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 enclosure
volume 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
multiple cardioid blocks, each block consisting of 3 enclosures (2 front-firing, 1 rear-firing).
