Here is a 3-point plan for taking speakers out of storage. Moisture is our enemy.

1. Visual Inspection

• Check for condensation, mould or rodent activity.
• Inspect connectors, cables and ports for corrosion and rigidity.
• Ensure ports and vents are clean and clear of restrictions.
• If you see dust or dirt, clean it away gently.
• Consider using an airline to blow dust away gently.

2. Internal Checks

• Open the front grill and inspect for visible damage.
• Spread fingers and gently press on the paper cone for unrestricted movement.
• Remove the back panel and remove and remake all connections.
• Tighten all bolts, fixings, screws and mounts. Drivers on the diagonal.

3. Powering on

• Condition the speakers for 24 hours at 19 Degrees Celsius (room temperature).
• Test resistance with a multi-meter to ensure proper continuity.
• Start at low volume and listen for distortion, rattling, or missing frequencies.
• Check for buzzing, distortion, or imbalances between speakers.
• Ensure horns, tweeters, and subs are all functioning correctly.
