Product Description

SPECIAL ORDER ITEM

Features

  • Exceptional cone excursion – ensures high sound pressure levels and impressive low-frequency reproduction

  • Hybrid flat woofer concept – a perfect balance between a powerful subwoofer and a mid-woofer driver that covers a frequency range from 25 to 500 Hz

  • Flexible connection – chassis with 2 x 2 Ohms dual voice coil always offering the right solution for every amplifier configuration to achieve maximum performance

  • Minimum installation depth – an innovative basket design with only 47 mm installation depth for the use in restricted mounting spaces

  • Compact dimensions with maximum performance – despite the small outer diameter, this woofer comes with the same cone area known from typical 200 mm chassis

  • Lightweight polypropylene cone which provides essential stiffness for phenomenal sound performance

  • High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing

  • Powerful magnet system for high efficiency and optimum impulse response

  • Perfect for difficult applications – e.g. can be installed under the seats in various BMW models or as front subwoofer in Mercedes cars
