[QUOTE="Buck, post: 8800556, member: 591582"] I think the noise maybe comes from the higher frequency mosfet gate switching to make the power steps with half-bridge output filtering. I think the full bridges are fundamentally cheaper with the way they’re built, because of the lack of need of more parts. They leave off a lot of that filter stuff on the full bridges on the output side. This is what I meant by the pulsations and the power supplies: [ATTACH=full]40560[/ATTACH] There may be fluctuation balance in between the power supplies in the total circuit, which may lead to better production of the waveform (like damping)<-that’s a theory. The load is in between the two power supplies internally. I think the load being surrounded by mosfets in a full bridge can cause the amp to lose control of the sub, if the woofer is moving too much, on lows, for example. The woofer can unload into the power supply with half bridge, and that’s a part of damping factor, in my theory. [/QUOTE]
