JBL J213PRO (1985–1986)
The JBL J213PRO is a small 2-way, bass-reflex bookshelf speaker introduced in 1985 as the younger sibling of the highly successful J216PRO MarkII. It sold for roughly one year before being discontinued. Its brother stayed available into the 1990s. The J213PRO was priced at ¥25,000 per unit (around 1986). An optional ceiling/wall mounting bracket (MB213) was sold separately at ¥16,000 for a pair.
The speaker pairs a 10 cm cone woofer with a dome tweeter. The tweeter diaphragm is pure titanium, vapor-deposited, the same tweeter technology as the J216PRO MarkII. The woofer cone is pulp-based with a special new material laminated onto it. The enclosure is a compact bass-reflex design. Specs are modest: 8 ohms impedance, 90 dB/W/m sensitivity, 65W continuous program power handling, and a frequency range of 65 Hz to 20 kHz. It measures 210 x 296 x 225 mm and weighs 5.6 kg.
Stereo magazine reviewed the J213PRO in its January 1986 issue. The reviews were mixed but generally respectful. 石田善之 found it unenergetic overall. He called the low end "surprisingly fleshy" for its size, but said vocals lacked drive at higher levels, and he thought it suited quiet listening. 金子英男 felt it was better placed horizontally and suited to larger rooms as a supplementary speaker rather than for close listening. 福田雅光 described it as punchy with an "American dry atmosphere," though with slightly coarse texture and somewhat sacrificed transparency. A follow-up review in Stereo (February 1986, as quoted in the owner's blog) by 井上良治 was considerably more positive. He praised the balance as "top-class among JBL speakers" and noted the woofer-centered sound had excellent driver integration.
Surviving owner accounts point to a few common issues. The resin panel holding the tweeter is brittle and prone to shattering. One collector reported a tweeter arriving with its baffle broken into pieces. The original crossover uses a 2.2μF electrolytic capacitor for the tweeter, which owners typically replace with a polyester film type. The push-snap terminals and the W1/4 mounting bolts are also noted as weak points. One owner who documented a full restoration described the midrange as dense with a pushing-out momentum, the treble relatively quiet, and the lowest bass notes limited. He ended up calling it "a vocal-specialized speaker."
Good condition used units are hard to find. A reference purchase price of ¥2,400 was noted in late 2024, and a Yahoo! Japan auction in March 2026 closed at ¥4,510 after 9 bids. The short production run and the fragile tweeter panel make intact examples scarce.
