The sound from a properly aligned loudspeaker reaches
the listener with the audible frequencies correct in both time
and phase. This lack of phase and time distortion contributes
to a more accurate sound, but also makes listening a the
proper height more important than with a nonaligned design.
A characteristic of all properly aligned loudspeakers is that
they are perfectly aligned at only one listening height. The
further away your ears are from this perfect alignment
height, the less accurate the speaker will be in the time and
frequency domains.
The Model 2Ce Signature II is aligned for a 33 inch lis-
tening height when placed on a 3 inch high base. It has a
vertical listening window extending about 3 inches above
and below the alignment height where the sound of the
speaker will still be quite good. Outside of the vertical lis-
tening window, the sound and performance of the speaker
will be compromised.
If your ear height is above 33 inches at your normal lis-
tening position, the speakers can be leaned back according
to the following instructions to raise the optimum listening
window up to your ear height.
1. Measure the distance from the listening position to the
speakers and the height of your ears when you are
seated at the listening position. (Ear height is roughly
equal to the height of the tip of your nose).
2. Find the values closest to your actual measurements on
the chart at the right.
3. Follow the horizontal line across from your distance and
the vertical line up from your ear height to the point
where they intersect. The graph lines numbered from 0
to 3
1/2
indicate how many inches the top of the speaker
should be behind the bottom of the speaker to center the
six inch listening window at your listening height and
distance.
4. Adjust the length of the base’s front and rear spikes to
lean the speakers backward the proper amount.
5. As an example of how to get the proper amount of lean:
a. Tie a nut to a piece of thread about four feet long.
b. Hang the thread and nut from the back of the speaker
and measure the distance the nut is away from the
bottom of the speaker as shown in the diagram. This
measurement is the amount of speaker lean. (For clar-
ity, the lean in the diagram has been exaggerated and
the base is not shown).

Two contour controls are located on the aluminum dress
plate at the rear of the Model 2Ce Signature. The upper con-
trol adjusts the tweeter level and the lower control adjusts
the midrange level.
The contour controls are used to compensate for a bright
or dull room that could not be corrected with speaker place-
ment, acoustical treatments or other passive means. The con-
trols are limited in their effects and even at maximum rota-
tion they will not take the response of the speaker out of a
plus or minus 3dB envelope. Changing the contour
controls will not affect the detail, imaging or phase per-
formance of the speakers due to their unique incorporation
into the crossover circuitry.
When using the controls, we recommend that you start
with small adjustments and only change the midrange con-
trols or the tweeter controls before listening for the effects
of the change. By changing only one pair of controls, you
will be able to determine the effects that each pair of con-
trols have upon the sound of the speakers in your room.
