Jughead, I can tell you from experience that the Breeze are awesome. Mine have a ton of upgrades and flat out kick butt. I have a similar sized room and the Vapors really fill it with beautiful sound.
Having said that, I too have heard the Auroras and they are big, bad and have a huge presence (in a good way). Sounded wonderful with anything and can really rock.
If it was me, I might do one of two things. The first option would be to have a killer pair of Cirrus built with the larger Raal tweeter. These could truly be end game speakers and you would be very, very happy. BUT, if you ever wanted more down the road, you would have the option of upgrading them to Joules by adding the transmission line cabinets and having Ryan change crossovers etc. Nice option to have in your back pocket!
Or, you could have Ryan build a killer pair of Breeze based Joules in your budget and have it all right now.
Lot's of options but the best way to proceed is to call Ryan, go over your budget, tastes and room and he will give you great choices. He is a detail freak and you will have a bespoke pair of uniquely custom speakers with end game sound.
