Tips:
• The tweeter responds immediately to control increases but very slowly to
decreases. For decreases, the speed will be increased by switching the speaker
off for a while, such as fifteen or so minutes, before repowering and listening
at the new setting.
• Too much bass? First make sure the tweeter control is all the way up. Then try
setting the woofer switch to the middle position, or moving the speakers away
from walls, and particularly out of corners.
• Not enough bass? Try moving them closer to walls or corners.
• Staging problems? Try:
o
Moving them four or five feet out from the front wall.
o
Changing the amount of back-tilt
o
Adding absorption or diffusion at the side wall first reflection points
• Upper treble response can be rolled off to taste by reducing toe-in.
• Experimenting with the back-tilt can also tailor the response, but will produce
changes that are more radical than from changing the toe-in; in particular, a
severe midrange dip will be created when significantly off the ideal tilt angle.
Also, changing the back-tilt away from a straight-facing aim will degrade time-
alignment.
• When there is too much deep bass, and the only solution is to deviate from an
equilateral triangle to get the speakers away from side walls, this will obviously
narrow the soundstage, but could be worth it.
• For recordings made using a Blumlein microphone arrangement, a 90° angle
between the speakers is best, although this is hard to arrange in most rooms
without sitting very close to the speakers, which not everyone will want to do,
and where the drivers do not converge as well in time. In many cases, a very
wide arrangement is just more enjoyable for the extra soundstage width, and
the image is always crisp enough to support this without degrading focus.
• For the most holographic effect, try two-microphone recordings, especially
binaural!
