Post Subject: What to expect from ULF channel?Posted by Romy the Cat on: 10/28/2010

Since I finalized how my midbass horn handles decay the only things left in my playback is to set the right level and cut off point of my ULF channel. Formerly I did set it up for 35Hz, second order and it was fine as a temporary setting. However in the light of improvements in midbass upper knee decay the new way to use ULF need to be devised. Last night I span some time to run ULF channel up and down in frequency and volume but frankly I did not find the configuration that I feel comfortable.

I need to admit that I never ever heard any properly implemented ULF channels. Yes, I have seen very good ULF channels but if I had change to hear them then they sound always too low to me. I know very much how I would like ULF to sound but I do not get this effect with my ULF so far. It feels like second order is too shallow for my ULF but if I go higher then I lose proper integration between ULF and midbass.

I think the whole idea of how I use the ULF and what my ULF is needed to be de reviewed. I do know what sound I would like to get but I do not know all expressive tools of ULF. My former experiments with ULF were very successful but then I was playing with tratrix upperbass. Now my lower horn is not tratrix but hyperbolic and I need to say that hyperbolic curves decays much slower and with much more integration complexity then tratrix. So, I need to think and to revise how I think my ULF might be used.
