i was wondering on your guys opion on this ... like the title says is 2 15" custom made subs too small for 4 ' cubed? the box is built already and desinged for 1 15" tuned to 34hz. but i was thing i might be able to retro fit it for 2 15". by cutting anouther subwoofernext to the other and possibly take out the port wall and seal up the box. or leave the port wall so it would be 2 15" in 4ft3 which sounds unrealistic to me but im not a expert. so bottom line is ... leave the box for 1 15" alone and buy/build a box for 2 15"? or 2 15s with ported or 2 15s sealed ....just wondering your opions thanks
