reasons, we advise all YAMAHA product owners that any service required should be performed by an
authorized YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification
or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any
form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and

Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this
buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the
unit.

2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●
Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or
plastic (where applicable) components may also contain traces of chemicals found by the California Health and
Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR
ANY REASON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes
or expose eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands
before handling food.

■ DISASSEMBLY PROCEDURES
(Remove parts in the order as numbered.)
● Disassemble of the Subwoofer
3. Removal of the Speaker
a. Set up the front panel ass’y in the direction of the
arrow, in Fig. 2.
b. Remove 4 screws ( w ) in Fig. 2, and remove the
speaker.
1. Removal of the Rear Panel Ass’y.
a. Remove 8 screws ( q ) in Fig. 1, and remove the
rear panel ass’y.
*
Arrow marks (
removed.
) are printed to identify the screws to be
b. Disconnect one connector in Fig. 1.
c. Disconnect the Speaker cord in Fig. 1.
Front Panel Ass’y
* When assembling the Rear Panel Ass'y, check to ensure
that the packing is not damaged so as to prevent air leakage from occurring.
2. Removal of the Front Panel Ass’y
The front panel assy is fixed to the cabinet with
dowels at 6 locations.
* As a screwdriver (for slotted head screw) is used
for removal, use special care not to cause damage
to the Cabinet.
a. Using the screwdriver insert in the gaps between the
front panel ass’y and cabinet (bottom side first), push
up the front panel ass’y.
b. Remove the front panel ass’y while taking it out.
(Front panel ass’y can not to remove completely.)
