In the Thread: The ULF cannel for my new listening room.
Post Subject: My new IB, the first blood, good one.Posted by Romy the Cat on: 9/15/2018
This mooring I decided to play with my infinite baffle. The
mess with my analog crossover hat was calibrate for my old listening room gave
me bad IB taste. I bought used stinky Behringer DCX2496 Ultradrive Pro crossover
for $100 to find my new crossover point. The Behringer is a spectacular machine
with all imaginable flexibility and very fast making all possible experiments
and listening the results I recognized that I need to disconnect my woofer to
and to run IB all the way up to my midbass channel. So, I ended up preliminary
with somewhere around 52-56Hz, second order Bessel of cause. There is a lot of flexibility
and ease to make all possible adjustments, I had a LOT of fun to shape my
sound, I did no measurement and played purely by ears. For, the things will be revised
as some measurement be made.
I am quite surprised with the sound I go. It is very good
and it was VERY easy, it was kind of insulting how easy it was. The bass now
fill the whole room very evenly and the sweet spot grew very dramatically. The midbass
got surprisingly cleaned up, become more granular, lost some compression and become
much more open. The lower octave is truly infinite, very solid and very nicely
mixed with the rest of the sound, I am very surprised how easy it all come
together. Probably the biggest beneficially of all is imaging, it is kind of become
insane. I spend the whole morning like a pig in shit, swimming with my new
sound. Even Amy flocked to my listening room and we did some listening and calibrations
together.
Now, here is what I need. I mist like I stay with 2nd
order and I need to nail down the specific frequency I will end up, it is
important do not confuse frequency with volume. I need figure out if it worth for me to get
rid of my bass line-arrays and to give my Midbass Vitavoxes for a 1/3 octave
lower. I need to review the system installation in the room from imaging
perspective, this is a whole new imaging game and I am willing to cash everything
that comes free with this game. I need to implement the final crossover at
analog level. I do not know if it will be in the amp made as passive line-level
or it will be fully active with tube buffer. The second order is very simple
filter and might end up with passive line-level but I do not know if my stinky
SS amp will sound Ok in bass. As now despite all superbly positive thing in the
sound all bass notes basically the same: courtesy to the digital crossover and
SS amplifier. I need to render my final filter at analog level and see where I
will end up with lower octave notes discrimination. I might end up with some
kind of PP DSET around 845 or 211 tube but at this point it would be looking
too far…Rerurn to Romy the Cat's Site
