ok so i have a box 17" deep 49" wide 23 1/2" tall tuned to 35hz with 4" port..... then i have a box/port on the face of that that is 4" wide (inside diameter).... the idea was to increase cone space with 3 15" subs and increase box space while still using only a 1000watt rms amp. but my question is how do i maintain my 35 hz tunning with the 4 inch port on the face? and wont i have a alot of canceling sense i have a ported box blowing into another port? anything helps thanks can send pics pm meView attachment 26530771View attachment 26530772View attachment 26530773
