Default Either brilliant idea, or exceedingly ignorant.

Hi all. Please indulge me here. Is it possible to front horn load an already ported enclosure? In theory the port comes out in phase with the front in any properly designed box and greatly increases efficiency at fs. Why can not the whole kaboodle (driver front wave plus rear wave from port then be combined and fed into a folded horn? Would this not render an extremely efficient design?

Not talking about bandpass, but a Klipsch style folded exponential horn coupled to the driver plus the port?

Here is sort of what I am speaking of but mentally put the port back into the same motor board as the driver. http://www.rockprojekt.de/Technik/Im...ded%20Horn.gif

I'm apparently extremely ignorable. I can however continue this conversion with my self until I solve it. Now I am wondering is not having the driver in a sealed enclosure prohibits its action as a pseudo compression driver, thus limiting its potential SPL in trade for extended LF?

Have patience. It's only three hours since you asked the question.

LOL sorry I can't add anything to the discussion as I have zero knowledge about horn loading, but I thought I'd chime in and say hi

Give it a few more hours it is probably a bit early yet for a lot of the membership!

Thanks , hangin in. I have seen variations on this so I know its not completely without merit. I always wondered why PWK did not vent the drivers right into the horn instead of sealing them. The K-33 for example works about as well used either way. There must be a phase or comb filtering dynamic that I am missing here, though it seems to me to be a no brainer best of both worlds possibility.
