Take your Heresy or Heresy II to the next level.

Select a tweeter

Select your tweeter. I have the Eliptrac HF available. The original tweeter lens used in the Super Heresy.  


Driver Selection: B&C DE-120, DE-110 , DE-10

Celestion CDX1-1412

In testing - Eminence  ASD1001



There are several other tweeters available. Dave Ault, Mike Boxler and Crites Speakers to name a few.

Select a mid-horn

15

Select your mid-horn. I have 2 horns to choose from the Fastrac FT701 for Heresy 1 and FT701-2 with K52 adapter for Heresy II. 


The mid-horn replacement may take the Super Heresy to Version 3.0


Select a port

Select a port. I am considering a 3d printed port  properly sized to install with a hole saw.


 Mike Boxler has a great 3d printed port for Heresy  2 that integrates the binding posts - such a good idea!
