Acousti-Wool
Russ Andrews Acousti-Wool is the natural alternative to synthetic foam commonly used in loudspeaker cabinets.
Supplied as a single sheet, Acousti-Wool can be cut up or can be folded and lightly packed into the speaker cabinet (remove the drivers carefully to get access to them if required). As a very rough guide, you'll need about 1-2 sheets per medium-sized bookshelf speaker and 3-4 sheets per medium-sized floorstanding speaker. The sheets can be easily cut to size if required with a large pair of scissors or a scalloped knife.
TIP: Cutting is best done outside to avoid stray wool fibres getting everywhere.
Our Opinion
Russ Andrews Acousti-Wool is the natural alternative to synthetic foam commonly used in loudspeaker cabinets to provide acoustic damping. Synthetic foam is cheap, easy to handle but provides relatively poor acoustic damping - it doesn't attenuate some frequencies, meaning that they reflect back towards the drive unit. Foam has a distinctive sonic colouration which is undesirable.
Acousti-Wool is ideal to replace foam. It's completely natural, effective at absorbing a wide range of frequencies and, being supplied in sheets is easy to use, giving a clear and natural sound.

"Acousti-Wool"
The introduction of this additional damping to an already well panel damped enclosure rendered speech in particular clearer and greatly reduced that chesty cardboard colouration you often find in bass boosted FM radio transmission. It also improved the sound quality throughout the bass mid range. Very pleased that I decided to give it a go.

"Do It Now :-)"
This was the final step in upgrading my Spendor A5 speakers. Previous upgrades were to the crossover components (capacitors, inductors and resistors), internal cables and lower profile bolts. The wool made a big difference to clarity and precision of sound.

"Really Good Stuff"
Using acousti-wool in my venerable Spendor BC1 speakers has finally cured a long standing brittleness in the top end.I should have done this years ago.

"Great Difference In Acoustic Characteristic"
The difference between foam and wool lays in the fact, that the wool´s fiber naturaly is filled with air and the synthetic foam´s fiber is solid. The wool´s fiber absorb / damping the reflections instead of returning them.
