JL AUDIO ZR800-CW 7
MEDIUM GRAY MINIMUM:
From a reliability standpoint, this zone
represents a very comfortable operating
power range for each driver. This level
of power will not stress the woofer but
will not extract all of its performance
potential, either.
Use of less than the minimum power
level will not damage the woofer, but may
result in unsatisfactory performance.
LIGHT GRAY OPTIMUM:
This zone represents the best
compromise between long-term
reliability, high-output and low-distortion
performance. This power level is lower
than the woofer’s continuous power rating
(as published in its specifications), but
you will still be taking advantage of the
woofer’s, low-distortion performance
range without undue risk of failure.
DARK GRAY MAXIMUM:
Slightly more SPL will be gained by
pushing the power into this zone, but
typically not more than 2dB, compared to
the light gray zone. The subwoofer driver
is designed to operate safely up to this
power range, but not beyond. Operate
with caution.
BLACK WARRANTY VOID:
We do not recommend operating
woofers at this level of power. In this
zone, there is a very high probability
that the driver will fail due to excessive
heat and/or mechanical stress.
Drivers operated at these levels of
power are NOT covered under warranty.
RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE COMPONENT WOOFER:
When designing systems with our drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities.
The power levels listed in the above chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power
without drastically overdriving the amplifier(s). Make sure you factor system impedance and the total number of subwoofers into your calculations. Adhering to these
power recommendations will result in systems that are both reliable and enjoyable.
