Seriously? Someone told you that?
Also, i am not sure if you are aware that the front is going to be a little bit more work than a standard box, assuming you are going to make a slot port on the front of the box. I just got done making a box for a 9515, where my height was only 16" high in the front, i had to make the front baffle one complete piece even around the port, had i not done that there would not have been any support or anything left where the sub cut out whole was, which is about 14" for the sub cut out. It can be done tho, mine turned out fine. Here are some pics of it.
Hopefully you can see what i am saying. The front piece is one piece, it was cut out around the port.
I am unsure of what you want to tune it to. As far as i know DD's are made to be tuned in the higher range of most subs, like around 40 or so, but i hear of people tuning quite lower with no problems. I tuned my 9515 to 37hz and i think thats a good frequency IMO.
