NOTES:
• This is the exact mounting depth of the driver, and does not include provisions for air flow from the vented pole piece. Clarion recommends at least 1” of clearance behind the driver to facilitate air flow and proper cooling.
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.
