These are great little monitors if you are just getting started, or need a second pair of monitors for comparison when mixing. I have never blasted these and they have been in my closet for a few years. They are in great condition, work perfectly, and look good. I am asking $50.
From M-audio: We build the AV 40s with the same quality materials and precision electronics as our acclaimed M-Audio professional studio speakers. The audiophile-grade Class A/B amplifier architecture, ferrofluid-cooled silk cone tweeters, polypropylene-coated woofers, and dense wooden enclosures add up to big, defined sound that defies the speakers' small size.
