That is a small room. Stay with the 1.7. If you feel the amp is not up to the task of handling them.....try one with more current. If you feel it is an up grade, then you made your decision.
Since you are into rock, you might just consider a subwoofer. It might give you the omf you are looking for. Crossing over at 60hz or so will relieve the low demand from your current amp as well as free up the panel of the frequencies below 60....providing a possibly better sounding upper bass and mid. Not to mention that a sub can also seem to open up the sound stage, too.
