[QUOTE="Jepalan, post: 8404654, member: 655519"] Just like TylorFade said, most passives use -12db or even -6db slopes. The midbass to tweeter cross point will be electrically matched (so, essentially same freq for HPF & LPF with consideration for filter type). OP - if you are hearing a difference active with the crossover points matched, it is probably a level matching issue, not a x-over frequency issue unless you have some really weird acoustic null or peak going on. What do you mean you have "beaming issues"? Beaming means you would be losing high frequencies from the midbass when off-axis. It doesn't make sense that you would LPF the midbass lower to treat beaming because you would lose even more HF energy. [/QUOTE]
