ACTION-S18 is a passive direct radiation subwoofer system composed of a single 18FW speaker with a 3” coil and 20 mm winding depth, double layer and sandwich to boost system power, as well as a new forced convection circuit that works to reduce the effects of coil heating, improving the system’s overall performance as a result.
For long-term optimal performance of the ACTION-500 passive versions, the system can only be a complete sound system when rounded out with DAS Audio's amplifiers and processors with stored presets and limiters.
