Your Sunfire Subwoofer should reach
you in perfect condition. If you do notice
any shipping damage, please contact
your Sunfire Dealer immediately.
Gently lift out the unit and remove all
the packing material. It is important to
save all the packing materials and the
box in case your subwoofer ever needs
to be moved or shipped for repair.
Make sure that you keep your sales
receipt. It is the only way to establish the
duration of your Limited Warranty and it
may come in useful for insurance
purposes.
Please take a moment to fill out and
mail the Sunfire Warranty Registration
card. Also read the serial number located
on the control panel and record it here:

Dear Friend:
Thank you for purchasing my Sunfire
True Subwoofer MK IV. 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 tracking
downconverter and its long throw, high
back-electromotive force driver. Taken
together, they provide this subwoofer
with as much bass as you could get from
several 15 inch drivers mounted in a
cabinet the size of a small refrigerator.

Care
To maintain the speaker cabinet’s
finish, first unplug the power cord and
then use a soft, slightly dampened cloth
to clean the surfaces and finish off with a
dry cloth.
To keep the large rubber surrounds
soft and supple for 20 years or more,
treat them with MINK OIL, available at
most shoe repair stores. Rub a generous
amount into the surrounds with a soft
cloth about once a year (more often if
you live in a dry climate).
If your Sunfire Subwoofer needs
servicing, please read the Troubleshoot-
ing section on page 17. If a problem still
persists, contact your nearest authorized
Sunfire Dealer.
