SL-500,
250 mm (10") Subwoofer Driver
To
achieve well extended, satisfying low bass from very small enclosures
has long been a challenge for car audio manufacturers. AVI's radical
new SL-500 meets the challenge, with a major departure from conventional
thinking.
Mounting
depth has been substantially reduced by positioning two magnets
within the chassis, instead of one on the back. Dual voice coils
allow maximum flexibility and are wound on a composite polyamide
former for high power handling and output. The cone material is
deeply convoluted to increase its tortional rigidity, and the
SL-500 front suspension is the first in the world to use anechoic
rubber material, to provide improved definition.
This is a dual voice coil subwoofer driver with an extremely shallow
mounting depth of just 92 mm (3.6"). It may be connected
in parallel (2 ohms), series (8 ohms) or at 4 ohms each from two
amplifier channels (not recommended). The suggested operating
range is 45 to 430 Hz.
For "stealth" installations, the remarkably small enclosure
required for the SL-500 dramatically increases the number of practical
mounting locations in any vehicle.
