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

@cleeds: While I heard the IRS once (Mike Kay of Lyric Audio brought his pair to the Stereophile Show in L.A. one year), the highest-level model I have lived with was the RS-1b (my first Infinity’s were the company’s entry-level speaker---the Model 1001, bought new in 1971. I lusted for the Model 2000A---with it’s RTR ESL tweeters, but didn’t have the $). If you find the Beta to be built to a standard you consider high end, I’ll take your word for it!

The planar-magnetic panels of the RS-1b are attached to their bases with mere wood screws, and the panels sway fore-and-aft with the slightest breeze. Paul McGowen has given his opinion of the woofers that came in the IRS bass towers (about the same quality as the woofers found in Tekton loudspeakers), and of the quality of the outboard crossovers.

One listen to the ET LFT-8b was all it took for me to decide to ditch the RS-1b’s.

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). 

@kraftwerkturbo have listened to the IRS V, the 1b, other models and my Beta.

The V have a huge stage and are fantastic on instrumental and vocals, the 1b (IMHO) are nowhere near the V nor the Beta.  But Im biased,

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!
