A box tuned like this will be a 1-note wonder though (not to be used for daily listening...just for SPL comps) that box is better...but you still wont have enough port area. you will need ~70sq inches of port area or you will get port noice.

marshall white Gold Member Username: Southernrebel Monroe, Louisiana USA Post Number: 2249 Registered: Mar-04	Posted on Wednesday, February 22, 2006 - 04:36 GMT a decent rule of thumb is 12-15sq inches of port per cuft of box. 100sq inches is plenty for nearly any pair of 15's in ~8cuft.
