Well, in general, at lowish frequencies, the NFB factor divides the size of the open loop output resistance at the point the NFB is taken from.
Eg: 15dB of NFB is about a factor of 6. If the OL output resistance at the point the feedback is taken from is 6 ohms then after applying 15dB of NFB you would expect the output resistance to be 1 ohm.

Which is why I said in an earlier post that you can't directly go from NFB to DF, yet the OP still seems to be asking for this.

What is the definition of an X ohm output on a OT?
When an OT has a e.g. 4 and 8 ohm output what makes the 8 ohm output an 8 ohm output? .....the DC resistance is much less than 8 ohm I assume. Is it measued at a specific frequency?

bassreflex is "standard" these days, but it is more or less distortion + headache inducing technology.
thankfully ear is not sensitive to distortion at bass

open baffle people may agree that their stuff is cleaner and better
