Product details

The Ground Zero GZHW 20-D1 is a compact car HiFi subwoofer designed for powerful bass reproduction in vehicles. Featuring a 20 cm (8 inch) driver that utilizes a double-layer fiberglass cone, this subwoofer offers excellent stiffness while remaining lightweight. This allows for precise bass response in the frequency range of 25 Hz to 250 Hz. Its compact dimensions of approximately 210 mm in diameter and 110 mm in installation depth make it ideal for various installation situations, while the high power handling of 700 watts RMS and 1500 watts peak ensures a powerful bass output. The dual 1-ohm voice coil configuration provides flexibility in wiring, and the high-temperature resistant aluminum voice coil supports heat management. The subwoofer is suitable for both sealed and bass reflex enclosures, making it a versatile choice for audiophiles looking to enhance the sound quality of their system.

  • Compact design for flexible installation options
  • Double-layer fiberglass cone for precise bass
  • High-temperature resistant voice coil for durability
  • Optimal performance in enclosures ranging from 15 to 30 liters.
