This set of Micca MB42X G2 Passive Bookshelf Speakers is a nice pair of speakers that are a pleasure to listen to. They come with a 4" Carbon Fiber, Rubber Surround Woofer, and a 0.75" Silk Dome Tweeter and are rear ported; The Frequency Response is 55Hz-20kHz; Impedance: 4-8 Ohms; Sensitivity: 86dB, the Power Handling is 80 Watts (Each)and the Dimensions are 9.5" (H) x 5.8" (W) x 6.5" (D)
They have a nice low end, but really open up with a subwoofer and a little volume, you don’t need to blast them, they just sound better, with a smooth and clear sound. It’s a real pleasure listening to them.
