OVERVIEW
The Epos ELS Sub is an active loudspeaker. In other words, that
means that it has an in-built power amplifier to boost the signal
level. Therefore, there is no need for an external power amplifier to
drive it. In addition, the ELS Sub has a complex filter circuit which
boosts sub-sonic frequencies and is adjustable to allow it to be
matched to different room sizes, shapes and user requirements.
The rear panel controls provide a range of adjustment for this
purpose.
The ELS Sub is designed to extend the low frequency response of
both 2 channel and multi-channel systems, which demand very
different tonal balance. This is described later, but control
adjustment and placement in the listening room is important, so
please read these instructions carefully for best results.
QUALITY
The ELS Sub has a massive and powerful 10” loudspeaker driver,
with enough magnet strength and voice coil size to handle very
high power levels for long periods without distress. Its cone
diaphragm is very stiff to keep distortion and colouration to a
minimum. The rubber suspension surround is smaller than normal
and quite stiff, which also helps to reduce distortion and low
frequency over-hang. In short it has been designed to be more
appropriate for a two channel bass unit than a conventional sub-
woofer.
To further boost the fidelity of the ELS Sub, it has a very stiff cabinet
with extensive internal bracing, which is rarely found in
conventional subwoofers and has a completely separate section
at the back of the cabinet to house the amplifier, which is more
normally found in professional speakers and not found in
conventional subwoofer at any price.
To further improve the sound quality Epos does not use port tuning
to achieve increased bass extension, which avoids 'chuffing' air
turbulence noises interfering with the fidelity of the speaker.
In short, the ELS Sub is very unusual and can be used to good effect
to extend the frequency response of a stereo system of any quality
or price.
INSTALLATION AND SETUP
Having established which power cord to use, select the correct
mains voltage for your region with the selector switch on the back
panel. (If in doubt, please read Page 2 again or ask your supplying
dealer for advice).
If neither of the two cords are correct for your
mains supply socket, do not proceed until you have contacted
your dealer for advice or assistance.
Positioning the subwoofer is important if the best results are to be
achieved. Place the sub where it can be connected easily to the
mains power supply and to the output of the receiver or amplifier
used for the rest of your system. Needless to say, this would
normally be at the front of the system, but be prepared to move it
around the room to gain the best results.
Find the best position before mounting it on its spiked feet. Once
this is done, screw the feet which are supplied in the accessory pack
into the screw inserts in the bottom of the cabinet and adjust the
height of each to make it level and tighten the locking nuts to secure
them and prevent rattling. Allow room to make adjustments and to
see the controls. The mains supply can be left connected as it has a
low current standby condition which is enabled when no signal is
present for a short while.
