Caution
The terminal plate states a maximum fuse value of 5 amps Type 3AG ("normal" or "fast blow") for the midrange
and 2 1/2 amps for the tweeter. The bass section does not require fusing protection. This fuse value should never be
increased or bypassed. Do not use slow-blow fuses. BURNED OUT MIDRANGE OR TWEETERS ARE NOT
COVERED UNDER THE WARRANTY.

Speaker Placement
Proper speaker placement and room acoustics can have a greater effect on a music system than upgrading one of
the components in the system. Unfortunately, there is no definitive guideline which will cover all possible listening
rooms. Some experimentation is required for locating the optimum position. The following are a few general
guidelines:

Bass Response
Play a CD with repetitive bass. Try the speakers in several possible locations in the room. Begin experimenting
with the speakers about 3 feet from the front wall. Try moving the speakers forward or backward in increments of 6
to 12 inches. One position in the room should be noticeably better than others. Also experiment with your listening
location to avoid standing waves.
Due to standing waves, dips and peaks in the bass and midbass are a fact of life. Each room has its sonic
signature depending upon the size, shape and construction. One solution is electronic equalization to deal with room
aberrations. Many of the newer receivers and processors incorporate a microphone and automatic EQ that will
correct frequency imbalances. However, this approach has drawbacks and is not well accepted by most
audiophiles. There is another and better solution.
Multiple subwoofers are commonly used to smooth room bass response. Although an expensive solution, this
technique has been proven to be superior to EQ of a single subwoofer. Using the same fundamentals of acoustics,
Magnepan has a solution which can fine-tune the bass and midbass of our floor-standing models--- the Maggie
Woofer (DWM and DW 1).
More information is available on the Magnepan website to describe how the Maggie Woofers can be used to give
you smooth bass and midbass in the most difficult of rooms.
