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.
The EMIM's in the RS2.5 are used in the frequency range from 300 - 5000 Hz.

The German replacements are, unfortunately, quite inferior. They are of a substandard material (coloured) and are not capable of the same frequency response. Remember the original (pre kappa) EMITs are capable of reproducing frequencies in the near 40Ks, and the SEMITS well above that. Many of the Reference series Infinity's were crossed at 150Hz (adjustable using the electronic active crossover), and these units cannot take the load. I offer this not as opinion, but as experience. Your best bet is to order a replacement ribbon from Genesis Technologies. Yes, it is expensive, but it uses the neo magnets as well as the Kapton diaphragm used in the EMITS, SEMITS, EMIT-Rs, and L-EMIMs.
