I had a couple of pairs of these around 1980. If it were me I would either leave it as is or add some more modern damping material to give a similar effect. It was designed to have a certain amount of damping; removing some or all will certainly change the sound but there is no gurantee it will sound better. Be sure to change the posts as well.
B&W DM6 Wadding
I am ready to replace the caps and wires in the DM6. I will make it possible to bi-amp. I will also bypass the fuse. However, I am not sure if I should reduce the wadding in the box. If I do, should I just do it in the bass compartment or in the mid and tweeter compartment too? Would doing it make the music more lively or what? Thanks in advance.
