Hi, how are you? The thing is that i have a little car and i need something compact, something easy to transport for rehealsals . I have one 12" speaker: http://www.mcmelectronics.com/product/55-3242 . it was damaged and someone repaired it for me. And mi brother sold his car and stored his slot port car subwoofer cab. So i was thinking in combining the cab and my speaker. I uploaded the dimensions of the cab. I was thinking of dampening with foam pads.
