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

I have only heard the irs reference speakers modded by ps audio at the ps audio factory.

Their listening room was on the small side for these speakers. If you have a large listening room, they could keep up with today’s flagship speakers or beat many of them.

Paul McGowan’s new Aspen FR30 ain’t beating that infinity, no matter what his sales pitch is.

Just in case you want to buy a pair of IRS speakers (IRSV fully refurbished and updated): https://www.youtube.com/watch?v=oXU9xIgv_DI

Interesting video by Paul McGowan of PS Audio.

I bought Brooks Berdan’s personal pair of RS-1b’s in the late-90’s for $2,000, and sold them back to him in 2008.

Anyone contemplating buying any of the Infinity’s that contain the EMIT/EMIM drivers should be prepared to have some restoration done. Paul McGowan spent a LOT of money fixing his IRS’es.

From one who’s been there, before you buy a pair of RS-1b’s, give a listen to the Eminent Technology LFT-8b (and/or -8c). Imo a better loudspeaker employing planar-magnetic drivers, one whose drivers don’t fail. Infinity's were not built to high end standards.

I'm with @cleeds I own and enjoy my IRS Beta.  Been around many other great speakers and only kept my Beta and on my secondary system my Aerial 8b.

Replaced the Solen caps all else is in-spec! on the crossovers.

as an experiment I am getting spare EMIM's rebuilt with very modern diaphragms (not current copies of the originals).

I have purchased AVA replacement diaphragms just in case for the future and to sponsor AVA's dedication to the brand.

What replacement diaphragm are you using
