The S/2600 and S/3100 were designed specifically to create a superior stereophonic experience. However, the "S" does not imply stereo, but rather soundstage. At least that's what I remember reading, though I couldn't find a specific reference in my S/2600 owner's manual.

However, the manual does go on and on about soundstage, so it's as good a guess as any until someone finds an exact quote.

As I recall the "S" stands for Signature as in Signature Series. I think the word "Signature" is scrolled on the front metal trim piece, at least on S/3100.

I seem to recall seeing a JBL product years ago with the name Signature attached to the loudspeaker.

Iím a little curious myself but as of yet havenít found anything on the JBL professional website that says so.

Signature was an old series that had James B. Lansing's "signature" originally appended to it.


I think it applied to some of the older drivers as well.

I've never seen "signature' on my S/2600s or the manual. All the pictures I've seen of the actual units only have S/2600 or S/3100 on the front.

Anyone got a picture?

Thinking back, I believe the guy I purchased the S3100's from told me they were from the Signature Series. He was a dealer of high end JBL stuff back in the late 80's early 90's in Marin County. Either that or I dreamed it at some point which is very possible!:yes:

From The Stereo Sound Sticky from Don McRitchie:

The next significant home speakers introduced by JBL were the Signature series of 1995, consisting of the S3100 and S2600. These were an adaptation of the asymmetrical horn concept used in the Everest. They were both two-way designs that used a smaller version of the Everest horn, called the H2600, which was driven by a 2426H compression driver. The systems were differentiated by enclosure and bass driver sizes. The larger S3100 used the ME150HS 15" driver while the S2600 used the ME120HS driver
