Trying to clean out some stuff from the house/office. Selling a single 10", Slot ported box (Box only, no sub, professionally built by Progressive Auto Sounds). It's made from 3/4" MDF and has a recessed mount for your sub (flush look),and was designed/built for a RE SR10, dual 4 Ohm speaker. The dimension of the box are 11 3/4" x 12 3/4" x 30". The box is in pretty good shape and cost about $200 to be made. $25.

 

Cubic feet? Pretty much sold if not gone yet depending on cubic ft.

 

Sorry, I'm not too sure what the internal volume is. I only know the external dimensions (as listed above). I did have an RE Audio SR10, dual 4 ohm sub in there before and that set up sounded awesome. PM'd you my cell #. LMK if you're still interested.
