Owner’s Manual
An Introduction Thank you for purchasing a JL Audio W7 subwoofer driver. The W7 embodies JL Audio’s commitment to pushing the envelope of speaker technology, with eight patented technologies, a design patent and a completely unique set of component parts. Each W7 model has been meticulously engineered to reproduce sub-bass with extreme fidelity at any volume level, provided it is installed and tuned properly.

W7 Mounting Guide Please review the mounting procedures thoroughly before attempting to remove the speaker from its shipping baffle. The W7 mounts like no other speaker and care must be taken to follow these instructions precisely. 2e 2c 1 2a Step 1: Your Tools When you remove the W7 from its shipping carton, it is attached to an MDF baffle board. Make sure you keep this baffle board and all the packing material in the unlikely event that the W7 ever needs to be shipped back to JL Audio for service.
Step 5: Ready to Install You are now ready to install the W7 into its enclosure. The parts are shown below. Step 6: Connect the speaker wires and place the W7 into the enclosure Connect the positive wire to the red terminal and the negative wire to the black terminal of the W7 (picture 6a). The 13W7 (not shown) has dual voice coils and must be wired with its coils in series or in parallel. Once the speaker is wired, gently lower it into the enclosure (picture 6b).
