The best cube:
A beast from Rockford/Fosgate.
The all new Rockford/Fosgate amplifier T15kW has the most
astonishing cube you have ever seen. As the name implies, it
delivers an amazing 15,000 watts.
Introduced at the 2006 Consumer Electronics show, the
T15kW 15000 watt amplifier uses HT Technology. Unmatched dynamic
power capabilities, ability to drive low impedance loads and
reduce the strain on a vehicle’s electrical system are but a few
of the advantages of HT Technology.
Developed and tested with the PowerCube from AudioGraph, the
design is now ready for the market in record time. “The
amplifier uses a patent pending technology we call hybrid
technology”, says Rockford Lead Engineer Anthony D'Amore.
“Using the PowerCube from AudioGraph, we have managed to design,
test and manufacture this all-new amplifier with its
ground-breaking technology.”
“This is the best example a perfect cube I have ever seen”
says AudioGraph founder and CEO Lars Ohlen. “Over the years we
have tested hundreds of systems, but no amplifier comes even
near to this result”. Lars Ohlen also points out the Class-D
capabilities of the PowerCube 2005 system.
A near-perfect cube: The T15kW amplifier from Rockford/Fosgate
delivers true power at an astonishing rate.
The PowerCube measurements
are presented in a 3D-graph, making it easy to verify your
design’s power capabilities using 20 different load conditions.
“The AudioGraph PowerCube 2005 is
not only producing high quality, unique 3D-measurements of
amplifiers, it is also an integrated part of the development and
production cycle at the world leading audio manufacturers”.
“Our latest system lets you test
all your new audio amplifier constructions, conventional or
Class D.” says AudioGraph founder and CEO Lars Ohlen. “Magazines
in Europe are using our measurements when reviewing amplifiers.
If you are a developer you can use it to verify designs as you
go along – reducing costs and saving time.”

Fig 1: Good example |
Fig 2: Poor power supply |
Fig 3: Current limiting |
In Fig.1, you can find a good example. Regardless of
the load, this amplifier can produce an almost equal voltage
without clipping. Although you'll see some small losses when the
load decreases, this amp will handle any loudspeaker.
In Fig.2, the output voltage is dramatically reduced
into lower impedances. This amp will definitely not handle a
real-world loudspeaker very well.
In Fig.3, the amplifier works into 8, 4 and 2 ohm
resistive loads, but any reactive load will trigger the
protection circuits and shut down the amplifier! This amp is
essentially incapable of driving a real-world loudspeaker.
