Hi-Vi Research D620 6.5" Autosound Component System - Pair

• German crafted 6.5" Paper/Kevlar fiber cone
• Large 3" diameter voice coil for increased power handling and control
• Rubber surround
• Shallow woofer moutning depth of 61mm (2.4")
• 1" Textile dome tweeter, use either as flush mount or with wedge mount
• 12/18dB 2-way 2.2kHz crossover
• Multiply tweeter connections to adjust tweeter output levels
• Decorative metal grill
• Includes screws, spacers and gaskets
• Power (RMS/MAX) 60W / 120W
• Frequency response 58Hz-20kHz
• Sensitivity 86dB (1W/1m)
• Nominal Impedance 4 ohm
• Due to the large voice coils on the woofers, this system will probably need more power than can be provided by a head unit alone.

The D620 component system is designed for detailed and accurate sound reproduction. The large 3" diameter copper wire voice coil is a lot of motor for a small driver. The large voice coil will be very responsive and will dissipate heat. The Paper/Kevlar cone provides a vivid, yet natural sound. They tonal characteristics of this cone material will provide clean and accurate midrange reproduction.

The 1" textile dome tweeter has a special rear chamber to reduce internal reflections and provide a lower resonance frequency that allows for the 2.2kHz crossover frequency. Textile domes offer a softer and more natural sound and are a good mate for this woofer with similar qualities.

This is a high end system and we're sure you'll be thrilled with the results.
