Well on saturday I finally mounted the drivers in their baffle. i went ahead and stuck on some music and began to listen. now Everything you have ever heard about IB bass is 110% true!!!!!!!!!! I literally sat there for about 3 hours listening to different music and movies. There was such a depth, clearity and effortlessness to everything that I kept getting chills in my spine. Let it be known that I am now a converted IB believer and I will never have any boxed sub in my system again. I am going to get everything cleaned up tonight and get some pics up. Now on to some questions................. I got my first measurements last night. Here is a graph of the correted numbers I got from a Rat Shack meter.... as you can see I have some problems haha! I have two dips at 18hz and 45hz. Below 18hz the response actually climbs again. I was still hitting over 85db at 10hz. I thought I would start out with bringing that big hump between 25 and 35hz down then boosting the dip around 45hz. the one that I am concerned about is that dip at 18hz. I am afraid to really put any boost on that. What do you guys think and does anyone have any suggestions? Thanks a ton!!
