Audi Do! In this great galactic arena, my leviathan gargantuan (or, Lilliputian) request is that I'm shopping for a functioning Linaeum monopole tweeter (ET5) for an Optimus LX4 loudspeaker. I have a beloved pair of LX4's, but alas one tweeter is ready for the recycle bin...Thank You, Thank You very much. I AM leaving the building (site.)
