The SW28 is a direct radiating subwoofer to be operated on system amplifiers. The compact bass reflex system is equipped with two 18″ cone chassis and, owing to its linear tuning, produces a controlled low-end that goes down below 40 Hz. Symmetrically arranged port holes ensure an optimal coupling between several systems in a multiple configuration.
Electrically the SW28 is ready for cardioid operation mode.
A total of four Speakon sockets – two on the rear and two on the front – enable a front/rear system cabling without specially configured reversible cables.
The practice-oriented setups for the omnidirectional and cardioid operating modes ensure a safe operation and a linear transmission behaviour. In cardioid mode the SW28 subwoofers achieve a controlled radiation pattern with excellent rear damping.
Regarding its acoustical, mechanical and visual properties, the SW28 is compatible with the SW18 subwoofer. Both can be combined among each other and driven in omnidirectional or cardioid mode as required. Combined with our tops high-performance fullrange systems can be realised in various configuration levels.
„We have tested SW28 and HT16 with a live band and compared them to our present equipment. You’ve got to hear it for yourself. One can hardly describe it. A great system which thrills us time and again.“
