Heresy IV vs Zu DW6/Soul mk2

I've had Heresy IIIs (Capitol Records version) for a few years and love the things. I tried a pair of IVs (figuring they would be better) and didn't like them at all although they're really well built...some upper mid frequency anomaly drove me nuts (the plastic midrange diaphragm on a re-designed horn is what I suspect is the culprit...the IIIs have a completely different titanium longer throat mid horn) so I sold them off. Same with ZU DWs...they sounded lame compared to the Heresy IIIs so back they went. The IIIs amaze me every day, and maybe just thrive on good gear in front...Schiit Freya preamp with an SEP tube or Pass XA 25 amp work perfectly in my rig. 

Forte IV has almost the same footprint as the Heresy, so if you can swing a few extra $$, I'd recommend them over the Heresy.  Sounded great w/175 wpc class AB amp and tube pre; even better w/30 wpc class A.  Don't let anybody sway you with the adage that "they're best w/low power tubes"; IMO not true at all.

For those interested in the Heresy 4's try some Dyna Mat damping on the mid and tweeter horns sections. They definitely help to smooth out the mid and upper ranges. Less "shouty".... more relaxed presentation, but still maintains the lively and dynamic presentation that the Klipsch's are known for.

Cheers.....

@fatdaddy2  +1  And with the Forte IV  there would be no sub needed which might help the OP as well.  But, those low-slung Heresy IV are really cool as decor, too... but then so are the Forte. 

I gave the dirty weekends a 60 day trial and returned them. But not for lack of bass. If you don't want your room to rock, I suggest you don't get them. I had to get footers to isolate the speakers to keep my room from rattling. I actually thought they lacked treble presence.  I know a fellow who loves the previous model for listening to '60s and '70s rock music. I never heard the Heresy's.
