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.  

They redesigned other things with this speaker including the drivers and crossovers, and that interests me...the rear port doesn't interest me so much because I prefer having the sealed box "accurate bass to its limits" with my Heresy IIIs, and easily blend in the REL subs I use...I like the control I get with the subs. I'll listen to the IVs at some time but for now the IIIs are simply great sounding things that were a relative bargain at 1500 bucks new (and they're the "Capitol Records" version which is possibly meaningless but they make them at least "seem" special).

I have mentioned before, on other threads, that Klipsch has made the Heresy design, in pro models, for years, and all have been ported. This is nothing new for them. I believe the IV is a big upgrade, over the III. 

I would like to hear the IIIs and IVs side by side in an audition as that could be fun...I like my IIIs enough (including their lack of ports) to hang with 'em for a long time until IVs become less pricey, and since I just read a review of some also non-ported Magicos I feel even better about portlessness (I can turn off the rumble filter on my phono preamp, although I leave it on anyway to put less stress on my small single ended amp)...I like the AQ wire idea in the IVs and with redesigned crossovers and the like I bet they do sound great. "Upgrades" certainly but the degree of detail and coherence in my IIIs doesn't really beg for improvement...they beg to be listened to, and that I do...frequently.

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.
