| If your box, as your sig states, is indeed 10cu.ft sealed you may wish to try them in a smaller enclosure for more accurate response. 5 cubes per 15" may work great for output but at the cost of accuracy. Try taking the subs out of the enclosure and then putting a bunch of books or similar in there to take away some of the airspace and then see how you like the sound. Try around 3.0net per and see if you like the change and then play with the space some more to fine tune.
