Features:
Rockville W8K5S2 K5 Series 8 2-Ohm Car Subwoofer
Peak Power Handling: 800 Watts
Program Power Handling: 400 Watts
CEA Rated RMS Power Handling: 200 Watts
1.5 4-Layer Black Aluminum Voice Coils Wound with OFC (100% Copper) Wire
The wire we use to wind the voice coil is imported from Japan which is way better quality than the standard China wire
30 Oz High Quality Magnet
Cast Iron Basket With Black Sanded Finish
Fiber Reinforced Ultra Stiff Black Non-Pressed Paper Cone ?C This cone is very efficient which makes the speaker sound louder even without requiring a lot of power to push it
Thick Foam Surround Provides Incredible Sound Quality With Minimal Distortion
Blue Stitching Cone Reinforcement Ensures Long Life
Paper Dust cap is light weight and efficient helping the sub to play louder even if your amp is not so powerful
Chrome-Plated Binding Post Terminals – These are the best terminals on the market and they accept any gauge wire
Impedance: Single 2-Ohm Voice Coils
Vented Hole on T-yoke Enhances Heat Dissipation
Rubber Boot Magnet Covers Make the Woofer Look Nice and Protects the Magnet
Mounting Gasket with Rockville branding looks great and Makes it Easy To Mount the Subwoofer Air-Tight
High BL Magnetic Motor Gap
We use the highest grade black glue that handles extremely high temperatures which allows our woofer to handle even more power than they are rated
