Powerbass OE-400 4'' midrange oem replacement speaker

PowerBass OE-400 4" High-Efficiency Replacement Coaxial Speakers

2-Ohm OE Speaker Upgrade Designed for use with Factory Radios

The PowerBass OE-400 is a premium 4-inch coaxial speaker engineered specifically as a high-performance replacement for factory-installed speakers. Unlike standard aftermarket speakers, the OE series features a 2-ohm voice coil, allowing it to draw more power from factory amplifiers and head units. This results in significantly higher output, better clarity, and a fuller soundstage without needing an external amplifier.

Designed to fit into the tightest factory locations such as dash corners and rear pillars, the OE-400 is the perfect "drop-in" solution for modern vehicles that use low-impedance audio systems.

Key Features

• 2-Ohm System Sensitivity: Specifically designed to work with modern factory-amplified systems. This impedance match ensures you get maximum volume and efficiency from your stock radio.
• Injection Molded PP Cone: The carbon fiber-infused polypropylene cone is lightweight yet rigid, delivering punchy mid-bass and clear vocals while resisting the humidity and temperature extremes of a car door.
• 1" Aluminum Dome Tweeter: Features a high-grade aluminum dome tweeter for smooth, natural high frequencies.
• Nylon Fiber OEM Composite Basket: The non-resonant basket design prevents vibration and ensures a perfect fit in shallow factory locations.
• High-Flux Y30 Strontium Magnet: Provides a powerful magnetic field to drive the voice coil with precision, resulting in better transient response and detail.
