WE WANT YOU LISTENING FOR A LIFETIME

Dear Customer,
Selecting fine audio equipment such as the speakers you’ve just purchased is only the start of your musi-
cal enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment 
offers. PowerBass and the Consumer Electronics Association (CEA) want you to get the most out of your 
equipment by playing at a safe level. One that lets the sound come through loud and clear without annoy-
ing, blaring or distortion- and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing " comfort level" adapts to higher volumes of sound. So 
what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your 
equipment at a safe level BEFORE your hearing adapts.

PowerBass and the CEA want you to listening for a lifetime!
