Capacitors - Bypassing vs. Film & Foil in Crossover

[milton10]

I just found out the problem with jagged highs were due to my rear

speakers (this is a HT setup), not my crossover capacitors. Up

until last week, I have been running KG-1's as rears. Now I have

replaced them with circa 1979 Heresy's and Shazam, the

problem has disappeared. It seems that the KG-1's are not as

smooth and tend to beam the rear channel information even though they

sound very close to the Heresy's with white or pink noise tests AND have been properly

set up with a Sound Level Meter. For some reason, the rears sound

ever so slightly different from the Fronts/Center and really stand

out. As soon as I added the Heresy's as rears the problem was

solved. Now I have seamless transitions from front to back and

soundtracks seem to "float" in the room rather than sound like its

coming from 5 different speakers. The result is NOT subtle - even

my other half (whom has lead ears) could hear the difference clearly.

At any rate, I did order new Kimber caps for my system (after all the

new rears need to have their caps upgraded) however, I did order them

for all 5 speakers. I 86th the idea of the Audiocaps and went

with all Kimbers to avoid pushing the voicing any more forward.

To anyone wondering if 5 identical speakers will make a difference in

HT sound, I can attest to the MAJOR difference in smoothness and

soundstage. I say this because I think that more often than not,

rear speakers in an HT setup are neglected since there is not as much

soundtrack and dialog passes through them - which is a mistake. I

will post the results when I have upgraded all my caps to the Kimbers.

Thanks to everyone who contributed to this thread!
