Klipsch Heresy iv...Your experience.

I already had the IIIs, and was simply so curious about the IVs after the positive reviews that I just had to grab a pair. I noted someplace else that the IVs are far more sophisticated in their assembly, and compared to my IIIs, the finish is much better. My IIIs are the "Capitol Records 75th Anniversary" edition with an "ebony" sort of deep purple very thin (scrapes off easily) finish over some veneer. So...The IVs initially did what they’re supposed to do, deeper bass, new midrange tone. But there’s the rub...the mid horn on the 2006 designed IIIs is a far more complex (weird design with a the titanium driver blowing into a long pointy tube with 4 holes in the base where the diaphragm connects, but hey...it works) design with a titanium driver, and the poly driver horn on the IVs is a far simpler and shallower "bolted to the flare" design with a small phase plug...the mids on the IVs weren’t making me smile...even after a couple of months of break-in, certain tones (especially acoustic piano) on recordings I’m very familiar with sort of barked...upper mids. An acceptable sound if used with somebody else’s gear maybe, but I demand that speakers I live with make me instantly satisfied at all times or they’re outta here...the IVs are beautiful, well made speakers that just didn’t work for my ears, and they looked so good I figured a quick sale would ensue...it did (I priced them fairly though, and figured my small loss was an "extended audition fee.") The new owner seems to like ’em. My IIIs are likely to stick around, but I’m now curious about ZU stuff and a pair of Omen 2 "dirty weekends" will be in my room by Friday...it’s a risk of 100 bucks for a 2 month audition...what could go wrong?

I'm going to post my negative opinion about the iv's. I do see that everyone posting here seems to have really positive things to say. Pro is the high sensitivity so you don't really need a beefy amp (although it couldn't hurt). I did like the natural sound they provided. They are highy dynamic. Cons however made me return them. They take up a lot of room in terms of width. I didn't like the floor and tilt up sound. I prefer the tweeter ear level. The midrange was a bit leaner than what I prefer (I may just prefer more warmth in general). The bass was good but I wouldn't call it tight. Ultimately I wound up returning them. Most people that love them seem to comment that they are like listening to live music and so some of the "flaws" are acceptable. Ie if you criticize it on all the details you are missing the point. They are just meant to play. Hope this helps...

New Heresy IV review

The ZU Omen 2 "Dirty Weekend" speakers, at least compared to the Heresy IIIs I've owned for years, had a sort of midrange "veil" or lack of what I seem to need in ultimate clarity. I even swapped in a good MOSFET amp (to compare to my trusty tubed single ended pentode Dennis Had "Firebottle") I have for a second pair of deck specific speakers and had the same issues, so back went the ZUs...note ZU was great to work with...nice guys. My issues with the IVs could have been specific to that pair although unlikely, so my theory regarding the perhaps "better for me" last generation titanium mid horns still stands. I might be the only one who feels that way, but I do get some satisfaction from the fact that I now am even more happy with the IIIs.

Fair criticism of the Omen DW's... clarity is not their strong suit.  You have to go up the Zu line to get better clarity and resolution.
