   Well, obviously you want to play louder than your speaker/amp
   combination will play.  Whether you buy more efficient speakers
   or a more powerful amplifier would be highly dependent on WHICH
   speakers and amplifier you own and which you value more.   
   These are matters of highly personal taste, but I'd be glad to
   make a suggestion about like I'd be glad to choose your
   girlfriend for you.

   If I recall the amp was a Fisher.  This might just be a truly
   cheesey amplifier with high internal impedance, more commonly
   known as poor damping.  It might sound OK with sealed speakers or
   vented/passive radiator types as long as their resonance is low
   enough.  

   When a poorly damped amp tries to drive a vented or passive
   radiator speaker at frequencies below the speakers resonance, the
   cone or passive radiator is pretty much unloaded and flaps in the
   breeze.   

   I've honestly never heard complaints against the Polks unless you
   really brutalize them or drive them with lousy amps....you may
   want to see if you can borrow an HK, Adcom, etc. before you
   change out the speakers.  Ordinarily I'd say you are likely
   looking at new speakers, but if the amp is an old Fisher I'd cast
   a real fishy eye at it.
