Infinity RS1B ? Buy or runaway


I have an opportunity to buy a set of RS1B in excellent condition. They have been well taken care of and are very close to home. Years ago at a Stereophile show, I heard them, wow! The sound and their presence were fantastic! My fear is that like a lot of other things I look back on and lust after look ALOT greater in my memory than they actually perform. Given my current set up and room, I wanted to get some opinions about buying. Or will I be disappointed, maybe due to equipment or the room limitations? I don't think I would get rid of the Apogees unless the RS1B's surpass them in sound quality. Very nervous laying out over 4k for something that won't move quickly if I end up not enjoying them.
My room dimensions are 13' 9" X 25' (Converted garage)
All equipment is located on the front (13' 9") wall with an entry door at the front right corner. Listening position is approximately 13' from the front wall

$4000 is too much. I bought a mint pair from Brooks Berdan in the late-90's for $2000.
I had the RS1-B(s) for a number of years. They were interesting with respect to their sonic and visual impact in a room. I used both solid state and/or tube electronics. I did some tweaking which made a positive difference. Since then I have had a few other speakers and currently have found my final set in the Dunlavy SC-5(s). The difference between the older RS1-B(s) and the Dunlavy(s), is at least an order of magnitude.

There are many really fine speakers out there in this price range which are much better in virtually every way. My advice is to take the time to get acquainted with newer high end speakers and buy used. There's lots of good guidance found on this website.
I feel that Infinity is generally higher quality than most of Polk's stuff of recent decades, at least to my ears.  But, spend more, even on used higher quality gear.  In the end you will be happier, while having spent a little more once or twice, instead of much more over several purchases.  I wish I had been given that advice many years ago.  Save up.  Don't settle too easily, even though we all balance quality with budget, unless we are rich.  In the end, settling to easily is a waste of money, and enjoyment.  My hearing is not that good, especially in one ear.  I was actually prescribed hearing aids, and I really need them in some situations.  Too much loud construction work, and a terrible ear infection when I was a kid.  I can't express how much quality sound means to me.  I would not waste another minute listening to a low-quality system, and you will regret doing so if you settle too easily.  I read books for the quality of the writing, not just the story, and I listen to music for the quality of the sound, not just the melody.
