8 Ohm load

With jumpers removed from RTi-A9 speakers, do both binding posts present a nominal 8 ohm load? Saw an earlier thread and imo opinion no clear answer was given. This is yes or no. Not looking to get flamed for this question. I will be using 2 Luxman M-120A in BTL for 300 watts on the woofer section and a Luxman M-02 in stereo for 150 watts to the mid/tweeter. Thanks.

Did Stereophile ever review these loudspeakers? If so, there should be about as accurate & meaningful of an impedance curve in the quantitative measurements section of the review as you'll ever find anyplace (including from the manufacturer) for this particular model.
Impedance of any loudpeaker using "normal" (cone or dome) dynamic drivers and passive crossovers will never be well represented by a single number. Not no way, not no how (to quote the guard, IIRC, in The Wizard of Oz).
So -- "maybe" may be even overstating things a bit!

Thanks for the input F1nut.
You're welcome. It was the correct answer.With jumpers removed from RTi-A9 speakers, do both binding posts present a nominal 8 ohm load?

What you really need to concern yourself with is having a way to match the gain of the different amplifiers.

I suppose the question is because the M120a would be run bridged to mono and therefore be unstable into lower than 8 ohm loads?
If so, I’d try a different arrangement anyway because I don’t like the drawbacks of running amps that way. -
Just went through this. Most likely they are not and you would have to do your best at gain matching the highs and lows. Not easy
Better off getting the power you want out of a mono block per tower. -

lol!
Believe it or not that did not cross my mind until you mentioned it, although it seemed that I had an ulterior motive -
I would think both posts should be nominal 8 oms (but if you blow something who am I and why are you taking my free advice).
If this speaker was wired for one input they wouldn't design it so the tweeters was at one ohm and the woofers at 16. That does not average to 8. The lower resistance circuit would get most of the power and fry itself.
For a reality check test the resistance at both posts with a multimeter. It won't read 8 ohms (that is inductance when playing) but it should read around 6 ohms.
