The ULF cannel for my new listening room.

My Placete preamp was sitting in Idaho for update for a
long time, so there was not a lot of audio activity lately. Also, the last few
month there was a lot of things going on in my life that severely compromised my
audio rotation. It is summer and small kids spend a lot of time outside that request
a lot if not my attention but at least presence. The property needed to be open
for summer business and there was a lot of work need to be done. The idiot-landscaper
destroyed grass at our lawn that required me to learn about the damn grass growing
and fix it. I undertook a large construction project in our home that required
a lot of planning and supervision, it is still going one and hopefully will be
over in a week or two. I fired one of my long term helper and another good long
term helper ended up in jail, so with a lot of property maintenance tasks I ended
up to involved much more then I would like to. Our nanny tenure is expired and
new one need to be acquired. I undertook a major transition from .Net to Golang
in my professional life. Amy’s parents moved right next to us, which is blessing
and curse. Amy and I decided to change to that dreadful “healthy life style”, whatever
bloody thing it is, but hopefully it will keep us available for each other and
to our kids slightly longer. I turn 50 years old in beginning of month, I can write
a fucking book how I feel about it! Anyhow, there was zillion other things that
made me kind of “busy” and there was not a lot of audio in my life during the
last few month.
Lately, I go my Placete back, the life looks straitening
up and a few last time I had a long listening session in my listening room I recognize
that I was so much missing these listening experiences. The playback is a good shape, the extra 6dB
from Placete made is even better. The way how I left playback before was a
“smart” setting in my view. The playback do not go too low in term of overall balance,
it has solid mid 30Hz, but it has also no “shit bass” when typically “wrong
means” are used to squeeze bass out of wrong and bass-impotent topologies. The lack of bass is not so notable in my current
playback. In fact the bass is quite good
in my estimation. What is missing is the last feeling of “weight”, the very specific
softness that usually introduced with sub 20Hz response, the softness that warms
the whole sonic presentation and make is so fucking palpable! I had in in my formal listening rooms, I call
it ULF cannel (Ultra Low Frequency) and I do not have it in my current listening
room. Here is how it was done in my last listening room:

When I said that that I left my playback in “smart setting” I meant that
I did not go for ULF by wrong means. You cannot get any proper ULF by bumping room
with LF distortions that come for a running a regular commercial subwoofer. You
cannot put a large Sunfire-like topology with tweaked electronics in use. Well,
you can and you will get the right SPL numbers under 20 but it will be sound
that satisfy only your SPL meter but not you spirit.
So, with this post I am starting to collect my thoughts
about the ULF for my new listening room and hopefully as a result, I will have
it implemented.
