f6 bandwidth defined?

I'm not sure if this is what you're asking, but in general I think you can factor in the following:
A vented enclosure acts as a 4th order HP accoustic filter (24dB), add a rumble filter for an additional 2nd order HP (12dB) & you have a 36dB slope which is rather substantial when compared to the more gradual 2nd order HP properties of a sealed box. Comparing the two would show the vented box having a much narrower bandwidth due the faster rate of roll off.

Thanks for the reply...i should clarify. I'm wondering whether it (F6 or -6dB point) is measured from Fb or the highest peak in the frequency response....our brains and nervous systems constitute a belief-generating machine, a system that evolved to assure not truth, logic, and reason, but survival...

Originally posted by speakerguyI always thought it was defined relative to the nominal passband sensitivity.
Why, are you looking at a design with a large hump at the knee like with a super boom box alignment with a Q >1.2?
