Dual 18" Subwoofer - Suspendable

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 underbalcony 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).

Extension Bar accessory used in conjunction with the VTX-V25-AF array frame for deploying VTX V25 series systems in either compression or tension mode. Five extension bar attachment options provide variable pick point separation (2-point suspension) and added flexibility for single point suspension. The extension bar can be front- or rear-mounted for increased array up-tilt or down-tilt, respectively. When rear-mounted, provides an attachment point for compression suspension. A single extension bar can be installed in the array frame central tube, or alternatively, a pair of extension bars can be front or rear-mounted in left/right array frame tubes. Single or dual extension bars can also be front- or rear-mounted in ground stack applications for extra stability and a wider range of array tilt angle options. Dual extension bars can also be front-and rear-mounted for compression suspension when increased array up-tilt is required.
