To evrybody who is looking for EMIM and EMIT replacements: "Layne Audio" (615)298-4124 sells modern German-designed replacements. These are made of different material which is not moisture absorbent, they are more efficient and a lot faster and clearer. They are 4 ohm drivers, physical size: 3.5" by 7 7/8" with working area of 2.5" by 6 7/8". And they are $69 a pop (!) dropping to $64 for multiples. You MAY need to increase your midrange drive resistor to compensate for slightly higher efficiency, but may be not, especially if you have a mid control. They also have tweeters at $49 ea. Say "Halleluya!" Rgds, Mark, Infinity 4.5, still one fo the best speakers in the world.
