No worries!
This kinda depends on what you goals are, and how big the room is. For my money, the whatmough is out because it’s sealed, and it’s a 10”. AND I’ve never heard of them(wtf kinda name is that anyway lol)
The Klipsch is rated at 29hz and the WM is rated to 22hz. The problem is that the WM will also start rolling of at roughly the same(probably 35ish). It will have a shallower roll off slope, but due to its size, it won’t matter since it will go deeper, but at MUCH less output. For example if we had a competent sealed and ported version side by side, the ported sub would have as much as four times the output by 20hz. That means you’d need four sealed to keep up. These two are apples and oranges though so…
If these are the only two options, I’d buy two of the Klipsch. You’d be able to possibly get a much flatter FR, more output and likely better sound overall. No. I don’t believe the WM spec sheet offers anything amazing. Sorry mate.
