JBL l100 speaker impressions? (original)

Lots of hype around the L100. If you break them down, they are not so special.

The 123A woofer is the younger sibling to the D123 which was a high efficiency, full range driver of the times. Replace the aluminum dust-cap and add some mass to the cone, you have the 123A. Neither of them do well in small enclosures.

LE25 tweeter is the younger sibling to the LE20-1 and LE20 which are all paper cone tweeters. In my opinion, they sound pretty good but not a good match for a 12" woofer alone.

The above woofer / tweeter combinations were used in several models, none of which are great sounding speakers.

The LE5-2 came later to fill in the midrange where the woofer / tweeter combination couldn't reach. Not much thought went into the crossovers so although the midrange was there, it was never really refined until much later in the 1970's.

If someone wants authentic JBL speakers the size of the L100, there are much better sounding options. Just add some fancy sculpted & colored foam grills and you're all set.

I don't disagree with the posters who suggest that a good speaker should sound good with all kinds of music. The problem is that most speakers involve compromises, and consequently most speakers do sound more successful with some types of music than others. Calling a speaker a rock speaker doesn't mean it won't sound good with blues and jazz or folk - sorts of music which favor a close up type of recording - but it does suggest that it may be less convincing with symphonic music.
