Dynaco A-25, the Large Advent, and JBL Century L-100: which one nad the best sound??

I owned both Dynaco A-25 and large Advent at one time in the distant past, but heard the JBL L-100 many times in friends' systems. I know I liked them all and would have been happy with any one of them at that time. As faded as my memory is I believe I might have liked the JBL the best...??? Best, Rob

The JBL L-100 Century was my first pair of real speakers.  IMHO, one the best rock-n-roll speakers ever made.

Wish I still  had them...

2 pairs of large Advents, stacked are even better  HP in TAS loved them.  The JBL's are great for rock but not so much for Jazz or Classical.  The JBL doesn't need too much power to drive them where the Advents and Dynaco do.  If you like all kinds of music, the large Advents would be the best bet.

The Dynaco A-25's were my first "hi-fi" speaker, with a PAS3x and a Stereo 70.  I went from there to Large Advents, then to stacked Advents.  A roommate during that last time had JBL L-100's; he put them in storage while we lived together (for about 9 mos).

Had the DYNACOS , then the ADVENTS, then EPIs, and then JBL-100s back in my young days at university.

JBLs reign supreme .... Not even close.

BUT .., couple qualifiers:

(1)  these were a "California" sound speaker ( Google the term ...) with heavily spiked frequency curve In the  treble and bass to accentuate a tailored pop and rock music presentation  of the era.

(2) none of the OPs suggestions will match up to current era standmounts with their improved design build,  and crossovers ... Full stop..Remember that all of these geezer-rock era speakers  have ultra-cheap basic spring-loaded speaker binding posts limited to 18-gauge zip cord cheap and crappy speaker cable posts that need replacement, and likely need speaker surround re-foaming and maybe even new caps .

if you favour nostalgia and favour 70s hard rock played loud, the JBLs will be your boomy bass party speaker... No problem.

If you are looking for a non-coloured balanced musical presentation especially with all the other music genres, look elsewhere .
