Morning
@PENG! Person I think I would try to raise 20 by about 5 and try to slope it down to 200. Seems like whenever I have simply raised the sub channel, it creates a steep drop off at the XO. Makes it seem very bass heavy. And not in a good way. I’d also like to see the graphs up to 20k to see the whole relationship.
What are your thoughts?
Agreed, he is now in a good position to shape the curve between 20 and 200 Hz, but instead of "raising", it may be easier to lower 15 to say 160 Hz, such as making cuts as follow:
15 Hz....................... +1
32 Hz....................... -2
80 Hz........................-2
120 Hz.................... -4
160 Hz.................... -3.5
200 Hz................... -3.5
After that, increase sub1 and sub2 by +3.5 each, and see what happens. The idea is, the boosts and cuts between 15 and 200 Hz if to get that upward slope towards 15 Hz that apparently most people like, and then the subwoofer levels increase is to restore the levels to those before the cut, and keep them a little higher than the level from 200 Hz and up.
My concern with raising the lower base from 20 Hz is that it would mess things up and may even cause instability. Cuts are much more predictable. Problem is, I think he can no longer apply more cuts as he's at the -12 limit (by Ratbuddssey for some reason), so the 32 Hz cut won't be possible. That's not a big deal though, it wouldn't hurt to have it a little "hotter" at that low frequency.
It is still hard to predict, so your suggestion may be better, he can try both approach if he has time. Or just leave it the way it is, if he happens to be like me, who actually prefer the flatter bass response that is actually better in terms of "accuracy/neutrality".
