Real nice SExxx, this kid is 18 years old and probably saved up for these subs or got them as a gift and you immediately tell him that his subs sound terrible. He wanted to know how big his slot ports should be, not whether or not we thought he had a good sounding quality product.
Which excursion subs are they the natural excursion(crap), the Ultra excursion(good spl/decent SQ) or the Flame excursion( POS ) or more precisely the Natural Excursion (AW122T), the Flame Excursion(AW121T), or the Ultra excursion(AW1205Q)??? You should also be able to go to their website http://www.audiobahninc.com go to the product and support section and download the manual and some box specs there granted their box specs usually arent that great.
