I bought a pair of these from online car stereo in a 6.5 afew years back. I can say they do a great overal job for a small speaker.And better than afew others larger for bass respose.When using a amp of equal RMS rating.And installed in the right, air tight, sized enclosure.These play equal or better than a larger pair of infinity kappas in 5x7.Whats more is alot when I live in phx,az where its HOT like hell. In summer.180 degrees in a closed vehicle.Speakers can and do warp not the cerwin vega vegas.Mine have done the test of time for torture!From both eliments with real power.Still rockin hard today.Clear crisp highs. last of all.These do not require much from any amp.@ 70 watts rms are what the 6.5 is rated.And I have a 125 RMS running these and the infinitys.Just fine and for those who want to know about throw.These little guys have a good movement for such a small speaker.
