i think when we buy any subw,we also get some sort of advice of recommended box,whether sealed or ported.We just cant make any subw box without any parameters/guidelines.
e.g. i bought my subw from crutchfield.These guys do give advice abt dimensions/volume of box whether sealed or ported.They also recommedn different boxes for different types of cars like seadn/hatchback.
I got my box built by local guy using crutchfield advice. |
