Infinity RS-II vs. Klipsch RP-5

The pictures of the 'b' for the RSIb ($12,000) had dark 'graphite' cones on the woofers.
The 'a' had clear poly cones on the woofers.
I do not know for certain they also did the graphite woofer cones for the RSIIb.
But I 'think' they did.
A lot fewer 'b's were sold than 'a' in the Infinity RSII sets.
The visible look of the woofer cone is the only thing I know of which one could tell by looking.

I actually do not know for certain they also changed the woofers for the RSIIb as the RSIIb price did not go up a lot, as the RSIb did.
The RSIb jumped from $7,000(a)to like $12,000.(b)
The RSI speakers were with the separate 4 woofer column sets. and 9 EMIMs in columns.
So they were a lot more expensive than the RSII

The EMIM change was very minor. Slightly stronger magnets only. No crossover of cabinet changes. Nor any change in the EQ box.

Again, very helpful! Thanks!!

I should have mentioned earlier - even though I haven't seen the speakers in person yet to apply all the information you provided, I do know when the guy bought these in the early 80's they retailed for $2,000 a pair.

With that price in mind, which model would you speculate them to be? If you think you may know, what do you think they would be worth in today's market? (just a ball park idea)

Thanks again Elizabeth!

I just re-read your original answer with price estimates. Considering you said the RSII went for $1,500 and this guy got them on sale from $2000 down to a $1000 for the pair, I think that's the answer - RSII

To expand on my question about their value today - he also had the subs professionally replaced in the last year. Do you have any thoughts on their value IF they were replaced with original equipment versus cones from some other company?

Thank you again for your input!

The change in woofers does not change the value of the speaker, used. In fact IMO they are worth less due to the most likely negative change in the sound balance.
It is hard to find replacement drivers with the same characteristics of the originals.
Why don't you just ASK the seller if the midrange are three 3" cones?
Then you would know they are the RSII, and not worth much.
Like I wrote, the RSII are really not great speakers, they look big, but have little resale value $400 tops is all they are worth. And even less with replacement woofers.

Thanks!!
