It is critical for proper performance that both speakers (left and right) be connect-
ed in proper phase. Note that one terminal on each speaker (the +) is colored red and
the other (the -) is colored black. Please make certain that you connect the red (+)
terminal on each speaker to the red (+) terminal of its channel on your amplifier or
receiver, and the black (-) terminal to the black (-) terminal. It is essential that both
speakers be connected in the same way to the amplifier (in phase). If you experience
a great lack of bass, it is likely that one speaker is out of phase with the other.

Usually if distortion is heard when the speakers are being driven at
loud levels, it is caused by driving (turning up) the amplifier too loud and
not driving the speakers with more power than they can handle. Remember,
most amplifiers put out their full rated power well before the volume control
is turned all the way up! (Often, turning the dial half way up is actually full
power.) If your speakers distort when you play them loud, turn down the
amplifier or get a bigger one.

The Mythos Gem XL is a tremendously versatile speaker which makes a perfect
left and right channel front satellite speaker (when used with a Definitive subwoofer)
as well as a superb rear or side surround speaker. We will describe the various
aspects of its use for both of these applications starting with the simplest instructions
first: for its use as a rear or side surround.

The Mythos Gem XL is designed to be extremely flexible in terms of their place-
ment when used as surround speakers. They may be used on the side walls, rear
walls or in the rear corners of the listening room. When placed along the side walls
the speakers should normally be located adjacent to or behind the listening position.
The speakers may also be placed near the rear corners of the room or located on the
rear wall. If you have your couch or listening position near or against the rear wall,
we suggest rear wall placement of the Mythos Gem XL with them positioned on
either side of the couch and in from the side wall. High placement is preferred;
however, midwall or floor placement is certainly acceptable. Normally speakers
would be hung on the wall with the input connection plate up against the wall,
however, the Mythos Gem XL may also be placed on shelves or stands. Of course,
experimentation is encouraged to get the best performance in your particular room.
As a starting point, we suggest mounting the speakers on the side walls behind the
listening position about 3-6 feet off the floor and halfway between the listening
position and the rear wall.

they are perfect for), one pair will normally be located on the side walls as described
