The VTX S28 is the companion subwoofer to the VTX V20 and V25/V25-II line array systems. Featuring two 2269H 18” drivers, these speakers provide substantial very low frequency performance through their neodymium-magnet transducers. The frequency range for these subwoofers is 24 Hz to 400 Hz, operating at a 2x 2000W continuous and 2x 8000W peak input power rating.
The VTX S28 can be either suspended independently, suspended in conjunction with VTX V25 speakers, or stacked on the ground. In each of these configurations, the S28s can be arrayed in either a front-facing or cardioid formation.
The appropriate array frame for this model is the VTX-V25-AF, and the extension bar for attachments for this array frame is VTX-V25-AF-EB.
From the Manufacturer
VTX series dual 18″ subwoofers employ two 2269H 18″ transducers featuring Differential Drive technology with two voice coils, two neodymium magnets and extremely high peak-to peak excursion capabilities to deliver extended very low frequency performance.
The VTX S28 can be suspended or ground-stacked and is cardioid-arrayable in either configuration for improved rear rejection. Compatible with VTX V25 suspension, S28 can be suspended at the top of V25 arrays to extend the effective low frequency line length, providing improved vertical pattern control combined with improved rear rejection when used in cardioid mode.
Alternatively, S28 arrays (cardioid or front-firing) can be suspended beside or behind V25 arrays. For theatrical sound design, S28 can be suspended in the middle of flown V25 arrays to facilitate balcony and floor coverage by allowing improved under-balcony penetration. Larger cardioid configurations are also effective where S28 is suspended or ground-stacked in multiple cardioid blocks, each block consisting of 3 enclosures (2 front-firing, 1 rear-firing).
