[QUOTE="FoxPro5, post: 1590750, member: 562649"] Well you kind of have a few options. One would be to run the x-over points strictly from the HU like you are talking about, and then run the amps full range (ie not use them). Or you can run the HU "pass" on all frequencies and let the amps take care of it. The dissadvantage here is lack of adjustablility at your finger tips. If you do both you effectively double the slope. FOr example, if you LP the sub at 63hz at 12db/oct on the HU and 12db/oct on the amp, you now have a 24db/oct at 63hz. At least I think that's correct. Also remember that the slope is in db per octave....which means higher slopes cut the frequencies at a greater rate than shallower slopes. The best way it was descibed to me would be to imagine two people talking to one another. The end of their sentences would represent the x-over points and how fast they stoped taking would be representitive of the slope.
