DVS 118 SW is a loudspeaker system suited to high SPL reinforcement of low frequencies, fitted with a 46 cm (18″) long-throw woofer. Loading is of the phase inversion type with the enclosure tuned at a rather low frequency.The peculiarity of this overall 4th order loading consists in obtaining a wide band-pass and great extension towards the bottom end of the frequency response. The standard components used allow to obtain a useable bandwidth reproduced at -10 dB from 26 Hz to 500 Hz, with remarkable linearity within ±3 dB from 35 Hz to 350 Hz, enabling the system to be used in a wide range of applications for sound reproduction from low to mid/low frequencies. The max sensitivity is 101 dB in half space and the maximum continuous AES power 700 W gives 132 dB SPL while peak values even reach 142 dB SPL. The rectangular shaped system is built in sturdy phenolic glued 15 mm baltic birch plywood that is resistant to damp, even in outdoor applications. Inside, as well as the bracing, which stiffens the panels and avoids vibration, the long tuning port also doubles as bracing. The external finish is in high quality scratch-resistant black paint. The front is protected by an anti-resonant sound-transparent steel grille. There is a receptacle for mounting the optional support of a satellite (if used); integral handles facilitate handling and an optional trolley to facilitate the transport, even on uneven surfaces.
