Some examples of cubes - real-live measurements from real-live
First we look at three examples which describes three basic shapes of the
PowerCube measurements, and then we look at three well known brands... and
we're not disclosing any names except one...
The perfect amplifier doesn't care about the load - it's a pure voltage
generator - so the measurement of a theoretically ideal amp would produce a
cube, hence the name "PowerCube".
In popular price ranges you can't really expect to find an amplifier that
will produce a perfect cube, you can see a good example in the last cube on
this page - a very well designed two channel amp from Rotel. Of course, good
Class D amplifiers do exist, just as with any other topology, but you need a
PowerCube system to find them!
If you pay top dollars, you can come very close to a perfect cube.
This is the best cube ever. The Rockford Fosgate T15kW amplifier
uses HT Technology which gives the amplifier unmatched dynamic power
The cube is near perfect, but expect to pay USD 20,000!
Here are some more examples:
