Heresy Crites updates

Possibly nothing. Have you been listening to them? Are there any problems? One thing many people do is utilize a sub with Heresy's. I don't use a a sub with mine. They are simply hooked up to a tube receiver, and I like them fine that way. I put in a crossover (recap) for the E2 networks in them.

IMO, you should listen to them and enjoy them before thinking they need improved. They are very good sounding speakers.

The caps are usually about all that most need. You can remove the backs, clean all driver and crossover connections and re-tighten. And put a strip of speaker gasket tape on the rear panel braces (leave no gaps...) to make sure the cabinet is sealed. Generally that will improve the bass. Over the years they "leak" and they are not supposed to do that....

Other things (in descending order of cheap but effective)

  • unscrew the woofers and rotate them 180 degrees. Over the years, the basket frame sags from gravity.
  • replace the gasket between the K-55 driver and the horn. It's located in the threaded area and it's probably dried out.
  • consider replacing the K-77 tweeters with CT-125's. Drop in, and they are very good.
  • consider replacing the K-22 woofers with the K-28's (Heresy-III types). Much better bass response. Or the CW-1228's from Bob.
  • consider having Bob re-working the Type E/E2 crossover to be a Type E/4500. This takes advantage of the CT-125 tweeter's response curve.

I've got a pair of Heresy speakers modified precisely as groomie lines out and the sound is very pleasing.
