The very reasonably priced package includes two 6 1/2" woofers with grilles, two 3/4" tweeters and two crossover networks. The 6 1/2" woofer has a mica-filled polypropylene cone, 1" voice coil and butyl rubber surround. The silk dome tweeter uses a neodymium magnet to keep its size at a minimum, and is ferrofluid cooled within its super-compact housing. The tweeter is mounted using JL Audio's exclusive RSR mounting system allows the speaker to be rotated into the desired position, even after installation. The included 2-way crossover networks feature a natural low-pass roll-off, 3rd order high-pass circuit, adjustable tweeter output level and polyswitch tweeter protection. JL Audio also offers a 6 1/2" coaxial model in their VR series (the VR650-CXi), but the only common element between these systems is their woofers. The coaxial model features does not include an adjustable crossover, and has a 1" treated textile dome tweeter rather than the 3/4" silk dome. This tweeter is a also used on all the VR component speakers and is sold independantly as the VR075-CT. The crossover used is independant to this model.
