Hi, don't often enter here, usually Subwoofer Forum. But, I got excited about some bass I was getting from my mains, (my sub being down), I cranked up the bass hit the Loudness, and one speaker started distorting.
Investigation found a vibrating cab, the back panel, I thought, was plastic covered, NOT! I removed the woofer and the stuffing and found my Mordaunt Short MS 40's look like this...

Is this good practise in manufacturing of cabinets. Surely the back panel should be Dense?
