Hi has anybody simulated in winisd the GRS 15SSW-4HE on a 3cft box?  i’m a newbie and never build a diy box. this with room gain for  a 14×16 being 16 ft the longest so it would start at about 34.17 hz.  i was evaluating this sub sense i live in Puerto Rico and S&H for subs escalate with weight and price.

any pros or cons on this driver?
