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).

Documentazione

VTX V25 AF EB | Telaio Array

Immagini più grandi

Accessorio barra di estensione utilizzato in combinazione con il telaio array VTX-V25-AF per distribuire i sistemi della serie VTX V25 in modalità di compressione o trazione. Cinque opzioni di attacco della barra di estensione forniscono separazione variabile dei punti di prelievo (sospensione a 2 punti) e maggiore flessibilità per la sospensione a punto singolo. La barra di estensione può essere montata anteriormente o posteriormente per aumentare l'inclinazione verso l'alto o verso il basso dell'array, rispettivamente. Se montata posteriormente, fornisce un punto di attacco per la sospensione in compressione. Una singola barra di estensione può essere installata nel tubo centrale del telaio dell'array, oppure, in alternativa, una coppia di barre di estensione può essere montata anteriormente o posteriormente nei tubi dei telai dell'array sinistro/destro. Le barre di estensione singole o doppie possono anche essere montate anteriormente o posteriormente nelle applicazioni in pila da terra per una stabilità extra e una gamma più ampia di opzioni di inclinazione dell'array. Le barre di estensione doppie possono anche essere montate anteriormente e posteriormente per la sospensione in compressione quando è richiesta una maggiore inclinazione verso l'alto dell'array.

Caratteristiche:

Compatibile con VTX-V25-AF
2 x punti di prelievo disponibili per sospensione a punto singolo
1 x punto di prelievo disponibile per l'attacco al verricello livellato VTX-V25-LH
Supporta fino a 24 cabinet (dipende dalla geometria dell'array)
Dimensione maniglia del punto di prelievo: 5/8" o 3/4"

Incluso:

1 x barra di estensione VTX-V25-AF-EB
