Heresy IV vs Zu DW6/Soul mk2

I have listened to ZU speakers at audio shows and always felt they were a bit bright and in your face.  The Klipsch series IV speakers are their newest and really sound wonderful.   I’m still looking for a used pair of Cornwalls series IV for a decent price. 

I’ll toss my vote in for the Zu’s too.  I have a SET 300B that I use with my Zu Soul Supremes.   I listen to a ton of live Dead (Dave’s & Dick’s Picks and all the box sets).  The Zu’s throw a great soundstage (and aren’t bright).  I couldn’t be happier but I would love to try the Volti Razz in my room, but I really don’t see it happening. 

I’ve been living happily with the Zu SS’s for about 6-7 years.  I’ve used different amps, First Watt F8 and SIT3.  Depending on your amp you might want to get the impedance wrangling resistors to make them look like 8 ohms to your amp. 
 

Enjoy!

I can't speak for the Zu, but I have the Heresy IV and have not found them to be fatiguing at all.  It's hard for me to think how another speaker, other than another Klipsch Heritage like the Forte IV, could sound better for live presentation.  

Also consider the following: the Heresy maintain a dynamism and "live feel" even at LOW listening levels, and moderate levels...  That's one thing that really impresses me about them; I usually listen at low-ish levels and I'm continually taken aback by how fresh and impactful they sound.

That said, are they my "lifetime" speakers after a lifetime of listening through the "linear sound" of Epi 100s...?  Maybe not, and I'm going to give the Q Acoustics Concept 50 a try, see what I like better as my "forever" speaker... but I do not regret my Heresy purchase and they have really brought a lot of engagement and they are addictive such that I might not be able to let them go and could see "rotating" them in from for part of each year just to freshen things up a bit, even if I do ultimately settle on the Concept 50 as my primary.

I don’t want anyone to get me wrong. The Klipsch series are great speakers. The whole line up has something for everyone. There is something to be said for a historic company, having produced iconic speakers for so many years. I did like the sound of the Heresy’s. Dynamic, the complete opposite of boring. Great mid, nice open sound stage. And they were particularly good listening at low levels. Someone I talked to told me I didn’t give them enough time to really settle in, and maybe they are right.

I don’t think you would be at all disappointed bringing them home. 
 

A speaker that has peaked my curiosity is the Heretic line out of Montreal. High sensitivity. The Big coax, big box, series crossover. All those combined, should make for a dynamic presentation with a soundstage to match.

I own Cornwalls, and really like them! They’ve been heavily modded w Crites tweeters , crossovers and major internal bracing. I’m regularly amazed at how delicate these big boxes can sound. And of course, they can crank it out. Been wanting to pu a used pair of Heresy’s for fun so I can do some comparisons between the Klipschs. 
 

Sometimes, you just need a big box with big drivers.
