The 380 mm (15") low frequency cone with 75 mm (3") voice coil and 44 mm (1.75") voice coil high frequency compression driver provides higher output and lower distortion plus enhanced power handling capabilities for better performance in both portable and permanently installed applications. LSS's advanced crossover included professional protection of HF. The SP640 offers a switchable powering mode:full range or Bi-Amp passive operation using the internal crossover filter network.

APPLICATION

The SP640 was designed to support the widest possible range of pro audio applications.While ideal for distributed systems, the 13° per side trapezoid angles match the 90° horizontal coverage pattern allowing the creation of tight packed clusters. The pole mount cup and balance-optimized handles allow for quick and easy load-in for portable use. Its high output capabilities let it act as a main system for smaller concert or portable A/V events or even provide front or side fill for concert touring applications. The comprehensive system mounting points allows safe suspension in permanent installations.
