Re: Behind the seat speaker box and questions

MDF is typically the wood of choice in speaker boxes as it is dense. As far as air space you should look to manufacturers recommendations or use a subwoofer box calculator. Using the Theil Small measurements you can calculate the results from the enclosure. One thing to note it is important that the box is totally sealed any air leakage to the front side will cancel output from the sub.
