Getting Started; Unpacking; Placement - JBL LSR Owner's Manual

Section 2. - GETTING STARTED

2.1 Unpacking:

When removing the systems from their packaging, it is important not to grasp the units from the
front. This is identified as the carbon fiber baffle and can easily be distinguished by the silver stripe. Because
the high frequency device is located near the top of the cabinet on the front, a stray hand or finger can cause
damage.
An easy way to safely unpack your monitors is to open the top of the box, keep the cardboard filler
piece on, and roll the box upside down. The box can then be slipped off. This also works in reverse for repack-
ing the units to take them to the next session.

2.2 Placement:

The design of the LSR systems lend themselves to a wide variety of placement options. Covered here is
a typical stereo setup for near to mid field monitoring. A deeper discussion of multi-channel sound setup is
available from JBL in Tech Note Volume 3, Number 3.
Listening Distance: By evaluating a broad cross-section of studio environments, it was determined
that the common listening position at recording consoles is generally 1 to 1.5 meters (3 to 5 feet) for near field
applications. For mid-field applications, 2 to 3 meters is more likely. The real key to successful placement is to
form an equilateral triangle between the monitors and the prime listening position. As shown below, the
distance between the monitors and the distance between each monitor and the center of the listener's head are
equivalent.
Vertical vs. Horizontal Placement: The LSR28P near field is designed to be positioned vertically.
This orientation eliminates the phase shifts that occur when the relative distances between the woofer, tweeter
and the listening position change.
