Heresy Tweeter Mod

Recommended Posts

Hi, so I’m was looking at the taps on the autoformer and my schematic for E2 crossover 

 

you say to change tap 2 to 1 for the tweeter and 3 to 2 for the squawker...

 

but on mine the tweeter is on 3 and the squawker is on 2...

 

could it be u meant the reverse.. ?

Squawker for 2 to 1 and tweeter from 3 to 2..?

 

see my schematic

 

 

Thx

I didn't notice, but you are right.  Move squawker from 2 to 1, tweeter from 3 to 2.  That will attenuate both by an extra 3db.

Nice!  I, too, am working on my Type E2 crossovers.   First I'll try adding a p-trap to the squawker to try to tame the massive hump around 10.5 kHz.  Hopefully that will reduce some of the top-end brightness.

I just bought a pair of Heresy speakers from 1983. Step one, what are the stiffening mods?

Never heard of that mod. Unnecessary I suppose.

what is wrong with these speakers ----if there is none , leave them as is ---Heresy cabs were used in the Pro series and even then with way more power , 0 vibrations

The back is too thin and will resonate. You can keep the original and replace it with some 3/4 inch ply, or mount a strip diagonally  to stop the vibration.
