Modern subs have digital electronic crossovers that add approximately 10 mSec of delay by themselves.
The rest of the delay is simply due to the acoustic response of the sub itself.
This delay is relative to the electronic signal that drives them.
You are correct in that like for like a big sealed woofer in a floorstanding speaker would have the same group delay as a sub that was designed identically.
However most subs are designed to go much lower in frequency than the woofers in a floorstander, so they generate more delay.
Make sense?
