This is the woofer suggested for the tuba if you want more @20Hz in the tubsa.
This is the sub that is suggested for the Joseph Crow sub we are building. The sub requires 2 of them per sub, and 2 cabinets will be used(which is the same one suggested for the Tuba, but they said if you want to go deeper buy the one I did for the Tuba...so I did.
Here is the info on the Joseph Crowe subs I am building.
Recommended amp.
The amp is a 4ohm amp.
Now here it talks about different ways to wire the coils for different impedances.

Now what I am trying to find out is if the 2nd (tuba woofer) to last sub is going to work in the Joseph Crowe sub ok. I do not understand how to compare the woofers to know. All I did see was the Tuba sub appears to have more SPL @ 20hz when the dual voice coils are wired in Parallel. The problem is when wired in Parallel the impedance is just under 1ohm! Now if I understand correctly...I can then wire both subs together in Series and the impedance will go to 2ohms. Now the Joseph Crow woofer @20Hz is 76.6db @1meter/1 watt.
The Tuba woofer is coils are wired in Series it is pretty much the same, but when when the voice coils are wired in Parallel it is 82db.
I am assuming that when you add a 2nd woofer the efficiency goes up 3db, but I see adding a 2nd sub is 6db, and then you have the room gain which I have heard could be as much as 9db with a single subwoofer.
Will the Tuba woofer perform as well as the Crowe woofer if the Tuba woofer is corner loaded and the crowe woofer is not?

A Look at Series and Parallel Subwoofer Wiring
Does the way your subwoofers are wired affect how they sound? We look at series and parallel woofer wiring in detail.
