Golf Dynaudio Sub Fix

[bonsquibbins]

Good morning,

I have heard a few people reference a 'sub fix' for the Dynaudio system in the Golf. I am struggling to find any info on this using search. Can anyone elaborate on the method and the expected outcomes?

It is removing the speaker from the sub enclosure in spare wheel and stuffing it with acoustic foam don't pack it super tight just fill it up semi firm and replace speaker
Tightens up the bass makes it crisper as the housing the speaker is in is all empty space
