The VR series itself was designed to give car audio enthusiasts the most bang for their buck, fitting in the mid price and quality range of JL Audios evolution car speakers. The VR600-CXi is comprised of a 6" woofer with grill, 1" dome tweeter and a built in crossover network. The 6" woofer has a mica-filled polypropylene cone, 1" voice coil and butyl rubber surround. The 1" treated textile soft dome tweeter uses a neodymium magnet to keep its size at a minimum, and is ferrofluid cooled and damped within its compact housing. Unlike the VR600-CSi component verson of this speaker offered by JL Audio, the VR600-CXi does not have a segregated crossover network with multiple settings giving you less control over which frequencies are played through the woofer and tweeter. However, the lack of this extra component makes installation that much simpler and eliminates the cost of components that not everyone will fully utilize. The VR600-CXi does have the same woofer as the VR600-CSi, but the CSi uses a 3/4" silk dome tweeter rather than the 1" treated textile. However this tweeter is universal for all coaxial speakers in the VR series.
