ACTION-525 is a passive system that incorporates two 15” speakers that deliver a greater SPL than the simple 15” plus enhanced bass for events that require both powerful sound and simple adjustment. 
 
 
As part of our company culture, all our systems are developed under a single philosophy: to deliver the highest possible quality in terms of both materials and overall system design. In the ACTION-500 series we use the same birch plywood as our touring systems for a tight, natural warm sound found nowhere else on the market. 
 
 
For long-term optimal performance of the ACTION-500 passive versions, the system can only be a complete sound system when rounded out with our amplifiers and processors with stored presets and limiters.
