Klipsch Heresy IV

Usually porting speakers, no matter what type, gives the illusion of more bass, but it never seems as tight or as "real". If you want the real story do some research on both types of speaker design. I think it was some Stereophile writer, probably Dudley, that wrote a short article about this recently and essentially got everything wrong. So read this article and go the opposite direction and you will be on the right track.  

What I cant figure is why Klipsch would increase the  cabinet size and add a port. Perhaps they put in a bigger woofer? No way the bass is as tight or as real and rear ports can be problematic. It would be nice to get Duke's opinion on these issues. I know hey said he liked the new horn geometry on some of the new Klipsch designs.

I think it is patently absurd to assume that any redesign will automatically sound better than its predecessor. 

My point was and is that ports require a smaller cabinet than sealed. Last time I looked simple laws of physics applied to all speaker companies even Klipsch. 

I liked the 8 ohm compatible statement on the website when addressing the impedance of the Heresy.
