6.5" 2-way bookshelf speaker with a sensational soft dome tweeter for extreme accuracy. Pinnacle's own patented Diaduct bass port ensures superior bass from a small speaker. Can be used as main speakers in your Home Theater / audio system or as your primary set of music listening speakers. The extreme accuracy of the AC650 makes it a great choice for recording or music studios.    
 

"Their stereo presentation was flawless ... I cannot imagine another speaker in its price range that can surpass its overall sound quality." "... I tried to find their Achilles heel, but it eluded me. It ... could go toe to toe with others many times its price and more than hold its own." - Julian Hirsch - Stereo Review
