We are providing test results performed by us of the VE Audio AB-150.2 2ohm model.

We are using our professional Next-USB System with Level 3 AC/DC 1200A TH HE Sensor for power output measuring and our Level 2 AC/DC 400A Sensor for power input measuring.

We are using our own contracted import company - JFA Eletronicos for regulated 115/220v AC to DC Power Supply adjustable from 12.8-14.4vDC.

We are using Centech Infrared Temperature gun for monitoring ambient and Amplifier temperature.

We are using 8 1,000w Resistive banks mounted to Steel bars for output load and heat dissipation.

We are using SPL-Lab Software v2.6.10 in both Power and RTA mode.

Amplifier rated output-

150w x 2 4Ω 14.4v 1%THD

240w x 2 2Ω 14.4v 1%THD

480w x 1 4Ω 14.4v 1%THD

Our Test Results-

(Because we provide more test data than anyone else, it will be impossible to accurately compare our data with another tester without knowing all of their values as well.)

QoSFRRTAT- ("cause-for-tat")

Quality of Signal Frequency Response Real Time Analyzing Test

This tests the FR amplitude curve by measuring the signal amplitude WITH a fixed load on it that is allowed to receive variables during test such as increase in temperature, etc that would likely happen in real world.

Results-

One thing that greatly sticks out about this amplifier is the higher frequency range exhibits virtually no distortion.

We did several burst tests at 5 and 10KHz with everything maxed out and could not get a distortion reading that is worth even noting.

While this is a full range Class AB amplifier, using it solely for horns, tweeters and super tweeters would make a great product of choice to virtually guarantee a full clean amplification.

Using it for everything else, it has the ability to burst into a higher THD resulting in wider dynamic range but it's only really measurable on max settings. The amplifier tends to stay clean throughout the spectrum as noted in video above.
