are you serious?imy first speakers were Polk Audio Monitor 70 and I must say the sound is amazing even when driven whith only 90 watts(Marantz sr 5004),these speakers are rated at 275 watts.so do the math and I don't use any subs at all.I must add that a friend of mine had a pair of Infinity Primus,the question is ,I sold him the Marantz but he was not happy with the sound(Marantz+Infinity Primus),but guess what,i upgraded my speakers to RTI A7 and lucky he I sold him the Monitors as well.He was impressed by the change,he can hear the difference in every detail.I'm sured that there are other more expensive speakers in the market that sound better than the polks but I am a polk fan and for the price range and sound quality I consider them among the best!
