I guess I have found a more or less usable new configuration for ULF channel. It is 28Hz, second order, with slightly raised ULF on the transition slope. It sounds quite good. Well, I am not supposed to say this. It doesn’t sound good but it sound properly. I mean the bass is absolutely properly integrated and present a very rare setting of how a playback bass shall sound. I say very rare because any other setup I heard had too much bass of bass tock over the upper channels. My setup now has absolutely proper “talk” between lower bass, midbass and upperbass, letting all low end channels to shine where they shall. I am absolutely confident that that way how my playback not render bass is how the best orchestra shall sound from the best sits on a house. Do I like the quality of bass that I am getting; do I consider it as a good quality bass? No, I do not.

Even though quantivly and structurally bass is correct but it is not what I am looking. I am looking for “winter frost bass”. I do not know how to explain it but if you were high in mounts and remeber this feeling of early morning burning frost then you know what I mean. My current bass is sourced from one channel, hopefully when I engage the second it will do better. I do not know how bass transparent the Velodyne crossover. I presume that it is the one that east all bass quality. My next step will be to make the 28Hz, second order, passive, line-level before the ULF amp. I hope my preamp will be able to drive it, 7 reactive filter to drive – it is a LOT – very few preamps would handle it.

The location of my ULF channel and not good and I do feel the time alignment discrepancy. I can correct it by phase regulator on the Velodyne crossover but I will not have this option in line-level passive crossover. I have some options and some tricks how I can deal with the situation, it will be later. Still, as now, I have very much usable setting with very proper bass. It is not the bass of my dream but it is not wrong bass and this already a LOT.
