Small Speakers For A Large Room...


I'm about to move my system into a much larger room - ~4,000 cu feet - but for domestic tranquility (I love my wife far more than my music) will need to keep the speakers on the small side. What options are out there in a large stand mount or slender floor standing speaker that work well in large room? I don't listen very loud, and will have a separate powered subwoofer, but mains that visually dominate the room are not an option for me.

If you know of small-ish speakers that sound large, I'd appreciate some suggestions!

Budget?
Amplifier?
w/o those it's far to be specific. OTOH, you will find that many speaker makers have dealt w similar concerns AND the laws of physics by making floorstanders narrower and deeper than they used to. Think Wilson, Von Schweikert, Raidho, Vandersteen Treo, 5, 7, Sonus Faber, Horning, etc. If you are using a sub, you can go smaller than a traditional full range, anyways.
@ swamp... thanks so much for the suggestions. to your questions, amps will be purchased based on the speaker i end up with. since i'm starting from scratch with this one, i'm starting with the speakers and working back to the amp. budget is up to $7k new or used.
Don't know if 4' is too tall for you, but Zu might still have available the Definition 3 right in your price range. Very efficient, will fill a large room no problem, and only takes up one square foot of floor space. Has built in subs so no need for a 3rd box. And, come with a 60 day return policy if you don't like them.
PSB Synchrony One will fill that room, and they are pretty narrow floorstanders.
