I built a ported box for the JL Audio 8w7 out of 3/4" MDF to the specifications listed by JL Audio. With my current setup, two of the boxes would be too wide to fit the wheel chair in the middle, so I have no use for it. I'm now making a fiberglass fitted box so I'll be keeping the sub. I also have all the pieces cut for a second box but never assembled it. I can give away those as well. it is uncarpeted and if your'e going to paint instead will need some filling and sanding as the screw holes weren't filled and some corners may have 1/8" overhang or so.

I'm in St. Mary's but drive up to the DC area every week or two.

Box is 25.5 in. x 10 in. x 12 in

 

you get rid of it yet?

 

No, not in the five minutes since it was posted It's nothing special and only ate about $30 of materials, so not really worth it to sell, just trying to help someone else out if they have or are looking to get the 8w7 subs. I did trial fit it in the xB and it sounds phenominal, much better than the sealed box I previously had, though that one was smaller than reccommended.
