Are your X-1/GrandSLAMM’s dedicated for a home theater?
Are you going to sit on a couch, or will there be multiple rows of chairs?
If it is a couch, you should center the loudspeakers on the center position of the couch.
Multiple rows of chairs - In this case you should dedicate the 1.2 times equation on your second row
of seating. Now more people will enjoy the power of your X-1/GrandSLAMMs .
Do you still want to listen to 2 channel music at its highest quality? In this way you can enjoy a
great time aligned sound from that second seat.

RIENTATION
Speaker placement and orientation are two of the most important considerations in obtaining supe-
rior sound. The first thing you need to do is eliminate the side walls as a sonic influence in your system.
Speakers placed too close to the side walls will suffer from a strong primary reflection. This can cause out-
of-phase cancellations, or comb filtering, which will cancel some frequencies and change the tonal balance
of the music. A good place to start is with the speakers about 18” from each wall and, if you need to move
them relative to the side wall, move them away from the wall, not closer.
A very important aspect of speaker placement is how far from the back wall to place the speakers.
The closer to the back wall the more pronounced the low bass energy and centering of the image will be.
However, this comes at a definite reduction in stage size and bloom, as well as a deterioration of upper bass
quality. You must find the proper balance of these two factors, but remember, if you are partial to bass re-
sponse or air and bloom, do not overcompensate your adjustments to maximize their effects. Overbalanced
systems are sometime pleasing in the short term, but long term satisfaction is always achieved through
proper balance.
The X-1/GrandSLAMM is designed for maximum phase coherence and pulse replication
accuracy when they are aimed directly at the listener or microphone. Thus, your X-1/Grand-
SLAMM should be “toed in.” In other words, the listener, when seated in the listening position,
should just barely see the surface of the inner side of X-1/GrandSLAMM. Toeing in the speakers
provides dramatic improvements in resolution of low level detail in the midrange, as well as dra-
matic improvements in sound staging performance.
