Active 2x18'' Subwoofer

Since the 90’s the Line-Array technology has changed soundreinforcement drastically. The vertical arrangement of speakers in an enclosure offers a high influence to soundspreading and reduces in comparison to ordinary soundsystems the loss of signal in relation to distance combined with a slim structure and broad sound distribution.

DVA makes this technology, which up to recently was only provided in high profile projects and installations, available for a broad range of budget orientated applications. All relevant criteria like weight, acoustic handling including purchase price and additional costs in form of transport and flying accessories have been well considered. Despite above mentioned features, the DVA is not limited in terms of curving and maximum amount of possible Array-Elements, like products of competitors in recent history in this segment. Specially the individual curving, optimised to the demands of the event, enables the acoustic advantages and shows the flexibility of DVA.

dBTechnologies designed a Line Array which sets new standards in handling, flexibility and profitability by using most modern technology and materials, with a vast amount of knowledge and experience in building active loudspeaker systems. The DVA T4 Line-Array element has a sensational weight of only 13,2kg. The obvious advantage for handling and transport also makes flying possible where under normal circumstances the trussing is not strong enough to support also flying of the audio devices - an Array of six T4 Tops therefore weighs less than 120 kg.

Featuring a dual 18” subwoofer pairing in a bass reflex housing, the DVA S20 delivers powerful performance, rendering frequencies as low as 25 hertz assertively and with impressive authority. It is the perfect sub-bass provider for DVA S10/T4 systems and an excellent complement to DVA T4 mid-/high-range units in stacked arrays.

RCF Precision Woofer.
The DVA S10 and S20 subwoofer are equipped with powerful RCF Precision woofers with neodymium magnets and a 4” voice coil for extremely high sound pressures. Double ventilation provides an optimum of cooling, a minimum of power compression at high reliability. The woofers are fibreglass reinforced and have a triple-roll coil embedded in a perfect edging with constant geometry. This combination makes an extreme peak-to-peak steering of up to 48mm possible.
