EMIM from 4.5 infinity has anyone rebuilt?

Try this link, they claim they have replacements

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.

Further info on EMIM replacements. Clicking on this link will give you info from manufacturer, as well as lower price than Layne Audio. However I need one question answered: what is the crossover frequency in 4.5 at which EMIMs take over? These GB ribbons only work from 500hz and up, but VMPS who also uses them claim that they go down to 160 hz. ???

Sorry, just noticed the link didn't go thru. It's GR Research, , they sell EMIM replacements for $59 ea. as well as a ton of other speaker parts including many different ribbons. Good luck, Mark.
