Insulation behind ceiling speakers?

[4Q]

I'm installing a pair of Lithe Audio speakers in the ceiling of a posh shed I'm building (build thread coming soon) and the void in the ceiling is filled with mineral wool insulation. Should I push the insulation back to create a void or doesn't it matter much from a sound point of view?

Ideally you should contact the manufacturer and ask what will sound best. They may say it is fine, or they may see it needs x cubic feet of air around it.

I always go for closed back speakers so less to worry about.

I'll contact them tomorrow. Cheers

Over time the dust could cause an issue if the speakers dont have any 'back-can' or protection.

You could use a simple fire hood or a hoody which also provides some sound insulation.

Push it back a bit, no need for a massive gap just give it some space.

Using a fire hood is preferred..

Lithe Audio's electronics are encased all-round so shouldn't have any dust issues.

Enjoy them! Great speakers...!

I had a reply from lithe and they said insulation shouldn't make a difference but also recommended a hood. I tried with the insulation pushed back about a foot around each speaker anyway and it did make the bass sound better at high volume.
