Test Tone Method (Beginner-Friendly): * Connect the woofer to your amplifier with the cone facing up on a workbench. * Play a 30Hz test tone at a low volume. * Apply glue to the metal basket. * Lower the cone into place while the test tone plays.

This allows for real-time adjustment and is a great option for beginners. 6. Final Assembly: Once the glue is fully cured, reattach the woofer to the cabinet, making sure the cone moves freely without any rub.
