Dear Friend:

Thank you for purchasing my Sun

Þ

 re 

True Subwoofer EQ. I hope you enjoy 
it and the music it makes as much as I 
have enjoyed creating it for you.

The big breakthrough features of 

the subwoofer are its uncanny track-
ing downconverter, its long throw, high 
back-electromotive force driver, and its 
fully automatic room equalizer. Taken 
together, they provide this sub woof er with 
as much bass as you could get from sev-
eral 15 inch drivers mount ed in a cabinet 
the size of a small re frig er a tor.

Introduction

ish, 

Þ

 rst unplug the power cord and then 

use a soft cloth to clean the sur fac es.

To keep the large rubber surrounds soft 

and supple for 20 years or more, treat 
them with MINK OIL, avail able at most 
shoe repair stores. Unplug the power 
cord, and rub a generous amount into the 
surrounds with a soft cloth about once 
a year (more often if you live in a dry 
climate).
