I was going through my post and found that I sounded arrogant here. Certainly not intended to sound that way. Thank you for the advise Joshua! :thumbsup:
Sorry I somehow missed this. Captain, it would be 5mm on all the inner walls excluding the front, right? I think it would be close to 11% down considering the bracing scheme that is suggested and the volume of the port. But this is all moot now.
still feel something is wrong. It won't be that big difference. Regarding double stacking front and back, nothing can be said for rear panel double stacking. I found it make heavy box still stable and less resonating compared to my other boxes.
I too feel so. Of course stating from the face value of the dimensions of speakers and the bitumen sheet. Anyways, since I'm looking at pure bitumen sheets, it is moot in more ways than one.
