EMIT Tweeter Repair
 

I saw this service listed on another site. I'm just passing the info along - I don't anything about this vendor.

Thank you!

If I ever need it done, I hope he also does the rectangular EMITs.

There were several versions of the EMIT diaphragms each with different frequency responses. The EMITs he has pictured are different from the ones used in the IRS V's. I still have a few dozen new ones left from when Harmon was closing them out but the best engineer that I have found for repairs is Cory Johnson. His contact information is here on the site for AA members to access. Cory's work was checked by Arnie Nudell, the original designer, who said the system with his drivers was the best IRS V that he had ever heard. The system is in Paul McGowen's music room one at PS Audio as of this writing. The EMIT-K's used in the IRS V were the best version. In fact, Infinity used to sell an upgrade kit to convert older systems to the EMIT-K's.

I am looking for someone to refurbish the crossovers on a vintage pair of Infinity Reference IIb's, but I can't find anything here that lists Cory Johnson's information?

Just curious, I have some RS4.5's and the EMIM's need some work. I know Graz has replacement diaphragms for them, but very expensive. Is there anyone in the US I could send these drivers to and have them serviced?
