[QUOTE="Buck, post: 8914653, member: 591582"] 100% disagree that 100 damping factor is enough, at least for 1 ohm systems. I've noticed a significant difference from literally testing myself where the amp was the only change, where an amp with a like 100-150 damping factor did not play as low as an amp with a 250-300 damping factor by 2,3,4 hz (under ported box tuning). I tested this with bass tones. This is why I maybe come across strong on this subject bc I tested this some and installed a lot of amps and boxes and systems and paid attention to specifically the amps. So this: "The damping factor is the ratio of a loudspeaker's impedance to the amplifier's output impedance, which helps control the speaker's cone motion and reduce unwanted movement caused by back electromotive force (back EMF). A higher damping factor allows the amplifier to better manage the speaker's response, especially at low frequencies, leading to tighter and more accurate sound." [URL unfurl="true"]https://en.wikipedia.org/wiki/Counter-electromotive_force[/URL] I once designed a box for 5 15 inch woofers each of which had a 45 mm one way X max, and a 4" VC with 800 MMS rated for 4500 W RMS. So that's 22500w rms. It wasn't ever built but just giving an extreme example- I can give other examples. I had to take amps into account with some designs. That system playing low notes where it's hitting high X max and shifting notes, there's a lot of back emf with that. The amp has to keep those big, super heavy coils under control under extreme xmax, and that would be an example of where 100 damping factor is going to hurt you. I can't imagine it wouldn't vs having idk 300-400-500 damping. [/QUOTE]
