The SW218XA generates an additional 3 dB of peak output, making it ideal for top-level concert touring and festival applications requiring higher levels of low-frequency response such as hard rock and electronic music. It does this by utilizing the unique 4” Tetracoil, two separate voice coils
wound on both sides of the same former and suspended in two axially separated magnetic gaps, enabling extreme excursion of the cone and suspension system. The SW218XA offers twice the output of the SW218A in the same size enclosure, so making it ideal for rental companies looking to increase total system SPL capability for the same amount of inventory

The SW218XA is also recommended for high-level dance music clubs and touring systems requiring very strong sub-bass energy with its 4000-watt class D amplifier module generating peak output of up to 143 dB and extended low-frequency response. The CORE DSP processing
allows for remote control of critical operating parameters, as well as comprehensive system monitoring.

The SW218XA features reinforced birch plywood cabinets with stacking feet and heavy-duty wheels.
