The two way switchable bi-amp / passive Stasys 4 consists of a very robust 15" low frequency driver and a 1.5" neodymium high frequency compression driver coupled to a rotatable conical 90° horizontal by 50° vertical waveguide. Our research showed that the Stasys 4's conical waveguide gave better off-axis rejection and constant coverage within its dispersion angle than conventional horn designs, and these critical factors enables the creation of a multi-purpose loudspeaker that is equally at home as a high level stage monitor as it is in smaller front of house applications.

The 18 mm birch plywood enclosure comes equipped with multiple M8 flying points, integral pole mount socket and Powerdrive type 100 flyplate to suit both portable and permanently installed applications. Due to its asymmetrical shape the Stasys 4 can be used at many different angles. The high quality internal passive crossover network can be bypassed for optimum performance in bi-amped mode, and input and link through connections are provided by two Neutrik speakON™ NL4 connectors.

Large Scale Touring

There’s a lot more to delivering great festival and arena sound to large audiences than just audio quality – truck pack, transportation and handling, reduced system size, ease and speed of rigging, optimally configured amplifier packages and intelligent processing – these qualities are found in abundance in Void’s tour sound loudspeaker systems.
