I was thinking about putting them in a Sealed box now there recommended in a .7 - 1.0 Cubic foot Box. How would it sound in a 2.00 cubic foot box?? or should i just get 2 single 12" 1.00 Cubic foot Boxes and drill them together?..now if i were to drill holes in the box to pass the wires through will that cause problems with sound if i were to seal the holes with silicone?
