Transmission line speakers!

A number of years ago I had a pair of PMC's FB1I, used in a small bedroom driven by a Bryston B-100. I remember them as being well built and very good sounding speaker. 

mrdecibel,

I don't think we can agree to disagree in this case. The transmission line is the opposite; it amplifies the rear output of the bass driver, and the folded horn of the Khorn amplifies the forward output of the bass driver. 

Roxy, do you understand that our ears are mini speakers, playing a role in reverse. Does not matter if the output is from the front.or the rear of the driver, imo. A mic is a mini speaker l8ke our ears in reverse.

Btw, I am a fan of isobaric loading, which is another way to do bass.

It's not a matter of opinion, they are different by definition, and what they do.
