User's Manual

Dear Valued Customer,

Congratulation on your choice of the SUB-80X self powered subwoofer system,
one of Earthquake's newest designs in bass reproduction units.

With an integral high-power amplifier - 150 Watts, the SUB-80X subwoofer
combines tight bass extension with high output levels. Acoustically, it is designed
to match typical satellite speaker systems to enhance the over all sound quality
and performance of your system.
