I use an Eminence sigma pro in my setup and I like the bass response.
You can download the datasheet for it.

I'm trying to do the same thing with my OBs. I need high efficiency midbass fill and I want extreme tightness and tone. The only thing I could find that is over 100db in the midbass were a few 15" guitar speakers. I ordered the Jensen c15k to try. Meant for open back cabs, it should be just the ticket. If I'm completely wrong, I'm out $240. But that's not too bad to find out.
I must confess my favorite music is that made by the Rolls Royce Merlin.

You may have to use 2 of something or stick something inside a big@ss horn to do 100db at 50hz.

2x TD15s in 355l sealed 96db 1w/1m 101db 2.83v/1m f3 44.6 hz assuming 2pi space.

1x TD15m in 157l vented 97.64db 1w/1m 98.48db 2.83v/1m f3 42.59 hz assuming 2pi space

2x TD15m in 314l vented 100.65db 1w/1m 104.5db 2.83v/1m f3 42.59 hz assuming 2pi space

I would email or call John J at AE Speakers if you end up getting interested to find out what the lead times are.

Hard to find but wonderful, the BeezKneez. My alltime fave 15" driver 30Hz to 3k 101dB and gloriously fast due to the light cone and powerful motor.

Please remember that you won't find any 15" woofer that's 99 dB below baffle-step

Maybe better ask for the enclosure type first. A horn could be fine (e.g. La Scala) or a large OB, which would get around the baffle step.

Altec 515? In a largish enclosure they will pump out 50Hz without issues. Pretty fast, very detailed and revealing. In the wrong enclosure they sound bad...

I second the Altec or GPA 416 & 515. They seem to fit exactly what you want. They do need a big box.
Take the Speaker Voltage Test!
