BI-WIRING/BI-AMPING
If bi-wiring or bi-amping is desired, remove the two terminal jumpers
and connect speaker wires appropriately to the terminals marked
HF (high frequencies) and LF (low frequencies).
The purpose of bi-wiring is to reduce interaction between
woofer and midrange and/or tweeter. Separate cables are
connected to the low requency (LF) terminal and the high
frequency (HF) terminal. Both cables are connected to the
same terminal on the receiver/amplier.
The highest possible performance is obtained by using
separate ampliers for LF and HF. Identical ampliers can
must be observed:
- All ampliers should be phase coherent, either phase or
non-phase inverting, and have identical voltage gain.
- Each amplier for LF, and each amplier for HF, must
be identical.
INSTALLATION
RECOMMENDED AMPLIFIER POWER
To get the best performance from your ES-HT900-LCR-6 speaker, we recommend powering it with an amplier or receiver
SPEAKER WIRE
To connect your ES-HT900-LCR-6 speaker to your amplier, high quality 12 to 16 gauge stranded speaker wire is
recommended. The wire may be connected directly to the speaker’s ve-way binding posts or terminated with
either spade lugs or banana plugs.
SPEAKER PLACEMENT
For Left, Right and Center applications, the ES-HT900-LCR-6 should be placed with the ribbon tweeter at ear height
(about 40 to 50 inches from the oor). This positioning will provide the clearest sound and best dialog intelligibility.
For Center channel applications, place the ES-HT900-LCR-6 directly above or below the screen or behind it
in installations where a perforated screen is used.
For Left and Right speaker applications, place the speakers on either side of the screen at equal distances from the center
of the screen. Ideally, the two speakers should be spaced 6 to 12 feet apart. Left and Right speakers should also be equal
distance (about 8 to 20 feet) away from the center of the primary listening position. For best results, turn the left speaker
upside down so the tweeters on both speakers are on the outside, facing away from the screen.
When used as a Surround or Surround Back speaker, the ES-HT900-LCR-6 should be placed to the side or rear of the listening
area respectively, at about 6 feet above the oor. When used as a surround, the LCR should typically be placed as far from
INSTALLING AND REMOVING THE GRILL
To remove the grille, start in one top corner and gently pull the grille frame away from the front bae of the speaker.
Repeat process in remaining three corners. To install the grille, start in one top corner and gently press the grille frame
in around the front bae, pushing it in at each of the remaining three recessed holes.
ADJUSTMENTS
Once installed and connected to the home theater system, the ES-HT900-LCR-6 can be further tweaked by setting the
Screen EQ and Boundary Compensation switches located on the front of the speaker. Both of these settings are highly
dependent on the installation, location and theater arrangement. There is not one “right” way to set these adjustments.
Typically, what sounds the best to the listener is “right” for that installation.
When the Screen EQ switch is engaged, the high frequency level (those above 3kHz) is increased by 3dB. This can help
compensate for heavy grille cloth, location behind a perforated lm screen, or other installation compromises.
Engaging the Boundary Compensation switch will decrease frequencies below 80Hz by 3dB. Some cabinet installations
may increase the perceived loudness in the low frequency range, which can result in “boomy” or “muddy” bass. Turn Bound-
ary Compensation “on” if the bass or lower mid bass seems “muddy”.
TWEETER ROTATION
For horizontal installations, the tweeter should be rotated 90 degrees to maintain its optimum dispersion pattern. In order
to do this, the tweeter and the front-mounted port tube has to switch locations. Follow the instructions below closely to
avoid damaging any parts of the speaker.
To rotate the tweeter, follow these steps:
1. Lay the speaker on its back (drivers facing up) on
a solid surface.
2. Remove the 6 screws on the front of the ribbon
and the 6 screws on the front of the port tube
(as shown in the illustration).
3. Carefully remove the port tube from the box by
gently lifting it upward.
4. Reach into the hole that held the port tube and
gently push the tweeter up. Using your other hand,
hold the tweeter slightly above the cabinet. You
may now disconnect the wires from the tweeter.
5. Reroute the tweeter wires through the opening
that you are moving the tweeter to, and
reconnect to the tweeter.
6. Carefully seat the tweeter in the opening,
ensuring that the gasket material is
placed properly in the recess between
the tweeter and the bae.
7. Lower the port tube into the hole that initially held
tweeter, ensuring that the gasket material is placed
properly in the recess between the port and the bae.
8. Tighten the 6 screws for the tweeter and 6 screws
for the port tube. Be careful not to over-tighten
as this may crack the tweeter ange or port tube.
19. You can also rotate the Screen EQ/Boundary
Compensation plate by removing the 4 screws.

performance and proper high-frequency dispersion.
