Bottom Line:   
These are truly great speakers that still be had for a reasonable price on the used market. Most negative comments relate to the low mid frequencies. The key to getting the complete "sweetness" out of these (as with many great vintage 4 ohm speakers like the AR3a or OHM model 1) is good clean current. These will simply not sound great with most combo tuner/amps most of which are generally do not mate well with high power 4 ohm speakers. I would say a minimum of 100 WPC into 4 ohms is needed. Folks not impressed with the mid may be used to or prefer a more unbalanced colored (on the bright side) mid. Definitely east coast sound. The detail is there if set up properly. LF base frequency can be extended a bit lower without affecting detail with several more ounces of damping at the top of the cabinet. The mid can also be tuned by adding or removing a couple of ounces of damping or changing density of damping material. They are a lot of fun to play with even though they are wonderful in stock form.

I have had my RSM speakers for 30 years. The salesman stupidly sold them to me for the same price as a pair of Swedish Research set and later got fired. I have had a protection system fitted to the tweeters due to my then cheap Yamaha Amplifier tearing them up. Here in Australia I have not heard any home Audio system speakers come close to the power & crispness of these gems.Every few years I update my amp and such but never the speakers. They are so good you can hear the snap of a drummers stick during a live concert, well almost.

I have owned a set of infinity reference studio monitor speakers since 1980 (35 years cost $1,000 back then) and they still work very well - however I have had the woofers re-rolled and I replaced the tweeters a while back with "add-on" stand-alone tandy tweeters via parallel connection with the incoming audio signal (the tweeters have their own built in high pass filters) - overall very satisfied with their performance and the sealed speaker box permits excellent bass quality - I expect them to outlive me!

Bottom Line:   
Have owned the Infinity RSM floor speakers since 1984. I got them at a sale for around $119 each. I am about to replace the surrounds again. They are not bad speakers, but not the best by any stretch. The tweeters and 12" woofers are fine. The problem is with the midrange drivers. They have a high compliance, and can take a fair amount of power. However, these midrange drivers are not clean sounding. They lack presence. This is the reason Infinity went to the midrange dome driver. It had a cleaner sound. Because of the rather rubbery compliance and loading on these midrange drivers, they are rather slow. This might be okay for a woofer, but a midrange needs to be a lot faster responding. For this reason, I cannot recommend these. If you can replace the midrange for a cleaner sounding driver, then these might be good speakers.

Bottom Line:   
Running off a clean high power older Technics class A+ amp (0.007%distortion, yes 0.007%, and 90W RMS/channel) and older SONY high-end and ADC components, these sound amazing.

They are better than almost anything now, and they're twenty years old. One refoaming job (i did it personally, keep existing fabric cooling-system dust caps if possible, NEWFOAM has original level stuff) and blowing one tweeter with an improper fuse (just buy a new diaphragm foil, not the whole tweeter) is all the maintenance in those twenty happy years.

The EMITs (Electro-Magnetic-Induction Tweeter, uses extreme high static voltage through planar diaphragm, like SENNHEISER's $12,000 headphones) cast the most lifelike, open, bright soundstage i've ever heard in the industries much neglectid highs. But without sounding overly bright, and no metallic pings, because of the 0.002 inch thickness of the resin/mylar diaphragm.

Midrange is breathy, natural, and extremely good at soundstaging. A very overbuilt mid-driver, cast aluminum frame, magnet is actually larger than the speaker itself! Huge spider for a mid also.

Bass is tight, extremely detailed due to accoustic suspension cabinet and if you really want to make walls move visibly, then play a bass test track and watch these large, pure low resonance polypropylene woofers do their biding.

The high sound quality doesn't compromise effiency (i diasagree with the previous, and with only 4ohm impedance, they're easy to drive with a good amp or receiver) or powerhandling. Each of these speakers has capacity of over 250 W RMS and over 500 peak!

They weigh in at fifty pounds each. Beefy for their relatively small size (27h, 15w, 11d) compared to the modern age of towers. but their squat design has huge volume and less surface area ie: less surface to resonate.

Beautiful thick natural oak veneer, and classic look.

I want another set for to create a 4 point high level music system!!
