Infinity RS 1B - How does the 'old dream speaker' compare to today's speakers?

I mean the 'big' system Infinity Reference Standard IRS. 

Sounds like the IRS are still competing well with modern speakers. I would have guessed that they had fallen behind due to decades in material (and electronics) development). 

What I WANTED to ask about was the BIG Infinity. Checked today and it is the IRS, with full length EMIT for mid and high. Vs the Rs-1b with less midrange EMITS and only 3 tweeter EMITs (plus one in the back). 

ervikingo: I heard a pair of RS-1B in a local store. Disappointing. But turns out there was all sorts of things wrong with that pair/setup. Some of the mids NOTICEABLY rattled, not sure if the crossover was used properly, etc. They were cheap, but even at the low price, not 'worth it' IMO. Must have been THAT pair, because otherwise the RS=1B cannot be that bad (maybe not on the level of the IRS). 

mgattmch thanks again for the link. Watched it again. Interestingly, the "Mike from Brighton" is probably in the same Brighton that I live!
