PowerBass S-4002 4" Coaxial Speakers

Product Overview

The PowerBass S-4002 4" coaxial speakers combine a woofer and tweeter in one compact speaker, helping you upgrade factory locations without a large mounting footprint. Their shallow design, black finish, and OEM drop-in replacement design suit installations where space and a factory-like appearance matter.

Key Features & Benefits

• Compact coaxial design: The integrated woofer and tweeter create a single speaker package for a small mounting area.
• DDC-coated paper cone: The two-layer cone’s Dynamic Damping Coating helps control cone breakup and improve midrange consistency.
• Silk-dome tweeter: The 0.75" tweeter provides high-frequency output in a slim design.
• SEL tweeter ring: The Sound Expander Lens enhances high-frequency dispersion for a wider listening area.
• Shallow mounting depth: The space-conscious design can help when room behind the mounting surface is limited.
• Black, tooled basket: The Flat Black finish gives the speaker a clean, factory-like appearance in the installation area.
