8W1v3-4 Subwoofer Driver

Congratulations on your purchase of a JL Audio subwoofer component. Your JL Audio subwoofer

is a precision loudspeaker which has been engineered to produce the highest quality sub-bass

performance in your vehicle. Authorized JL Audio dealers have extensive technical information

for many different applications of your new speaker. They also have the knowledge, skills and tools

to build a high-quality enclosure that will maximize the performance of your speaker. We highly

recommend that you have your enclosure built by an authorized JL Audio dealer.

Inside you will find specifications and two recommended enclosures for your speaker; one is a

sealed enclosure, the other is a ported design. Both types of enclosures will give you excellent sound

quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely

tight, but the ported enclosure will produce 3dB more output at the same power if you have the

extra space to work with.

RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER: 30W 60W 125W 250W 500W 8W1v3 MEDIUM GRAY (MINIMUM): From a reliability standpoint, this zone represents a very comfortable operating power range for each driver. This level of power will not stress the woofer but will not extract all of its performance potential, either. Use of less than the minimum power level will not damage the woofer, but may result in unsatisfactory performance.
