance and optimize speech clarity.
