JBL Tweeters
JBL's tweeter evolution tells the story of high-frequency reproduction in the 1970s - from the cone tweeters of the early L-series to the aluminum-deposited dome designs that became industry standards.
Cone Tweeters
1970-1972
LE20
The original cone tweeter from the L100 Century. Small, efficient, and characteristic of the early L-series sound.
1972-1978
LE25
Improved cone tweeter used in the L26 Decade and later L100A. Extended high-frequency response.
Dome Tweeters
1975
066
JBL's first dome tweeter! Used in the L166 Horizon, marked a major shift in JBL's high-frequency design.
1978-1983
044
Aluminum-deposited phenol dome used in the L96 and L112. Smooth, extended response to 20kHz+.
1979-1982
033
Resin-impregnated linen dome for the L150. Refined, natural high-frequency reproduction.
