[QUOTE="DejaWiz, post: 2960730, member: 569941"] Yes, I know it slopes, but why have the slope start well before it should? At -18dB/Oct slope for both the sub and mid channels, why do this.... Sub: 63Hz = 0dB 80Hz = -11dB 126Hz = -18dB 252Hz = -36dB Mid: 80Hz = 0dB 40Hz = -18dB 20Hz = -36dB When you can do this..... Sub: 80Hz = 0dB 160Hz = -18dB 320Hz = -36dB Mid: 80Hz = 0dB 40Hz = -18dB 20Hz = -36dB It's not going to be that exact since the slope starts a little before the set frequency, but I hope you get the picture. Set the sub LP to 80Hz and the BP-HP to 80Hz. That will (roughly) make it so there is only about -3dB at about 80Hz instead of -6dB at about 70Hz. [/QUOTE]
