The VS28 is a direct-radiating groundstack subwoofer to be operated on system amplifiers. The bass reflex system is equipped with two 18“ cone drivers and, due to its linear tuning, produces a controlled low-end down to below 30 Hz. With multiple stackings the symmetrically arranged port holes ensure an optimum coupling of the systems among each other.
Electrically the VS28 is ready for the cardioid operating mode.
A total of four Speakon sockets – two on the back and two on the front – allow a front/rear system wiring without the need for custom-made reversible cables.
The practice-oriented setups for the omnidirectional and cardioid drive guarantee a safe operation and a linear transmission behaviour. In cardioid mode the VS28 subwoofers achieve a controlled directivity pattern with an excellent rear attenuation.
In acoustical, mechanical and visual terms the VS28 is compatible with the VS18 subwoofer. Both may be combined in omnidirectional or cardioid mode as you choose.
