I was just mostly wondering what people experiences are with eq'ing and blending multiple subs. I have a BP1503 sub in a ported enclosure tuned to 20hz. I just finished my prototype av12 sealed sub(1.1cubes) I call it a prototype cause Its still nekid and I wanted to make sure I liked it which I do. I only built one but have another on the way(driver is staring at me now) So I plan to have two sealed av12's, one to each main speaker of my room and then the BP1503. I want to use all of them. Then I got the idea of instead of building an LT circuit for each av12 I has just going to cross the ported sub around 50hz. Or If anyone could help me design a hipass at around 30-40hz to take over as the sealed rolls off. Then Would I eq both sealed and then the ported or all three at the same time. Not sure cause there are so many ways of doin' it. I was going to run the sealed of the main pre-outs and keep the ported for lfe but though I should just use them all on the lfe.
