Klipsch Heresy IV

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.

10 db of bass ?....= 10 hz of bass. Guys ( and gals ). You need to look at some of the pro versions of the Heresy’s..........again, nothing new with the ported design, except for the port itself. R.D. had much to do with the design of the pro models. Amazingly, what needs to be done to the news ones, as well, is a " heavy layer " of Dynamat on all of these horn drivers. Danny Richie, on the mods of the Forte IIIs, did not do justice to the mid horns. A recent Steve G. video, about a fellow modding a Cambridge CXC transport, stated, that with every mod that he did, the Dynamat made the most significant difference, in SQ. Again, I’ve been using Dynamat ( and some roofing repair tape found at Lowes and THD ), for the longest time, on not only horns, speaker frames and cabinets, but on electronics, of every kind. This fellow, also recommends, to put a book on top of the chassis, something I have been advocating, for the longest time. I know, this mod stuff belongs on another thread, but I am bringing it up here, because it is a cheap, but very relevant upgrade. I know of only one person, who applied Dynamat to his horns, who did not find it superior in sq, and I do not, for the life of me, understand why. Enjoy ! MrD.
