the rta is what i used, but it doesn't help me understand what slopes would benefit me where. i currently run all 3 pairs at 30 db/octave, and i got a pretty decent curve (A and C). but i just don't fully comprehend how the different slopes will allow the drivers to better blend with eachother.

yea unfortunately its a kind of experimental thing that you can theorize on paper but in car listening will yield the best results....get a quality test disc autosound 2000 or similar maybe iasca test disc and if you can an rta and that will help you to determine for example, if you want to run like 12 or 18 db per octave slopes on your midbass to get a quicker rolloff where the mids come in............

it'll vary with every system and car.
need to know exactly what you're using, where it's positioned, how much power each driver is getting, the type of vehicle, etc.. otherwise, no way to give a signle simple blanket answer.

yeah, i know slopes and what the difference is between them. just not the affect they have in practical tuning applications (particularly mine). e.g., helping the 3" meet optimally with the 6.5 based on their location. what aspects of the vocals would be different as a result of these different arrangements? so in gist, i understand xo's. i just lack the experience in tuning, manipulating the slopes to achieve "x" result.

Right, so i'm getting this tuning thing down and practicing eq techniques. but now i'm wondering if someone can elaborate on the different slopes and how they affect performance in practice. any real life examples would likely help. if a set for comparison need be suggested, you could use a 6.3 Iridium set in a '99 expedition for the scenario :bigwink:
