nominal imp. of .7ohm and 1ohm coils, mixing ohm's

2 questions

1. what is the nominal imp. of a 1ohm coil and a .7ohm coil?

2. what happens when you connect 2 diff imp. subs together in series-parallel?

example, say i connect 2 re mt's in series-parallel, and 1 is D1ohm and the other is D .7ohm, will one just get louder than the other, or will they not work?

Your nominal impedance is the just that. So say it's a "4ohm" driver, that's the nominal impedance. Then you have the Re for that, which would be in the ballpark of 3.something. For a "2ohm" it should be 1.something, etc...

If you wire two drivers in parallel and one has a lower Re, that one will draw more current. Generally not a good idea, but between a .7 and 1 ohm driver, I couldn't say how great the difference would be. You get the idea though.

Is that what you got for a reading with a DMM, .7 and 1 ohm respectively?

Yea, both of my mt's are d1 but one sub reads 1.1 and 1.2 and the other sub reads 1.2 and 1.4 before meter rise of .4

Chalk it up to tolerances, I would treat those as the same.
