Limited Warranty

Sunfire Corporation is proud of its

products which have been built with care
using advanced technology and premium
component parts. Your unit has been
crafted to perform properly for many
years. Sunfire Corporation offers the
following Warranty to you, the owner of a
new Sunfire product:

The Sunfire Corporation Warranty for

the True Subwoofer Signature is in effect
for TWO years from the date of original
retail purchase. The Sunfire Corporation
Warranty covers defects in materials and
workmanship. The following, however,
are excluded:

a)

Damage caused during shipment.

b)

Damage caused by accident,
misuse, abuse of operation
contrary to the instructions
specified in the Sunfire Corporation
user’s manual

c)

Units where the serial number has
been defaced, modified or
removed,

d)

Damage resulting from modifica-
tion or attempted repair by any
person not authorized in writing by
Sunfire Corporation.

The Sunfire Corporation Warranty

extends to the original owner or
subsequent owner(s) during the two year
warranty period so long as the original
dated purchase receipt is presented
whenever warranty service is required.

All implied warranties, including

warranties or merchantability and fitness
for particular purposes, are limited in
duration to the two year length of this
Warranty, unless otherwise provided by
state law.

Sunfire Corporation’s liability is limited

to the repair or replacement, at our
option, of any defective product and shall
not in any event include property or any
other incidental or consequential

damages which may result from the
failure of this product.

Some states do not allow limitations on

how long an implied warranty lasts and/or
do not allow the exclusion or limitation of
incidental or consequential damages, so
the above limitations or exclusions may not
apply to you.

This Warranty gives you specific legal

rights, and you may also have other
rights which vary from state to state. We
suggest that you attach your purchase
receipt to this Warranty and keep these
in a safe place. Thank you for your
choice of a Sunfire Corporation product.
