Hello,
So I am currently tweaking my much loved Heresy I's and I wanted some advice before I seal them up. I listed below the mods I have done so far and what I have left stock. I am VERY happy with the refined sound from the crossover upgrades, bracing, and foaming I have done so far, but the bass just isn't there like it used to be...
Here is a list of what I have done so far:
-Replaced old caps with Audyn and Solen caps (I kept the crossover specs stock)
- Braced the the cabinets (see pictures).
-Made risers (I have vintage solid brass isolation spikes that will go on later)
- Foamed the woofer area (cabinet bottom, sides, and back)
-Placed some polyfill in the bottom area of the cabinets.
-Upgraded the old cinch screw posts with gold plated binding posts (nothing crazy high end, just cheap ones from ebay)
What I left alone:
-All speakers are stock.
-Transformers
-Connectors
-Wires
The area where I really need advice is finding the right amount of foam and polyfill for these speakers. I have a few approaches that maybe someone could help steer me in the right direction.
Approach 1- Remove all or most of the foam and keep the polyfill (My thinking is the foam is stealing cabinet volume and the polyfill is doing a better job of damping anyway)
Approach 2- Remove the foam and fill the cabinet top to bottom with loose polyfill (My thinking being the more polyfill the more the woofer is being tricked into thinking the cabinet is bigger that it is)
I run my Heresy's with a fully restored Fisher 400 tube receiver (30 wpc) and listen to a variety of music.
Thanks for the help!
