RECONE INSTRUCTIONS

All Cerwin-Vega Mobile Stroker series woofers have been designed to be eld

serviceable. This new design provides a fast and simple way to rebuild woofers

in the eld using only the provided allen tool.

BEFORE YOU START

Make sure your work area is clean and free from any dirt or metal particles.

Stroker woofers can attract metal particles from a few feet away. Metal par-

ticles in the voice coil gap permanently damage the speaker and will void

any warranty. If the woofer is going to be left disassembled for any length of

time we recommend covering the voice coil gap with plastic wrap until it is

time to rebuild the woofer

We recommend that you use BLUE Loctite thread lock 242 on all Stroker

hardware.

RECONE STEPS

Using the provided allen tool, remove the six allen bolts attaching the cone

assembly to the magnet. Please see illustration below.

Carefully lift the cone assembly off of the magnet. Please see illlustration

below.

Make sure that the voice coil gap is clean. If the prior voice coil was melted

or damaged any remaining material must be removed prior to installing the

new cone assembly.

Align the cone assembly terminals with the Cerwin-Vega Mobile logo on the

magnet boot and very carefully lower the cone assembly down into the voice

coil gap of the magnet. Special care must be taken not to scratch or damage

the voice coil. The assembly should slide into place with no friction between

the cone assembly and the magnet.

Align the screw holes in the cone assembly with the screw holes in the mag-

net and gently hand tighten all six allen screws. Please see illustration be-

low

6. Using the provided allen tool, tighten the six allen bolts attaching the cone

assembly to the magnet in the order shown below. Do not over tighten.

7. Carefully move the woofer cone in and out, checking for any obvious rubs.

Be careful to apply even pressure. It is easy to apply to much pressure on one

side of the cone and cause a rub. If there is an obvious rub go back to the

beginning and start again.

SQL ENCLOSURE GUIDE

Warranty

Cerwin-Vega Mobile warrants all speakers to be free of defects in material or workmanship

for a period of 1 year.

Warranty Procedure:

Cerwin-Vega Mobile strongly suggests all warranty claims should be handled through

an authorized dealer. Because of the technical nature of our products, performance

problems can often be the result of improper usage or installation. An authorized

retailer can help determine if this is the case and will save you the time of returning

an item that is not actually defective.

For all STROKER subwoofer models the cone is to be removed from the magnet.

All returns must have the serial number taped to the cone. The serial number can be found

on the basket and underneath the spider attached to the top of the magnet plate.

Please remove the sticker and tape it to the cone. This process will save everyone on

shipping costs and allow us to check and replace speakers much faster.

Shipping:

Once you have your RA number, ship your return to:
