I am a fanboy of scientifically engineered speakers with defensible price/performance ratios, and Harman International is among the best in that regard. I appreciate the Interlude, Intermezzo, Prelude, Beta, and Primus speakers for those reasons.
I stand by what I tried to convey, and that is money towards a used pair of IL-50s is better spent on something else, whether that something else are the IL-40s or a newer Infinity tower speaker or something else. I would rule out the IL-50s because of the integrated subs alone. They are unnecessary, problematic, and inflexible. And, I personally would not buy old Interlude series speakers unless they were particularly cheap because they are not going to be much of an upgrade over a pair of very affordable Primus towers. With each passing year, the calculus changes more against investing in the Interlude series.
The Primus 360 and the Infinity IL 40 have the NRC Curve built into them, the IL 60 does not.
I don't know if the IL 50 has the curve built into them, or not, but I don't like the 2 way Interlude Speakers as much as the 3 ways.
The IL 36 is truly an excellent center channel, with nice warmth on male voices, and mates well with all the 3 way Interludes.
I would jump at the chance to get a pair of either IL 40's or IL 60's, even today. IF you can find a pair or IL 60's, it is highly doubtful you will ever need external subs.
I have a 20 by 24 foot room, and a pair of IL 60's rattle the room, and pressurize it completely.
The IL 60 and the IL 40's are quite different speakers. The IL 60 is ruler flat, quite possibly THE Flattest speaker ever produced by anyone, anywhere!
This mean it will not be as "room friendly" as the Primus 360 or the IL 40 that have the NRC Curve.
But, if it likes your room, or you are willing to do some room treatments, and re arrange furniture a bit to give it what it wants, it is capable of breathtaking sound.
And yes, Sean Olive of Infinity sent me the curves of both the IL 40 and the IL 60.
I have also seen the Primus 360 curves.
I have not seen the IL 50 curves, but I tried a pair of the Interlude 2 way 6.5 inch 2 way speakers that the IL 50's are based on. They were just OK, and did nothing special.
The IL 40's are outrageously musical, especially if used with a sub woofer.
You can listen to them forever, w/o fatigue.
They have a wide image, but image depth could be better, compared to my old B&W 801's.
The IL 60's CAN be better then IL 40, but only if you are willing to make them like your room.
