Klipsch Forte IIIs vs. Heresy III with a sub


I have Forte IIIs but wifey thinks they are too big for our living room / 2 channel listening room.  Considering swapping for Heresy IIIs and adding a sub.  I like to get the really low frequency in stuff like Sylvan Esso but also want the sound of Klipsch for classic rock and jazz.

Three questions:

Will the Heresy IIIs sound as good as the Forte IIIs do now if I add the sub?
Will I be able to cross the sub over to match well with the Heresy's bass range?
Will a Sunfire 8" XTEQ sub work well with the Heresy IIIs?

thanks...

Update...

Well with the help of my two college age kids I was able to convince my wife that two Fortes is better than two Heresys + two subwoofers. Along with that I listened to some Chainsmokers and Sylvan Esso last night when nobody was home to distract me and have decided I have enough subsonic bass to live with....at least for the time being. So the Forte IIIs stay! They truly are wonderful sounding and well built speakers. Now to add the MC2105 and see if everything improves!

 

Thanks to all of you for your advice and insight. I look forward to many years as a happy Klipsch owner now.


What? You ignored my advice? Wow man...and using your college kids to pressure your wife isn't even legal in most places. Unfortunately, you likely will enjoy your Forte IIIs for many years regardless of your crass self centered attitude clearly calculated to make Heresy owners feel bad. You have to live with that...however, get a Dennis Had Firebottle amp and I'll try and get over the Forte III issue...not going to be easy...*sniff*...
Wolf,
The drivers in the Forte III and Heresy seem to be similar, at least I think. Would the wider spacing of the drivers along with the larger front baffle of the Forte be some of the cause of the lack of coherency you hear between the two? I'm just curious...
I like tighter and more controllable bass which might be why I formed that opinion from an initial listen, plus I already had the subs subs that are very adjustable. The "new" mid horn has been accepted by Klipsch freaks as an improvement and I did like the general clarity of 'em, but the Heresy IIIs sounded more like the speakers I was using I suppose...those are Silverline Preludes I only replaced as I wanted the 99db efficiency for my little SEP amp. I still have the Preludes as I can't bring myself to sell them...yet...
