Placement

Subwoofers produce "non-directional" audio frequencies. Unlike other speakers, 
they produce a sound that does not seem to come from any specific point but this 
does not mean that you can place your subwoofer anywhere in the room - quite to 
the contrary. Frequency response and output are influenced by placement.

As each room is acoustically unique it is recommended that you experiment with 
the placement of your James subwoofer to optimize its' performance. Frequency 
peaks and/or nulls (boominess or lack of bass response) can usually be corrected 
with proper subwoofer placement. Often, finding the best subwoofer location for 
a given room is to first temporarily place the subwoofer in the listening position 
'sweet spot'. Walk around the room and listen at different locations for the best 
'smooth' bass response. Place your subwoofer at or near that location.

When placing your subwoofer in its final position, make sure the speaker faces 
forward, standing upright. Do not place the subwoofer near sources of heat 
and/or moisture.

Care and Maintenance

Special care should be taken to not scratch or damage your subwoofer. Cloth grills 
should be removed prior to cleaning and cleaned separately using a brush and low 
lint collector. Avoid direct contact with the speaker drivers to prevent possible 
damage. Never use paper products or anything abrasive to clean your speaker's 
finish. Use a damp lint free cloth if necessary.

For high gloss finishes we recommend using a mild spray cleaner and soft flannel 
cloth. Small surface scratches can often be buffed out with care by hand. Use only 
liquid polish suitable for fine automotive finishes. CAUTION: The use of any 
polishing product could cause the finish to rub through. Please contact James 
Loudspeaker directly if you have any questions regarding the care and 
maintenance of your speakers.
