Overview

The Infinity KAPPA 83WDSSI is an 8-inch high-output subwoofer engineered for superior bass performance in compact automotive installations. With 400W RMS power handling and a 1200W peak capacity, this subwoofer delivers deep, accurate, and controlled low-frequency output. The Selectable Smart Impedance (SSI) switch allows easy selection between 2 ohms and 4 ohms for optimal amplifier matching without rewiring. The glass fibre cone, oversized dual stacked magnets, and Aero-Cooled voice coil ensure high-efficiency output, low distortion, and reliable long-term performance in space-constrained enclosures.

Key Features:

• 400W RMS / 1200W Peak Power – Delivers high-output bass performance from a compact 8-inch subwoofer, perfect for systems requiring substantial low-end impact.
• Selectable Smart Impedance (SSI) – Built-in impedance switch lets you choose between 2 ohms and 4 ohms, offering unmatched system matching flexibility without rewiring.
• Glass Fibre Cone with Rubber Surround – Lightweight yet rigid cone material enhances transient response and durability, while the rubber surround ensures long-lasting performance under extreme conditions.
• 30Hz – 175Hz Frequency Response – Wide low-frequency range delivers accurate, punchy bass that complements full-range speaker setups with deep extension.
• Oversized Dual Stacked Magnets – Provides strong magnetic force for high-efficiency output and greater excursion, translating to louder, deeper bass with improved cone control.
• Aero-Cooled Voice Coil Design – Advanced airflow technology dissipates heat more effectively, ensuring sustained performance and reducing the risk of thermal compression.
• 91dB High Sensitivity – Efficient design produces impressive output from modest amplifier power, maximising your system's performance.
• Optimised for Small Enclosures – Engineered for both sealed and ported enclosures, making it suitable for space-constrained installations without compromising low-end performance.

Ideal For

• Compact car audio systems requiring deep bass from limited space
• Sedans, trucks, and SUVs with small enclosure constraints
• Systems needing flexible impedance matching for amplifier optimisation
• Drivers seeking high-output, low-distortion bass performance
• Installations where rewiring is impractical or undesirable
