WM4 uses two 320 mm (12") low frequency cone with 75 mm (3") voice coil with double silicon demodulation rings and Neodimyium magnet. The high frequency drivers of 75 mm (3") Titanium voice coiland neodimyum magnet on asimmetrical wave guide provides higher output and lower distortion plus enhanced power handling capabilities for better performance in both touring applications. LSS's advanced crossover incuded professional protection of HF. The WM4 offers a switchable powering mode: passive operation using the internal crossover filter network or biamplified operation.

APPLICATION

The WM4 was designed to support the widest possible range of pro audio applications. Is ideal for stage monitoring applications high output vocal presence and neutral balanced sound. WM4 use two woofers of 320 mm an 75mm HF driver on asimmetrical wave guide.
