KEF Q150 T/S parameters

Hi all
Any word on the progress of the original post? (TL enclosure)
AND...
Does anyone know a non-destructive way to open up Q150 boxes?
I was intending to add some damping to mine, but they seem to be totally sealed: the only thing that comes off is the terminal plate. No screws on the rear, and I hesitate to try to pry the surround ring off the baffle.
Thanks if you can help
Phil
