[QUOTE="Doxquzme, post: 8848864, member: 689267"] No sense in arguing, the software has helped me do just that, many, many times. A smaller box can be tuned to the same lower frequency in this scenario, there are limits to this, sure, physically, but not within the differences we are talking about here. Optimal is the key, not bigger or smaller. If you can tune to the same frequency in a smaller box or lower Fb in the same size box, the entire band will look different, usually a benefit in a car environment when you employ either calculations using a SSF. When you apply a SSF prior to amplification, (an active filter as we are discussing here) BASS box pro still allows one to keep the tuning frequency the same or lower and allows you to use a smaller or same size box with varying results well within tolerances. Adding an external 12db/octave filter with a q=2 to a vented box whose resonance (fb) has been lowered can extend tend the bass response and produce a 36 db/octave cutoff, in some instances by as much as 12Hz - this applies to the same size box.
