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...

Show your wife pictures of some other larger speakers and she will change her mind. Enjoy ! MrD.
@mrdecible - I was going to say: Borrow some La Scallas for a week. They will make the Forte's seem tiny!
dweller, that is another way to do it, but imo, might confuse the op to what he would want, as there are some design differences. Just a few, lol. Enjoy ! MrD.
The Batphone just rang...clearly I relish any opportunity to blather about Heresy IIIs...I listened to the new version Fortes at around the same time I was auditioning the Heresy IIIs, and although the Fortes are a somewhat unique design they do sound similar to the Heresy IIIs, but for my tastes anyway, not quite as coherent overall. Also the size of the Heresy is more appealing to me so when I found an "open box" deal on Ebay I snapped 'em up...1000 bucks off list price (surprisingly it was the "Capitol" version that arrived, although this version is sonically identical to the regular version for 500 bucks more, these come with unique finishes...black is sort of dark purple). You can still get that deal by the way...some company based in Nevada called "acousticsounddesign." Free shipping to my house near Boston took 3 days! The price difference is such that you can buy a great sub and the Heresy's for less than a Forte pair...I already had 2 REL subs, and those combined with the Heresy IIIs 58hz low frequency limits sound astonishingly good. The short and fat stature of the Heresy cabinet is somewhat unobtrusive relative to tower or standmount speakers I've owned so that's a good thing also. The 99db efficiency and 8 ohm rating fits with my little single ended amp perfectly. Here's a cool review: https://www.stereophile.com/content/listening-119-ken-micallef-june-2018
