Featuring a dual 18” subwoofer pairing in a bassreflex-horn housing, the DVA S30 N packs a muscular, ultra lowfrequency punch. It delivers very powerful performance indeed with a range extending down to the lowest frequencies.

This sub-bass powerhouse is the perfect addition to large PAs and an excellent complement to DVA series mid-/high-range units in stacked arrays.

This sophisticated hybrid design brings together the benefits of bassreflex and horn systems in a compact housing engineered to render low frequencies with high SPL.

The two baffle boards are arrayed in the form of a V. They guide the central bass reflex channel sound energy into the horn port. This funneling action is smooth and uniform, greatly increasing its range.

The high-quality multiplex housing is covered in robust black textured lacquer and equipped with eight grips. On the back is a transport dolly that removes easily via quick-release pins to keep the wheels from rattling.

The woofers feature a 4” voice coil, a fiberglassreinforced diaphragm, an exceedingly robust triple-roll surround, and a geometrically optimized cone. All this culminates in very high peak-to-peak excursion capabilities.

The DVA S30 N is driven by two digipro®G2 digital power amps with up to 3000W output. Digipro®G2 technology is so very efficient that it does not require fans. With no moving parts to tend to, these amps are altogether maintenance-free. It is also equipped with PFC switched-mode power supplies, immune from line voltage fluctuations.

They feature a premium-quality DSP boasting excellent audio specs with variable crossover frequencies, precise limiter functions and adjustable delay settings for perfect time alignment. A special preset makes it easy to set up cardioid systems with enhanced directivity. The DSP also provides an X-Over output for connecting satellites.

Factory-equipped with an RDnet port, DVA S30 N is ready for integration into elaborate, remotely controlled and monitored DVA systems via RJ45 inputs and outputs that connect the units to the RDnet hub.

Optional dust covers protect it on the go. With 16 threaded bushings on its rear panels, the S30 N is ready to accept Blue Wheels.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
