RPX4 | 4" 120 Watt Coaxial Car Speakers - Pair

  • The Skar Audio RPX4 are 4" 2-way coaxial car speakers engineered and designed for an upgraded listening experience. The sport series of RPX speakers have a sleek design and are reliably powerful, providing rich and clear sound as an upgrade to existing factory speakers. They work great on factory radio power or amplified power, and feature high quality build materials such as a microfiber paper cone and premium butyl rubber surround.

    The RPX series has been a customer favorite for many years most notably due to their impeccable sound reproduction. These 4" speakers utilize a 1-inch KSV copper voice coil as well as an aluminum dome tweeter for crisp and clear highs. Furthermore, the RPX4 coaxial speakers are equipped with a premium ferrite magnet, providing the driving force to enhance your vehicle's sound stage.

Great budget coaxials

Bought for a boombox I’m putting together. Sounds great sealed. Perfect for the shoe shine box I found at goodwill. I’ll most likely use these again. Bonus were the grills. Used silicone to seal them up around the grill housing and where the speaker mounts onto them. Added more silicone (as pictured) when mounted on the box. I’ll probably use the same Bluetooth device as recommended on the previous review (from Jose).
