Message me and Tell me how big you would like the box, what size of subwoofers, how many, an ported or sealed. Also what type of subwoofers you plan on using and i can look up the specs (theile smalls paramaters) of the sub but sometimes I cant build to best match the sub(s) because of space limitations so i will try and get the closest I can. I have a table saw, router table,miter, and a drill so i can do most boxes also I will not do fiberglass boxes or weird shapes. The sub boxes pictured are the ones i made for myself so i used particle board instead of MDF and did not carpet them to keep cost the down
