Integrates woofer and tweeter as a seamless acoustic system.
Compact neodymium magnet structures
Deliver superb sound quality output from compact Magnetic-finite-element optimized structures.
Copper-clad aluminum woofer voice coils
Provides low-mass, long Xmax, and optimized DCR while maintaining power handling.
