Speaker Placement
The design of the LSR4300 system lends itself to a wide variety of placement options.
Covered here is a typical stereo setup for near- to mid-field monitoring, where the mix position
is generally 1 to 1.5 meters (3 to 5 feet) away from the speakers.
While the exact stereo listening angle is largely a matter of personal preference, we
recommend the monitors be arranged to form an equilateral triangle as shown in the
illustration below.
Recommended stereo speaker positioning
The center of the high-frequency transducer should be at the same height (on-axis) as the ear
level of the listener. Ideally, they should be placed on suitable speaker stands and well away
from boundaries such as walls, ceilings, and large pieces of furniture. The LSR4328P and
LSR4326P are equipped with mounting points, to allow wall and ceiling mounting using
industry-standard mounting hardware. See Appendix D on page 37 in this manual for details.

LSR4300 Series monitors are designed to be positioned vertically and not horizontally.
This orientation provides optimum dispersion over the widest listening angle and eliminates
the phase shift that can occur when the relative distances between the woofer, tweeter and
the listening position are altered. Horizontal placement directs high-frequency response
into the work surface causing destructive cancellation resulting in inaccuracies in the
frequency response.
