What are the advantages of a rear loaded horn enclosure over a regular ported box?

I did for the 8"s.

I'm curious as well. good post

This is what Pete at PWK said:

None. Just like there are no advantages of a bass-reflex (ported) box over a rear-loaded horn. Depending on the enclosure’s surrounding environment, woofer parameters, target response, and target listening point, one alignment may perform better than the other. And those just two options. Again, depending on the above stated variables, a transmission line may outperform both bass-reflex and a rear loading horn. Perhaps a 4th, 6th, or 8th order bandpass, perhaps a tapped transmission line, front-loading horn, tapped horn, aperiodic bass-reflex, Voigt pipe, etc…

Higher efficiency across a greater portion of the audio spectrum. Instead of being tuned to a single frequency, horn-loaded enclosures are essentially tuned to every frequency before the drop-off point. Very desirable in SR applications.

They also typically can't get as low as a ported box given limited space.

But you could design it to hit as low?

You can achieve a flatter freq. response, greater cone control/mechanical power handling, and more output over a certain range. Very efficient boxes. They play lows, but don't have the bloated low end most people like. The tonal quality can be great though.

This is given they are designed properly in the right application.

Is it just me, or does that make no sense?

Ya, that made no sense to me either. I have no idea where he is coming from nor what he is trying to tell me.
