14 ohm 7” midrange driver

@foeraus

If you are handy with a soldering iron and software, use REW wizard to properly measure the driver impedance.  Otherwise get DATS V3. 

It drives me nuts to see people spending weeks on a problem the right tool could solve immediately.

Talk to Masisound and ask them if they'll measure the DC resistance of an 8535.

PS - Saw another picture saying that the Scanspeak 8535 actually measures 14 Ohms at DC.

No drive vender I know of rates their woofers at DC so that’s probably why you are having the discrepancy.  In all other worlds, the 8535 is an 8 Ohm driver.

Well, that’s weird. Based on the stereophile measurements I’d have guessed it was a Scanspeak 8 ohm unit.  I see it listed in some places as the Scanspeak 8535.
