In Reply to: Heresey upgrade for a P-trap posted by jim denton on December 19, 2003 at 12:17:10:

A P-trap consists of a 3 uF cap wired in parallel to a 0.1 mH choke, then the entire thing gets wired in series with the Heresy's mid-horn. This will only do good on the older type horns in the Heresy 1's. Won't work in the Heresy 2's.
There is discussion on this in the archives on the Klipsch forum. Use the sear engine there and look up P trap. It worked last time I tried it. Also, check the updating older speakers section for other Heresy mods.
