JBL Professional VTX-S28 - Dual 18" High SPL Cardioid Suspension Subwoofer

The VTX Series of dual 18" subwoofers employ two 18" 2269H transducers, featuring Differential Drive technology with dual voice coils, dual neodymium magnets, and extremely high peak-to-peak excursion capabilities to deliver extended very low frequency performance. The VTX S28 can be flown or ground stacked and is capable of forming cardioid arrays in any configuration for improved rear rejection. Compatible with the VTX V25 suspension, the S28 can be flown on 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. For theatrical sound design, the S28 can be flown in the middle of flown V25 arrays to facilitate balcony and floor coverage by allowing better under-balcony penetration. Larger cardioid configurations are also effective when the S28 is suspended or ground-stacked in multiple cardioid blocks, each block consisting of 3 enclosures (2 front and 1 rear).
