Product Highlights:
JVC CS-J620 - 2-Way Coaxial Car Speakers The JVC CS-J620 offers a Mica Cone and Hybrid Surround, built onto a steel stamped frame, to meet or exceed the performance of traditional OEM 6.5" speakers at an affordable price point.
The 30 watts RMS power handling of each speaker allows for use with a modest amplifier-- unlike an OEM speaker which would not reach full performance without one.
Built Better Than Typical Speakers In addition to the 1" Poly-Ether Imide balanced dome tweeter providing highs that other speakers cannot touch, it is strong enough to be used as such even in instances where high sound volume is required due its 22000 Hz frequency range capability.
To handle mid ranges and lows that can reach all the way down to 35Hz, this model's surround uses rubber/cloth material along with mica cone materials; these combined allow for proper function when showing off your favourite tunes!
