4th order build for 2 15" tc-3000s

with a 4th order there are 2 peaks
first peak is low due to the sealed side.

second peak is high due to the ported side.
Bingo. When you look at the graph of a bandpass system (or a bandpass filter in a crossover circuit for that matter, albeit a different topic), it's going to resemble a plateau. The first is around the tuning of the ported, the second is due to the sealed enclosure. Very difficult to get right, but I'd trust 80 any day of the week for a design.

 
Didnt get any progress yesterday, my buddy came into town, but i have all day today to work on it. Hopefully i can get it done.

 
Well got bout 90% of the box done today. Took a lil more time than i planned and painted more than i thought. I dont have my camera here but im going to try and get pics somehow.

I’m going to stick with the 4th order bandpass for now and see if it can improve it. The bandpass actually plays 100 rebased songs good.

I'd try rear facing. Have you tried opening the trunk to see if that restores your bass?
