Yes. I have a project I'll be working on (hopefully) where I'll really be stretching the limits before the natural cut-off slope comes into play. The -3dB points are fine, it's just getting them to blend together properly. If it works, this'll really rock.

Now, I've seen plenty of times where it's been said that it's very nice to have the crossover about 1 octave away from the -3dB point. Does that still hold for the 24 (or even 48) as it is much quieter at the octave away when compared to the 12 db/octave slope? Basically I'm wondering if I could get it at least 10db down (or more) before the natural cut-off slope begins to have an effect, if it would really make a much of a difference in the response. Like does the 24 dB/octave slope need to hit 24 dB down, or would 12dB down where the natural cut-off comes into play be enough as this is the drop-off is the same amount as with the 12 db/octave slope. It's just steeper. I'm asking because I think it's going to be close enough where that could make a difference.
