This listing is for a brand new & factory sealed Kappa 63.9i 6-1/2" 3-way speakers. This is for a pair of speakers (1 set).
The Kappa 63.9i 6-1/2" 3-way speakers feature light, but stiff woven glass-fiber woofer cones that won't flex or distort. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils produce tighter, snappier bass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.
