longevity.

Dear Valued Customer,

WARNING: These products are
capable of generating high
sound pressure levels. You
should exercise caution when
operating these speakers. Long

term exposures to high levels of
sound pressure will cause permanent damage
to your hearing. Sound pressure levels
exceeding 85dB can be dangerous with
constant exposure, set your audio system to a
comfortable loudness level. Earthquake
Sound Corporation does not assume liability
for damages resulting from the direct use of
Earthquake speakers , and urges users to play
volume at moderate levels.

ECS6D & ECS8D

The Edgeless In-Ceiling Dual speakers are designed for use in limited/small
spaces like bathrooms, kitchens, corridors, etc... They feature dual tweeters
and dual woofer voice coils (2 speakers in 1): one ECSD is capable of
reproducing a stereo signal; thus eliminating the need to use two speakers.

The Edgeless In-Ceiling speakers are designed for use in any space like
bedrooms, living rooms, kitchens, etc... Each features a single 1” Neo tweeter
and a long excursion woofer. The ECS seamlessly blend into surrounding as
they provide a lifetime of durability and high-end performance.

The ECS6D is equipped with two (2) switches: the Bipole/Dipole switch and the
Surround/DVC switch. The two switches work independently, they are used to

customize the ECS6D performance for different applications.
In Dipole mode, the speaker is in STEREO mode (2 speakers in 1). The two

terminals are totally independent (2 separate inputs, using both terminals).
Each terminal has an impedance of 8-Ohm. The speaker can be set in Surround
or in DVC mode depending on the listener preferences. In Bipole mode, the
speaker is in MONO mode. The two terminals are internally connected in
parallel (1 input needed, using only one terminal). The total speaker impedance
is 4-Ohm. Again, he speaker can be set in Surround or in DVC mode depending
on the listener preferences.

In DVC mode, the speaker exhibits higher level of details & separation between
L & R channels. The Surround mode gives the speaker response more
surround feeling, deeper warmer bass & more blending between L & R
channels.

Simply tighten the screws by hand using a
screwdriver to prevent the mounting ears
from snapping. Some resistance may occur
the first few turns of the screw as it makes its
path through the plastic.

Easy Installation Steps

1

Cut the hole:
using the provided
cut out template

2

Wire the speaker:
using the non-obtrusive
spring-loaded speaker
terminals

3

Mount the speaker:
by utilizing the
Turn-N-Lock™
installation mechanisms

Placement Considerations

Speaker Placement

The ECS Edgeless In-Ceiling Speakers are designed to be flush mounted in
walls or ceilings. For optimal acoustical performance, simply follow these
guidelines:

1. Place speakers at an equal distance (left/right) from listener.

2. Speakers must be spaced at a 40 - 60° angle from listener (Figure 1).

3. Aim tweeter towards the listener’s ear when in listening position.

Grille Painting Guidelines
The ECS Edgeless In-Ceilingl Speaker grilles are paintable and can accept

virtually any type of paint. We strongly recommend the following:

1. Remove the grilles from the speakers prior to painting them.

2. Thin the paint prior to application, if needed. Spray and roller paint
applications typically provide the best results. Note that you may need to
apply multiple thin layers of paint to achieve the desired shade without
losing sound quality due to clogging of the grilles.

3. Let the painted grilles fully dry before mounting them back on the
speakers.
