The ADS L990 is a classic, vintage three-way floor-standing tower speaker made in Boston, Massachusetts during the late 1980s. It is highly regarded by audiophiles for its smooth sound and clear vocal presentation
Key Technical Features
Three-Way Design: It features a 10-inch woofer for deep bass, a 1.5-inch sticky dome midrange for vocals, and a 0.75-inch dome tweeter for clear highs. [1, 2]
Sticky Dome Drivers: The midrange and tweeters use a famous “sticky” soft dome design. This gives the speaker its signature smooth sound. [1, 2, 3, 4]
Durable Surrounds: Unlike other vintage speakers that use foam, the L990 uses butyl rubber surrounds on the woofer. These do not rot over time. [1, 2, 3]
Cabinets: The towers came in premium wood finishes, like light oak, and featured heavy metal front grilles. [1]
