Post Subject: Wet/Dry ™ configuration for midbass.Posted by Romy the Cat on: 10/10/2017
Say whatever you want but some of the vintage drivers has
it. Not all of them but some of them do and the question how to get it. I
always has been an enthusiast of midbass horn and I am very much the enthusiast
now but there are some topological limitations, in my view, that might prevent
a midbass to get “it”. I always witnessed it, including with my former midbass
horn, which was probably the best topological and implementation decision I
have seen for a while. For sure a midbass horn can get the softness that is
unmatched by anything else out there, there are no direct radiators can play as
soft as a good midbass horn can. However, since the driver in midbass horn is
locked in compression chamber, and this is only my proposition, the midbass
horn always has a difficulty to do “it”.
What is “it”? If you listen the recording of Chicago
Symphony. The period of later Reiner and the most
prominent the Georg Solti’s period then you can’t note a very distinct brass coming
from CSO. Now, let live aside the musical value of that brass, that forwarding sounding
distinct brass unfortunately-identical for all music. We are not taking about
music but rather about sound and the ability of a playback to reproduce sound
in a way how Solti’s brass sounded. The Chicago bass of that time was unique.
It was supper dry and very prominent. The problem with that brass that it sounded
was so fucking beautiful that is acted like a woman with a super cute legs in
super short mini-skirt: no matter how much you move you wife but it is not
possible not to “glance” in there…
Within audio installations that brass is VERY hard to get.
The only time I witnessed it in audio was from “some” hard suspended, paper
spider/cone vintage with low ultra-low exertion and high sensitivity. Some of
these drivers can do spectacular transient with Sahara-like dryness and being
driven by very lightly loaded amp and playing 5-6dB louder than necessary there
drivers could throw a spectacular super dry and super contrasty Solti’s mib-bass.
Those drivers would not play soft. You need horn to get that. If you want most and
noble mibass of let say Czech Philharmonic circa 60s then you need horn. How to
combine them together?
Well, just plain and simple: combine them together. Here I proposed a new topology:
Wet/Dry configuration for midbass. By the power invested in me I declared the topology
is a registered trademark.
So, the Wet/Dry midbass configuration implies a combination
of preferably less compromised midbass horn working along with a midbass direct
radiator. The direct radiator AND horn cover the same octave and time-aligned.
The out of direct radiator juts enough to dry out the midbass only when music
is called upon it.
The idea is freely shared with anybody who dare to reach for
