Re: Soundwaves are compressed/decompressed air...

Trumpets, kick drums and voices are all waves of compressed and decompressed air propagating out from the source. They are not like an object in motion or a wind blowing. Sound propagates as the molecules crash into each other and transfer their energy. Sort of like a compression wave in a slinky toy. The wave travels through the slinky, but the slinky does not go anywhere. The sound wave is a series of high and low pressure rings propogating out. If the music caused the air to blow like wind we would all look like that old Memorex ad with the guy sitting in the chair in front of his stereo with his hair blowing back. LOL (you can feel wind from bass ports, but that is different)

I'm not familiar with how Quads work. Don't they use two charged screens that push and pull the diaphragm back and forth? Magnepans use wires glued to a mylar diaphragm. One side has many thin vertical magnets. The signal causes the wires to attract/repel to the magnets, vibrating the mylar. Since there are magnets on only one side, the forces changes as the distance does. Wires on Magnepans do come loose. They peel off the mylar eventually. This is from time, humidity and poor adhesive.
