What types of venues and events typically require the VTX S28 dual 18-inch subwoofer?

The VTX S28 is engineered for large-venue installations, major festivals, and touring shows needing deep, powerful bass output. Its 139 dB SPL rating makes it ideal for outdoor festivals and arena-sized venues.

How does Differential Drive technology in the VTX S28 improve low-frequency performance?

Differential Drive technology optimizes transducer motion and output efficiency, maximizing bass impact and extension compared to conventional designs. This enables deeper low-frequency coverage without increasing cabinet size.

Can the VTX S28 be deployed suspended from rigging points or must it be ground-stacked?

The VTX S28 is designed for both suspended rigging and ground-stacked configurations, giving system designers flexibility for different venue layouts.

What is the lowest frequency the VTX S28 can reproduce, and what does that mean for music coverage?

The VTX S28 extends frequency response down to 29 Hz, capturing the sub-bass content essential for modern electronic music, hip-hop, and live drum performances.

How many VTX S28 subwoofers would typically be required for a major outdoor music festival?

The number depends on audience size, venue dimensions, and desired low-frequency coverage; festivals typically deploy multiple units across the audience area. Contact Procure.ae with your specifications for a system design recommendation.
