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

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!

My first set of serious speakers were JBLs in the 1960s.  I don’t remember the model number, but they had 12” woofers and the foam grid grills.  They were great.  Sold them to buy a pair of Infinity RSIIbs, which were astounding at the time; I had them for 14 years, and then they were severely damaged in an Army move within Germany.  Replaced them with the Infinity Modulus satellites and servo-sub because the wife wanted more room.  Thirty years later, replaced them in the main system with Fyne F-702 speakers, which are astounding.

Revel f208.

Lovely. I never knew how good a speaker could be until I replaced my old Ushers with the f208s.

I have the JBL L100 Classic speakers which were purchased new in December 2020.  They do not go as low as my long gone original pair I bought in 1971.  I subsidized the bass with a single SVS 12 inch subwoofer.  It is in my office system and sounds good enough.  I drive them with a Mac 200wpc integrated. 

The f208s have a wide sound stage 

I hear people rave about the fyne speakers
