Hi all, I've just ordered the BFD DSP1124P. It will be here sometime next week. I've just measure my sub's freq response. I need help on how to flatten out my freq resp as I'm totally new on BFD. I read/printed the BFD guide on snagbug site. Here is what I've got so far. This is for my diy Tempest corner loaded, xover at 80hz. All speakers turned off except the sub of course. Notice: The data are raw. I haven't add any corrections yet. I need you guys help on what freq and bandwidth should I filter at. I just want a head start I can't wait for the BFD to arrive. Thanks. Al, Edit: Correction: Look like the graph from bfd guide site auto apply the corrected values to the graph.
