No matter what type of music you enjoy, you'll love how the JL Audio ZR650 CSi sounds in your car. Its woofers are surprisingly bassy for a 6.5″ speaker, and don't overpower the higher-frequency sounds while its aluminum-domed tweeter produces clean audio in the high ranges. Additionally, the tweeter offers five levels of attenuation and four levels of midrange presence, which gives you a total of 20 possible sound customizations. With the ZR650 CSi, you'll feel like you're in the middle of a concert hall, even while speeding down the road at 65 miles per hour.
