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. Two VTX Subwoofer models are available: VTX-G28 and VTX-S28, both models are reverse cardioid-arrayable.
The VTX-G28 is ground stackable only with a practical form factor for convenient stacking and additional enclosurevolume plus port tuning that delivers true sub performance down to 22 Hz @ -10 dB.
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 VTX-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, VTX-S28 arrays (cardioid or front-firing) can be suspended beside or behind V25 arrays. For theatrical sound design, VTX-S28 can be suspended in the middle of flown VTX-V25 arrays to facilitate balcony and floor coverage by allowing improved underbalcony penetration. Larger cardioid configurations are also effective where VTX-S28 is suspended or ground-stacked in multiplecardioid blocks, each block consisting of 3 enclosures (2 front-firing, 1 rear-firing).
