Description

Product Overview

Add mid-bass impact and high-frequency detail to a vehicle, motorcycle, or boat audio system with the DS18 8HD800NCFD-8 8-inch coaxial hybrid speaker. Its water-resistant carbon fiber cone handles the mid-bass, while the built-in compression horn driver adds high-frequency output in one two-way speaker.

Key Features & Benefits

  • Two-way coaxial design: The integrated horn driver combines mid-bass and high-frequency output in one speaker.
  • Water-resistant carbon fiber cone: The cone is designed to resist moisture and environmental exposure.
  • Four terminals: Separate terminal pairs for the midrange and driver offer flexibility when planning signal paths and system tuning.
  • Sold individually or in pairs: Choose a single speaker or a pair for your system setup.

Why Choose This Product?

The 8HD800NCFD-8 brings a mid-bass speaker and compression horn driver together in a single coaxial unit. Its water-resistant cone makes it an option for marine, motorcycle, and automotive installs where exposure to moisture is a consideration.

The four-terminal layout gives you separate connections for the midrange and driver when planning your system’s signal path. The integrated horn driver also provides high-frequency extension without requiring external crossover components, according to the product details.

Installation & Compatibility Notes

Plan for an 8-inch speaker and confirm that your mounting location and enclosure suit the installation. The woofer and driver are each rated at 8 ohms; check your amplifier and system configuration before connecting them. The four terminals are split between the midrange and driver.
