The SR-5.2 is a 2-way 5" component system.  It uses the WR-5 double magnet woofer.  This woofer has great midrange sound that allows it to be used in a midbass/midrange combination.  The CR-104 tweeter is a soft dome tweeter with a double neodymium magnet system.  It has great clarity and detail with precise imaging.  The system comes complete with the XR-2.2 2-way crossovers.  More information on the individual components can be found by clicking on the links.
