Frequently Asked Questions

It’s a physical locking mechanism; the satellites securely attach to the subwoofer, creating a cohesive mono signal without complex wiring.
You'll realistically see around 110-115 dB SPL at 1 meter, depending on the material and room acoustics - plenty for smaller to medium-sized spaces.
While usable for vocals, the satellites are geared more towards music reinforcement; a dedicated vocal monitor or more advanced PA system would be preferable for critical vocal clarity.
