YEAR from the date purchased by the end user, and limited to the original retail purchaser of
the product. Product found to be defective during that period will be repaired or replaced by
MTX at no charge. This warranty is void if it is determined that unauthorized parties have at-
tempted repairs or alterations of any nature. Warranty does not extend to cosmetics or finish.
Before presuming a defect is present in the product, be certain that all related equipment and
wiring is functioning properly. MTX disclaims any liability for other incurred damages result-
ing from product defects. Any expenses incurred in the removal and reinstallation of product
is not covered by this warranty. MTX’s total liability will not exceed the purchase price of the
product. If a defect is present, your authorized MTX dealer may be able to effect repairs.
PLACEMENT OR POSITIONING
Your new subwoofer will work well in a variety of locations. However, placement in your lis-
tening room will affect is performance. Since the wavelengths of sound reproduced by your
subwoofer are large compared to its size, those sounds are omni-directional in nature. This
means that locating your subwoofer in relation to your left and right main speakers will not
affect the directional cues which they provide.
Because the sound you hear is combination of direct sound from the speaker and reflected
sound from the wall, ceiling and floor of your listening room, placement of the subwoofer in
relation to room boundaries changes the balance of what you hear at low frequencies. In that
low frequency range, the dimensions of most rooms are comparable to the wavelengths of
those sounds. As sound propagates and reflects in the room, “standing waves” are created
at frequencies where the wave length of sound or multiples of the wave length are equal to
one of the dimensions of the room. At your listening position, these standing wave patterns
of reflected sound add together in and out of phase causing large variations in the response
that you hear.
Proof of purchase is required when requesting service, so please retain your sales receipt
and take a moment to register your product on line at mtx.com.
SPECIFICATIONS
Driver Size: 8”
As a general rule, locating your subwoofer near the corner of the room will increase its overall
output, but will excite more standing waves in the room and may result in a more uneven
response. Locating your subwoofer along a wall will usually mean less acoustic output but
a somewhat smoother response. A middle of the room location would suggest the smooth-
est response with the least output capability. Of course, any location will be a compromise
between acoustic performance and the aesthetic blend of the subwoofer enclosure with the
decor and furnishings of your room. Don’t be afraid to experiment with the location of your
subwoofer in your room for the best results at your listening position. As with any other listen-
ing test, use program material that you are familiar with that has substantial bass content.
Frequency Response: 50Hz - 150Hz
Lowpass Crossover: Adjustable from 50Hz - 150Hz
Inputs: Line level and speaker level
Amplifier Power: 120W Peak Music Power
Dimensions: 13 3/4”H x 10”W x 13 3/16”D
Unit Weight: 16.5 lbs.
SET-UP AND ADJUSTMENT
After you have selected an initial location for your subwoofer and have connected it into your
system, have a seat in your normal listening position and have someone help you with the
following adjustments:
A) If you are using the line level inputs and your main speakers are receiving a full range
signal, set the subwoofer crossover frequency control to its full counterclockwise position of
50Hz.
B) Set the gain control to the full counterclockwise position at “minimum”.
C) Turn off the loudness control and set the bass tone control on your main amplifier to the
flat position.
D) Use familiar program material that has substantial bass content and play your main sys-
tem at a moderate volume level.
E) Slowly rotate the subwoofer level control clockwise until a good balance is achieved be-
tween the low frequency output of your subwoofer and the mid bass and upper frequencies
from your main speakers.
F) Slowly rotate the subwoofer crossover frequency control clockwise to attain the best blend
between the level of the subwoofer and the main speakers in the midbass crossover region.
Advancing the control too far will cause a “boominess” in the overall sound and will add an
unnatural “chesty” quality to male voices.
CARE AND MAINTENANCE
Use the following guidelines to maintain the appearance of your subwoofer. Use a soft, damp
cloth to clean the speaker cabinet. Avoid using harsh detergents or cleaning fluids. Do not
vacuum any of the speaker components. Permanent damage could occur.
