Description
Featuring a dual 18" subwoofer pairing in a bassreflex-horn housing, the DVA S30 N packs a muscular, ultra low-frequency 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 fiberglass-reinforced 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.
