3. Subwoofer Break-In Period

All new speakers require some amount of time to break in. Depending on the applica­tion, this may take between one and four weeks. To accelerate this process, you can
manually ‘break in’ your subwoofer before installing it. With the subwoofer sitting on
a scratch-resistant surface, connect it to an amplifier and play a 25Hz sine wave at a
level of 10V (8V for SFW) for a period of four to six hours. If you have any questions or
concerns, please do not hesitate to contact your Authorized Clarion Dealer.
