Infinity 429I 150W (Peak) 4 -Inch 2-Way Speaker (Pair)
The Kappa 42.9i 4"" 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 midbass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.
