I have 15" sub in a 4th order bandpass, but want to switch to a more powerful sub in the same box. Here are the spec. on the two subs.

Current sub
Qts 0.39
Qes 0.42
Fs 24.2
Vas 3.87
rms power/max 800/1600
Xmax 12

New sub
Qts 0.45
Qes 0.49
Fs 23.6
Vas 4.33
rms power/max 1000/4000
Xmax 25.4

What new sub are you looking at specifically. Vas is quite a bit higher on the new sub.. Give us your actual box specs and I'm sure we can recommend a good replacement for you.. Just off the top of my head DC level 3's and AA Chaos both do well in 4th orders, as well as a sundown X
