In the Thread: My new “New” listening room, 2024
Post Subject: Back to Macondo Axioms,Posted by Romy the Cat on: 5/22/2024
Head today to another local audio guy who listen to my new
configuration. The reaction was fascinating. He was asking: what the hell I had
done to midrange? Of course, I did nothing, but the question was very accurate.
A lower mid-range changed very dramatically and became almost new. So, what, in
fact, was changed? Previously, my midbass channels ran 78 Hertz high-pass
filter. In addition, it was complimented by a 130Hz high pass filter, as my ear
told me that the decay of the mid-based channel was too long. As I added two
parallel drivers, the output stage was significantly more loaded, and the
mid-base decade became less prominent. This permitted me to remove the large
speaker-level coil that formed the 130 Hertz high pass filter. Now, I could run
my meat best in the same polarity with my upper base horn and my mid-range, so,
essentially, I have removed phrasal distortions from my integration between my
mid-base and upper channels. Effectively, I returned to my Macondo Axioms,
permitting drivers to run strictly first-order filters with minimum phase. The what's
formatting part that the audio guy who visited me four days back, who else very
much familiar with all my audio configurations over the last 20 years told me
that in the way my sound now reminds me what I had 20 years ago in my Boston
apartment. At that time, my premature version of Macondo did comply with my
Macondo axioms, and at that time, I ran only phase-consistent filters. Even if
I used 2nd order for my woofer towers, they were line level and used a very
precise Bessel curve, which is time constant. It is beautiful that the person
was able to detect the same Sonic signature that is strictly derived from
time-constant channel integrations. I know it is an irrelevant post for most of
you but for somebody who at the standard and can hear that is a spectacular
evidence of Macondo axioms righteousness and a great topology to follow.
