i was looking at at a bullet style straight through 30" long to put in middle, the ones that come on the 2.5" s/s systems are 26" long and straight through . so all you can do is add length.
the thing that hase the biggest efect is the back box with a large volume of sound deadening material and then with a mid box will give the most sound reduction. unless you want to get in to resenators and complicated maths but thay mostley deal with drone.
somthing to note is that the sound deadening material dose settle and get broken up by the sounde waves and vibration
