Klipsch Heresy IV

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.

The H4’s have a tractrix mid range horn, the woofer is the same as the H3. I have H3’s but would like to hear the H4’s but will be keeping the 3’s. 

I'm scratching my head about the price increase.

The cabinet size is obviously important when a speaker is ported, as you're just not going to simply stick a port in there without considering everything...including what the "new" 12" bass driver's design might be. Roy Delgado did a great job with the other new "Heritage" re-designs and it's reasonable to assume a lot of time was spent considering how to get another 10db of bass from the Heresy IV as the lack of low bass is a common criticism of them. Duke's or anyone else's opinion isn't as valid as what the individual listener thinks of the sound of the IV with the complete redesign, and thus ends my statement of the obvious.
