Sboarder,

The bookshelf speakers are larger than they look in the pictures.

If you want to play loud AND have a relatively small package, look no further than the M22. I have a pair of these and they can easily blow my eardrums out without distorting. I have a smallish room at roughly 13'x12', but I'm positive they could do the same thing in a larger room, too. My receiver is only rated at 70W/ch, too.
