Xmax! (1 Viewer)

[Brian Bunge]

OK, guys! I know that you can get a general idea of Xmax from the voice coil length and the air gap length but I don't have my copy of the LDC handy. Can someone post the little formula?
Thanks,
Brian

I believe peak Xmax = (absolute value of [voic-coil length] - [airgap length]) / 2

Issac,
OK, so if VC length=32mm and air gap=8mm then Xmax would be 12mm. I assume this is for 1 way since we divide by 2, correct?

Brian,
So with a coil length of 32 and a gap of 8, would that be (32-8)/2 or 32 -(8/2)? I'm guessing it's the first or 12mm, right? So if the Monitor Audio FB 212 uses 2 of these in a push/pull isobarik config. in a ~1.9 ft3 vented enclosure with a 360 watt amp, how do you think it might compare to the single SV-12 inside the same size sealed TitanII with 250 watt amp?
Anybody?
