Preventing Speaker Damage
GoldenEar BRX speakers are efcient and can be driven to loud listening levels with moderate amplier power.
They are also able to handle the output of very powerful ampliers. To prevent damage to your speakers, please
read all of the following guidelines before hooking them up.
Amplier Distortion — #1 Threat to your New Speakers!
Amplier distortion is the principal cause of speaker damage. When listening at loud levels your amplier 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 ampliers are actually safer – For example: A 40 Watt/channel amplier will
have substantial distortion above 40 Watts. If driven to 50 Watts, this amplier will deliver speaker-damaging
distorted power! But a 100 Watt/channel amplier will have very low distortion below 100 Watts. Therefore, when
the speaker requires 50 Watts, this more powerful amplier will deliver clean power and speaker damage is less
likely to occur. (See your GoldenEar dealer for amplier recommendations.)
Volume Setting
Do not be fooled by the Volume setting of your receiver/preamplier. It only adjusts listening level — it is not
a “power-output” dial. The amount of amplier 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 amplier power than a loud section). With typical material, the rated output power of many receivers/
ampliers 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 ampliers 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 amplier(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 amplier.
There is Actually a Limit!
Even with these safer, more powerful ampliers, 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 amplier can overdrive your
speakers and damage them. And if the amplier 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!
Avoid use of tone controls and loudness controls as they will demand even more power from
an amplifier, lowering the volume at which damage could occur.
