[QUOTE="Buck, post: 8798972, member: 591582"] It’s not as dramatic as you’re making it, lol. Why don’t you go de-pump your nuts a tad. Idk how it’s not a factor, when it seems like many more expensive amps have higher damping factors than less expensive amps. What’s the difference in damping factor between Sundown’s SIA vs a Sundown Salt series? Idk wtf you’re talking about like I’m bowing down before the God of damping or something. Voltage tries to go back into the amp from sub movement generating electricity, or trying to. It’s not just an “output” but an input, as well. AC is what powers subs, so both speaker terminals on the amps also flip, and the sub can overcharge that wire, trying to send electricity back into the amp. How the amp deals with the sub’s electrical changes is the damping factor. I guess the (relative) damping factor of boxes doesn’t matter, either. ‘Damping Factor: This is a quantity which defines how quickly the amplifier can stop a reproduced frequency such as a bass note. The higher the damping factor, the better the amp will control the woofer and help reduce overhang distortion (again to a point). The damping factor of an amplifier is mostly dependent on the output impedance of the power amplifier and the ability of the power supply which feeds the power amp.’ [URL unfurl="true"]https://www.audioholics.com/frequent-questions/what-is-slew-rate-and-damping-factor[/URL] ‘…and the ability of the power supply which feeds the power amp.’ ^^^That‘s why full bridges tend to have lower damping factors than half bridges.
