Rockville car audio speakers utilize the latest in speaker technology forsuperior sound quality. We use top quality polypropylene cones which are knownfor their high damping qualities. This means they can have a controlledbreak-up. which results in a smoother high frequency roll-off. Our FlexmotionButyl Rubber Surrounds give the speakers a smooth response with minimaldistortion. For smooth and extended high frequency sounds we used hightemperature PEI dome tweeters with ferrite magnets. The RV-A series speakers aredesigned with superior SPL response and extremely high power handling makingthese perfect for use with the amp built into your receiver or with a highpowered external amplifier. Due to their shallow mount design. these speakersfit in 97% of all vehicles.

CEA Rated.
Rockville car audio speakers are CEA rated. what that means is that the ConsumerElectronics Association recognizes these speakers to be accurately rated andmeet their rigorous standards for wattage. SPL and frequency response. So whileother manufacturers state out-of-this-world wattages on their products. youcan rest assured that your Rockville speaker will work up to spec. and exceedyour 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 soundappears to originate. What is crucial in a good multi-element design is thedifference between the centers of the drivers. This is called relative acousticoffset. A good speaker design features phase accuracy in and around thecrossover point. because the interaction of the drivers is most affected by theSPL magnitude and phase in this area. The Rockville designs allow for widedispersion of the sound for complete musical immersion.
