Energy 22 EPI Hybrid

I have a pair of Energy 22's with a set of blown tweeters. Finding replacement tweeters for Energy 22's is getting more and more difficult. There was a Company out of Halifax called ABI Tech that bought all the machines from API to rebuild the tweeters, but Chris Coote has disappeared.

Only a few tweeters will fit into the 5 3/8 inch cut out and have the ability to be crossed over at 1500Hz.

An EPI or Epicure tweeter is one of those tweeters. The other would be Polydax/Audax T-103 with the big plate from a set of Infinity 5000A speakers. One could buy a Dayton Audio or Vifa Dual Ring tweeter but the cut out would have to be made smaller.

The EPI tweeter is far more accessible from EBAY and for far cheaper. From what I know the Energy 22 is crossed over at 1500Hz. on a 3rd.  order for the tweeter and a 1st. order for the woofer. There is also a resistor in line to bring the output down. I just did a straight swap of the tweeter and left the original crossover intact.

I like the sound of the EPI tweeter when it is crossed over at 1800Hz. with a simple 1st. order 10uf capacitor. The 3rd. order crossover straightens the tweeter up and does not let it be as airy. It sounds good and all but it is much more polite.

The bottom end is much fuller and warmer given the cabinet size and the quality of the 7 inch woofer than you would find in an EPI 100 speaker.

It would be worth while to source a pair of Polyday/Audax T-103 tweeters to test out also.
