Hello everyone, I did some measuring and listening tests. I have noted that the effect is better with a sharper Low Bass filter. So I sticked to what I had from the begining. I had better results by lowering the low pass cut-off, 48 Hz is good (for the 5L speaker) I have the feeling that the warm tube plugin in between the low pass and the harmonic shifter helps a bit with the harmonic generation. with a 63Hz signal as a test I get 63, 126, 189, 252, the first two are of similar level and about two times (in dB) the other two. Not bad, I suppose. I also have added a High pass filter at the end of the full process, soft (first order, 65 Hz cut-off) The end result is not bad. I also have tested Tim's Spice. I tested alone and inside of the BassMax process. Sorry, I didn't like the result, inside my system. So I will stick to what I have for the time being. Thank you everybody for your appreciated support.
