High Current Comparison
The above chart shows current (vertical axis) versus time (horizontal axis). A bigger fluctuation represents higher current output, and as you can see, Onkyo delivers current well in excess of competitive products. Current grips the speaker cones and controls their movement. More current means the drivers produce sound that more closely matches the original input signal. Less distortion, better control, faster response, more realistic sound.
More Current to Drive Bigger Speakers
A/V receivers with high-current capability can easily drive speakers with larger woofer cones. Without high current flow to control the cone, accuracy is sacrificed. Onkyo A/V receivers produce less distortion when driving larger speakers than comparable products without loss in accuracy.
How is the Sound Different?
High current from the amplifier extends the speaker diaphragm’s range of movement inwards and outwards so it can reproduce a wider spectrum of dynamic information contained within the signal with greater accuracy. This improves your speakers’ ability to reproduce subtle details and textures.
Combining Power and Current for Ultimate Performance
A car with lots of power will not necessarily be a joy to drive. It also has to handle: braking, cornering, and smoothness are as important as outright horsepower. It’s the same with amplifiers. Watts deliver loudness, but it’s current that delivers the detail and dynamism in sound. If your amplifier does not produce enough current, your speakers will not perform to their fullest potential, and you’ll miss out on a fully immersive sonic experience.
