Need help in sub box sizing

[duckmanjbr]

It's been a while but I did this professionally a few years back. CW subs generally have always taken a little bigger box mainly because of not being as efficient. As already said, sealed boxes are always a little smaller and there a some tricks you can use to make the sub think the sealed box is bigger than it really is. The Ported boxes are generally larger and tuned to an exact frequency. I personally have always liked the sound and range of a sealed box myself. It really comes down to more design than just a box. A sealed box can be smaller, can use more power and likes that extra power to get better performance, and is much easier to get custom and hide in some unusually areas. The ported box and the 4th order boxes are designed to increase volume at lower power levels. They tune the box to a frequency and increase volume output at that frequency by as much as 6db. As I've said I personally like the sound of a sealed box w/ lots of power. I like rock and top 40 music and don't really get into to much rap so the sealed box gives much better performance over the large range of different music. If you like more rap or bass heavy music you might be better off w/ a ported or an even heavier 4th order box! The box will always turn out better if you design the box around the car first and the sound you're looking for second. Getting the most out of a sub box can be due to a lot of details so simple box design alone is never enough!
