Using KEMPER Kone with PROFILER PowerHead or PowerRack

If you are afraid of damaging your KEMPER Kone speaker with the built-in 600W power amp of the PROFILER, then
use the Wattage Meter to monitor exactly how much power is being delivered.
Speaker damage isn't caused by receiving too much peak level, but by the accumulation of too much heat over time.
Think of a traditional light bulb: When you switch it on, it takes a moment to reach full brightness. When you switch it
off, it will dim slowly even though the current is cut immediately. Due to this time lag, it takes one or two seconds of
overpowering a light bulb before it breaks. The same applies to the coils of your speakers.
The Wattage Meter takes account of this time lag and simulates the accumulated heat in your voice coil measured in
watts. It is a unique tool that allows you to get a feel for the kind of volume you should expect for a given number of
watts. You might be surprised just how loud a few watts can be, and how much signal is created before you reach
the 200 watts maximum power load of a single KEMPER Kone.
A few rules of thumb:
•
The maximum wattage of the power amp is not a measure of permanent load on your speaker coils. It depends on
how loud you play. A 600 hp car will not use more horsepower than a 100 hp car while you cruise through town —
more likely, it will be about 15 hp.
•
Bass frequencies will put much more load on your speakers than high frequencies. Palm mutes create lots of bass.
•
The Bass Boost feature of the KEMPER Kone mode has the potential of doubling the wattage load! Deactivate it, if
the wattage rises too high.
Cabinets with an open back will acoustically reduce the bass frequencies — this means wattage which the power
•
amp delivers, and the speakers still have to process, but you cannot hear it and therefore won't realize.
•
If you are running two KEMPER Kones in series, either in a 2x12 cabinet or by daisy-chaining two KEMPER
Kabinets, you can divide the wattage value by four, thus never exceeding the maximum load. (Explanation: two
KEMPER Kones in series will double the impedance, thus lowering the current and distributing the heat between two
coils).
•
If you are running four KEMPER Kones in a 4x12 cabinet, you can also divide the wattage value by four, thus never
exceeding the maximum load. (Explanation: four KEMPER Kones in the typical parallel/serial configuration will not
lower the current but distribute the heat among four coils).
