output and SQ question

[fasfocus00 5,000+ posts]

okay i've narrowed it down some but now i'm a little lost. I'm gonna run a single 15" in around 3.5-4 cubes tuned to around 33hz.

All things between the subes are pretty equal but let us assume they are all equal except for the following:

Sub A has an Xmax of 27mm and a sensitivity of 88db

Sub B has an Xmax of 24mm and a sensitivity of 90db

will these differences have any change in output or SQ? what's the differences?

As long as you're tuned that high, it's not going to matter either way.

You can derive absolutely nothing about the "SQ" of a subwoofer from those specs.
