What is the most preferred revel or jbl speaker you have owned and why do you prefer it

Of the 3 revel speakers I have, I prefer the f52s.

fo all newer jbls use a horn tweeter?

how would you characterize the Klipsch jubilee’s sound?

My first set of serious speakers were JBL Olympus, with the JBL 001 system. I would still own them but my wife convinced me they were too large for our living room. I sold them for exactly half of what I had paid for them in the 1970’s. If I had kept them, I could probably have sold them for twice what I paid for them. In any case, they had a big sound with clear high frequencies, that I really liked. My current speakers are Sonus Faber Electa Amators (Original version), so I can't  complain.

Those sonus fabers are very nice. 

To simply answer your question, JBL-L100’s. I bought a pair new from the factory store, J.B. Lansing in Burbank, CA in 1976 for $600. Despite others commenting, I loved those speakers. I was an apartment dweller in those days and couldn’t and wouldn’t have owned more powerful speakers because I wouldn’t have been able to crank them up. They served me well for speakers in the pre-subwoofer era. 

I currently have an all McIntosh System with a C2800 preamp, (2) mono-blocked MC 275 Vl’s running through older KEF Reference 205/2’s and (2) REL 812 subs.

Thanks for the question!
