JBL L16 Decade (1974)
The JBL L16 Decade has almost no paper trail. What survives is oral history, or more precisely forum history. It comes from a single long-term owner who bought a pair new in 1974 and has lived with them for fifty years. That's a thin base, but it tells a consistent story: these were popular, well-regarded bookshelf speakers in the early 1970s, priced at $129.50 each in the 1974 catalog.
The L16 was a 2-way bookshelf design with a 10-inch woofer and a 1-inch dome tweeter, crossing over at 2500 Hz. Impedance was 8 ohms. Power handling was rated at 15 watts continuous and 60 watts peak. Each cabinet weighed 30 pounds. The "Decade" name tied it to a JBL series of the period, though no other models in that line are documented in the available material.
Audio (1974, p.103) covered speakers in that period, which gives a sense of the competitive landscape the L16 sat in, though the L16 itself was a 2-way design.
The long-term owner's account is the core of the record. They report the speakers "sound great" and "still work well" after five decades, with two caveats for anyone shopping for a pair today. First, the foam surrounds on the woofers will eventually rot, and this owner replaced theirs. Second, the dome tweeter is described as "a known weak point," and replacement tweeters are hard to find. The owner's advice for buying used is to check the foam surrounds on the woofers first.
Beyond that, the documentation is thin. No dimensions, frequency response, sensitivity, or cabinet construction details have surfaced. No production run dates beyond the 1974 unit. If you own a pair or have period literature, the archive would welcome the details.
