So is this the same or similar as to what Emerald Physics is doing with their OB bass sections?

I am really digging this...
Winslow...Heat??? you mean from compression or dissipation from driver??

ah, so that's why I get hot when playing my bass

btw, a danish guy bulit a similar folded dipole, some years ago
but not with a full range driver
so his main issue may have been the midrange

That's not it.

Energy (work) is volume displacement times pressure.
Hi,

Oh dear dear ... pointless points ... how much does the air vary in your
neck of the woods ? and can you do anything about it ? tedious .......

rgds, sreten.

Your saying my fallacy is wrong ? Might be a joke, I'd get that.

I don't need to address "your" problem. Your wrong, and like many other
people who are, your missing the point that it is totally uninteresting.
Similarly you want your points addressed whilst making no attempt
whatsoever to address the counterpoints presented, which actually
are addressing the problem as stated, but not agreeing, so ignore.

Hi,

The thing has been built, obviously works, with high efficiency due to the
multiple bass drivers, and its easy to arrange effective force cancelling.

I'm not knocking it, I just find the description somewhat inaccurate.

6 drivers with the same impedance as 1 = + 7.8dB, but with 3 in series
wired in parallel with the other 3 that knocks it back to very near + 6dB.

rgds, sreten.

You are still not solving my physics problem.
