Rockville RV4.3A 4" 3-Way Car Speakers, 500W, 4 Ohm, Polypropylene Woofer, Butyl Rubber Surround, With Grilles, CEA Compliant, Perfect for Car Audio

Description: Rockville car audio speakers utilize the latest in speaker technology for superior sound quality. We use top quality polypropylene cones which are known for their high damping qualities. This means they can have a controlled break-up, which results in a smoother high frequency roll-off. Our Flexmotion Butyl Rubber Surrounds give the speakers a smooth response with minimal distortion. For smooth and extended high frequency sounds we used high temperature PEI dome tweeters with ferrite magnets. The RV-A series speakers are designed with superior SPL response and extremely high power handling making these perfect for use with the amp built into your receiver or with a high powered external amplifier. Due to their shallow mount design, these speakers fit in 97% of all vehicles. CEA Rated. Rockville car audio speakers are CEA rated, what that means is that the Consumer Electronics Association recognizes these speakers to be accurately rated and meet their rigorous standards for wattage, SPL and frequency response. So while other manufacturers state out-of-this-world wattages on their products, you can rest assured that your Rockville speaker will work up to spec. and exceed your expectations.

What so special about Rockville Speakers in engineering terms. The acoustic center of a driver is the point in the driver from which the sound appears to originate. What is crucial in a good multi-element design is the difference between the centers of the drivers. This is called relative acoustic offset. A good speaker design features phase accuracy in and around the crossover point, because the interaction of the drivers is most affected by the SPL magnitude and phase in this area. The Rockville designs allow for wide dispersion of the sound for complete musical immersion.
