Infinity RS 1b the one with 4 Towers - Recommend?

7 years? wow. Anyway, I used to own it's smaller sibling the RSIIa. IF the EMIMS and EMITS are all working, you are OK. The parts for the EMIMS are NOT available, and individual WORKING EMIMs are worth at least $200 each, the EMITS are worth $100. each. Remember, a bunch of IRS $20,000 to $70,000 systems out there and they WILL pay for EMIMs.
The biggest problem with the EMIMS is the wire tab breaking off. You must repair the wire, no replacement parts. (though i heard someone was making the parts, though Infinity killed them by patent... But somebody in China may be making the inner part for EMIMs anyway..
If parts are available, then your EMIMS are worth $50.
Other than that, the speaker is worth more (if the wood is perfect AND everything works)than $3K. You still have a desirable system.
You need LOTS of amp for that.
The usual joke is: it is worthless, can I come over and take it off your hands as a 'favor'. LOL

Still great speakers,if well preserved.Sid Marks of TAS fame(he wrote the Mercury and RCA LP column for years)still has this speaker as his main set up.I've heard them at his place,like a zillion times.

I had them years ago,and wonder why I got rid of them.

SUPERB....and don't doubt that for a minute!Actually,in today's market,and poor economy, these designs would sell for a small fortune.

Consider yourself lucky-:)

Good luck

Apogee Acoustics in Australia IS making a replacement for the EMIM.

Yes, fine speakers but rot will set in and cones will also go bad. Dump them while you can. Much better stuff out there.

My RS1-B's are about 28 yrs old. I originally bought the first pair of RS-1's from Lyric. Then I had them moded to the 1A's. The Arnie Nudel visited me and convinced me to upgrade to the B's. I dit that but also did some extra mods (somewhat similar to Sid's but not that extensive).

When I would visit shows or visit a friends home to hear their system I always felt that, as aged my system is) it still represented a great illusion of thew sound I appreciated.

My EMIMS have all been replace but my EMITS and woofers are all original.

A truly GREAT system (Sid's is better).

P.S. Good to see you back, Mark!
