Post Subject: More thinking about IB and some configuration changesPosted by Romy the Cat on: 9/17/2018
There are few more observations I would like to share after listening
my new IB over this weekend.
The midbass. The midbass channel that is handled by a single
Vitavox 15 driver with use of my new IB became if not more propitiate but at
least more articulate and communicative. I am not sure why but it is quite noticeable.
Since I am planning to stop driving the bass towers from my Mil’q bass channel
I am planning to bring the Milq’s bass channel to drive that Vitavox
driver. This will gives a LOT of opportunity
to pay with loading and to experiment with many other things. Why would believe
that IU will have an extra bass channel in my amplifier! And who would feel
that it is a bad thing!?…

The volume. To my very huge surprise the enter playback to become
to sound MUCH louder at MF. As I moved to this new listening room I am always was
bitching that I have no volume even though the size of my listening room did
not change too much. It made me to get for active gain in preamp in some cases.
With introduction of my IB channel I got
my volume back and subjectively the playback sound now twice louder. Oh, the
glory of ULF channel!!!!
The bass arrays. As much as I love them but for now I am not
planning to use them. The IB gave a very different type of sound and I would
like to get THAT. I would never though that it would come to it and I always expected
to use my bass arrays for bass and IB for ULF, or sub bass. The uniqueness of my
situation is that my IB turned out to run from 5Hz to 120Hz with relatively
flat response, something that I absolutely not expected. So, I was considering
to bring the bass arrays to my basement storage but here is why Amy interjected
and I am not sure how to deal with it now. Amy insisted that the bass arrays
must stay in the listening room as she feel that it looks very pretty. Indeed,
for the woman the size matters…
The crossover. I will be building this week a second order Bessel
40-50Hz crossover with 12AX7 as a buffer after the filter. I am deciding if I need to go with passive
filter or to drive the filter with another active stage. Bothe will work very
well. Dima calculated a filter values for me in passive mode but I wonder if I
get more dynamics in I put juts in from of a filter another 12AX7. I do not
have answer for this question now. Most likely I will put the two tube into the
game and will make a switch that would allow me to defeat the first tube.
