I for one think you'll be very happy with your choice. Then again, I'm a 20-39 cylinder owner

. Having a friend with a box, though, my experience has been that both form factors offer equivalent performance - in equivalent configurations. SVS' position has traditionally been that the lower cost of design and construction of the cylinder allows them to offer slightly more peformance at a lower price point
vis-vis the Boxen. My experience seems to bear that out.
Oh and by the way, if you haven't seen one in person, they're bigger than you think.
Congrats, have fun, and enjoy!
