Best standmounts with a 7" woofer/driver

I would like a bookshelf that can move some air. Big sound. I currently own Revival Atalante 3.They have a nice 7 inch driver. Just shopping for possible upgrades. My room is 14' X 12'

Not sure what specific upgrades you're looking for. If you're after more air movement, a bigger sound, or deeper bass, the Atalante 5 could be the best candidate, while still retaining the traits you like in the 3. The options might be limitless and people are shooting random darts here unless you specify what you're aiming for.

@big_greg  Thank you for bringing this to our attention. After reviewing its specs, it is realized that the xDB model actually 'cheats' a bit and may not be classified as a traditional stand-mount speaker since the entire 'stand' functions as an extension of the transmission-line like bass port. Its sibling, the Studio II, is more in line with what we're discussing here—a sealed box design with an 8" long-excursion woofer reaching down to 28Hz (?dB) moves a lot of air.  There’s a connector inside the binding post panel that can even be disconnected to reduce the bass response by 2-3 dB if the room is overly pressurized.  Interesting.
