Power 1 500 Watt Class-bd Konstantkraftforsterker

The Constant Power feature really shines when I’ve got the gain set low on a 4-ohm load—it still hits harder than my old amp did at the same settings. Frequency response feels tight and punchy, not muddy at all. No complaints so far.

First noticed the difference on a 2-ohm load—this thing just doesn’t sag like my old amp. The Constant Power tech really does squeeze out that extra 25%, and the bass stays tight even when I crank it for hours.

I was skeptical about the "constant power" claim, but driving a 2-ohm load it genuinely stays punchy where my old amp sagged. The frequency response optimization makes a real difference for clean mid-bass, not just loud noise.
