Important information about subwoofers

Subwoofers are designed to reproduce low bass audio signals between 30Hz and 150Hz. Driving them with full frequencies will cause permanent damage, so they should only be operated with a passive low-pass filter, a crossover network, or an active electronic crossover or speaker management system.
