Infinity plus Sound Dampening Material Bundle

This Sonic Electronix Exclusive Bundle showcases a pair of 3.5" Infinity Kappa Series Car Speakers. These car speakers are rated at 70 watts RMS of continues power (per pair) and 210 watts of Max power (per pair). These speakers are equipped with a rubber surround for durability and longevity. The speakers also feature a Woven Glass Fiber cone woofer, that will improve the speakers linearity for better performance. With a 2 Ohm impedance and 1" Edge-Driven Metal Matrix Diaphragm dome tweeter, these Infinity speakers are perfect for anyone looking to enhance their factory car audio system.

In order to improve the all around sound of your audio car system, this bundle also includes two 10" x 10" pieces of NVX Sound Dampening Material. Sound dampening material is key to reducing the rattles and shakes in your car. It effectively reduces the amount of road noise that is let in through the thin panels of your vehicle. It also lessens vibrations that are created by playing music through your speakers. It works by adding weight to the desired panel, which lowers the resonating frequency. You will notice by adding this material to your car, your sound system will likely get noticeably louder. If you have subwoofers, this is the perfect kit for your vehicle.
