Preventing Speaker Damage
GoldenEar Technology SuperCinema 3D Array speakers are efficient and can be driven to loud listening levels
with moderate amplifier power. They are also able to handle the output of very powerful amplifiers. To prevent
damage to your speakers, please read all of the following guidelines before hooking them up. Please also note,
that the SuperCinema 3D Array speaker is designed to be high-passed and used with a subwoofer. Attempting
to play them full range (no high-pass) at high volumes can damage the speaker.
Amplifier Distortion — #1 Threat to your New Speakers!
Amplifier distortion is the principal cause of speaker damage. When listening at loud levels your amplifier may run
out of clean power. It will then begin to produce speaker-damaging distorted power. This will damage any brand of
speaker very quickly! More powerful amplifiers are actually safer – For example: A 40 Watt/channel amplifier
will have substantial distortion above 40 Watts. If driven to 50 Watts, this amplifier will deliver speaker-damaging
distorted power! But a 100 Watt/channel amplifier will have very low distortion below 100 Watts. Therefore, when the
speaker requires 50 Watts, this more powerful amplifier will deliver clean power and speaker damage is less likely to
occur. (See your GoldenEar Technology dealer for amplifier recommendations.)
Volume Setting
Do not be fooled by the Volume setting of your receiver/preamplifier. It only adjusts listening level — it is not
a “power-output” dial. The amount of amplifier power actually used at a given Volume setting depends solely
on the nature of the source material you are listening to (at a given Volume setting a quiet section of music will
use less amplifier power than a loud section). With typical material, the rated output power of many receivers/
amplifiers is often reached when the Volume is set to around -10dB, or between the “11” and “1 o’clock”
settings with an analog control (with bass/ treble and loudness controls not used — otherwise rated power may
be reached at even lower Volume settings). Remember, all amplifiers produce distortion when operated beyond
their rated output power. The resulting distortion will damage all speakers! If you listen at loud levels, be careful to
listen for the point of audible distortion — if the speakers begin to sound distressed, turn the Volume down or your
speakers and/or amplifier(s) will be damaged! This type of damage constitutes abuse and is not covered by the
warranty. If louder volumes are desired, consider a more powerful amplifier.
There is Actually a Limit!
Even with these safer, more powerful amplifiers, there is a point at which you could have more power than the
speaker can handle. At that point you will overpower the speaker and damage it. At loud levels do not increase
bass/treble controls from zero and ensure that all loudness/contour/bass EQ buttons are off (otherwise rated
output power will be reached at even lower volume control settings).

USE AN APPROPRIATE AMPLIFIER. At high volumes a very powerful amplifier can overdrive your
speakers and damage them. And if the amplifier is not powerful enough, it can produce distortion
that can easily damage your speaker. (Consult your dealer for assistance.)
DON’T BE FOOLED BY YOUR RECEIVER’S VOLUME CONTROL. It only adjusts how loud, it is not an
indication of power output. If your speakers begin to sound harsh or grating or if you hear other forms
of distortion, turn down the volume immediately!
PROPER SETUP IS THE KEY. Please Note: Your SuperCinema 3D Array speakers are designed to
be used with a subwoofer and with a high-pass crossover (“SMALL” setting on an A/V receiver).
Also, avoid use of tone controls and loudness controls as they will demand even more power from
an amplifier.
