Klipsch did a great job on this speaker.   Haven't spent a lot of time with them,  but they sound awesome . 
I'm hoping we hear more from Forte IV owners, these could be a great option for me with my low-watt amp.
I received mine last Friday. Like oddiofyl says, they do sound great. Midrange feels better than Forte IIIs. With the IIIs I felt really came to life after some 300 hours of playing. I don’t have that much play time on the IVs yet. It feels like they may be less efficient than the IIIs but I have no way of proving that. The black ash with salt and pepper grills looks great.
Congrats to all the new Forte IV owners. I have been enjoying Cornwall IVs for seven months now and am extremely happy. I imagine the new Forte is excellent as well.

Thanks Ozzy.... I really am curious what the reviews say.  I heard the C IV and H IV and bought the Forte IV sight unseen after hearing it was voiced like its big Brother.
