But I can address this specific concern.
Drivers screwed onto MDF baffles will become loose if you keep undoing and re-fastening them, because the self-tapped threads they create in the MDF eventually crumbles away. But if you screw something down with big enough screws to the right torque and leave it alone, I see no reason why they should come loose in normal usage. As for bolts coming loose - not if you use lock washers or nyloc nuts. And not if the bolts are big enough and tightened to the correct torque. Think about the wheels on your car, which are subject to at least as much vibration as drive units in a speaker - do they come loose? Only if you fail to tighten them properly. (I speak from personal experience having once forgotten to tighten some wheel nuts. Fortunately I was travelling in a straight line at low speed when the wheel came off. And luckily the brake disk acted as a "backup" and stopped the suspension components from crashing into the ground!). ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=98249 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
