I'm a little confused, although many will tell you the 22's combined with a sub are killer, why are you comparing the Infinity Beta 50 (floorstanding) speaker to 22's (bookshelves)?
I would think you would want to compare to another floorstanding design. The Infinity's have dual 8" woofers, so you might want to compare against something that might compare in the bass dept.
I believe the Beta's run about 650-700 pair if you look around online. they list for around $800 if I recall correctly. The m50's can be had for around $660/pair and the m60's at $860/pair if you order from Axioms Factory Outlet and save 10%. Five or more items from Axiom will get you another 5% off the order, but I'm not sure your ready to do that...
