This is the alpha 6c, supposed to be sort of a 4ohm version of the alpha6.

Anybody other than me notice something weird about the impedance curve? The lowest spot on this chart is between 8 and 9 ohms. Hoping this is a mis-print. I could use one or two of these in an oddball cab or 2 I have, 4ohm woofers, series cable, etc.
