This is going to be the official build thread for my pair of ported subwoofers featuring the Dayton Audio RSS460HO-4 driver. This is their reference line 18" High Output driver.\n\nThe box parameters I will be using were conceived by forum member "TLS Guy". Attached is the PDF file he created with BassBox software.\n\nI will be building the box out of primarily 1" MDF. I will state right from the get go that MDF is not my material of choice because I just plain hate working with the stuff and you have to be very careful not to damage it when installing fasteners or damaging the edges. But... Price is a factor and something like the baltic birch I wanted to use was simply WAY out of the budget.\n\nI have spent several hours designing the box using sketchup software to model the construction. Get my measurements and calculate volume and the final product I have decided on features what I consider to be pretty heavy duty construction. My target box volume internal per the design is 7.672 cubic feet and the calculated volume my design comes out to is 7.678 cubic feet. The only thing I was unable to calculate is the material that will be taken off by putting a roundover on all of the holes in the bracing. This will give me some more volume in the box obviously but I think it will be minimal and I expect it will be evened out with me putting in some Roxul Rockboard 60 on some of the internal surfaces.\n\nSo.. Lets get to it.\n\nThe following drawings and specifications are a DRAFT at this point. Once I have completed this project I will post accurate and detailed specifications.
