I've just received a couple of replacment M3 In-Ceiling speakers and noticed a few changes that make them better than the initial versions I had received:
1) Speaker Terminals are now a spring loaded type (but can still take plugs). This is good as the old ones were screw down types and I found these could rattle
2) The Allen Bolts for the clamping system is now different to those holding the speaker assembly (so you can not accidentally tighten the wrong ones)
3) The Clamps are now longer so they work better with different thickness sheeting. Unfortunately, it is still not long enough to clamp the speaker on 10mm Gyprock used in Australia. I pack these out with a double thickness of mounting tape or else they would rattle.
