Contamination of Electronics
Small foam particles can settle on amplifier boards, power supplies, connectors and wiring.
Bang & Olufsen Beolab isolation materials protect internal speaker components, control vibration and help preserve reliable sound performance. In models such as Beolab 2500, Beolab 4000, Beolab 6000 and Beolab 8000, the original damping foam can deteriorate over time and should be replaced before particles damage the amplifier or power-supply electronics.
The original foam inside some classic Beolab speakers can become sticky, brittle or crumble into small particles. The debris can spread around internal boards, connectors and amplifier components, increasing the risk of corrosion, electrical faults and permanent damage.
Replacing old foam is a preventive repair that can help protect the speaker before deterioration causes larger and more expensive faults.
Small foam particles can settle on amplifier boards, power supplies, connectors and wiring.
Degraded material may retain moisture or leave residue around sensitive electronic components.
Damaged or missing damping material can affect internal resonances and the intended acoustic behaviour.
Contamination and vibration can contribute to noise, distortion, unstable operation or channel failure.
Foam deterioration around amplifier and power-supply sections can increase the risk of expensive electronic damage.
If the problem is ignored, a working speaker may eventually lose sound or stop powering on correctly.
Replacing the isolation material requires careful disassembly, complete removal of the deteriorated foam and inspection of the internal electronics before new material is installed.
Choose the correct model-specific damping and isolation material. The current products and prices below are based on the available replacement kits listed by Kose Trading.

The issue is commonly associated with models including Beolab 2500, Beolab 4000, Beolab 6000 and Beolab 8000. The condition depends on age, storage and previous repairs.
Yes. Degraded foam can contaminate internal electronics and may contribute to corrosion, unstable operation or component failure.
Preventive replacement may be sensible when the original foam has started to break down. Addressing it early can reduce the risk of more expensive damage.
Experienced DIY users may be able to complete the work using the correct manual and repair guide. Disconnect the speaker from power and avoid touching charged power-supply components.
Yes. Contact Kose Trading if you prefer to send the amplifier chassis or complete speaker for inspection, cleaning and refurbishment.
Replace deteriorated foam before it spreads around the internal electronics. Order the correct isolation material or contact Kose Trading for professional assistance.
