JBL 4518

Name: JBL 4518
Brand: JBL

Little is documented about the JBL 4518. The most telling piece of evidence is a ProSoundGear.net thread titled simply "The JBL 4518 thread," in which a collector says they have been searching for information about the 4518 and its history and found very little. That about covers the public record.

What is known comes almost entirely from second-hand listings. One describes the 4518 as a vintage loudspeaker system rated at 8 ohms, 200W power handling, with a frequency range of 40-16000 Hz. It weighs roughly 54 kg (a second listing says 55 kg, so the record disagrees here) and measures 70 × 45 × 42 cm. An eBay listing calls it a "Vintage 500W PRO Sound PA Speaker" from Japan, which conflicts with the 200W figure from the other listing. One forum member guessed it might be similar to the 4341, or part of a series with the 4540, but hedged both guesses with "I am not sure." No formal spec sheet, no period review, and no confirmed production years have surfaced. The model does not appear in the period specification tables that list other JBL studio monitors of the era, such as the 4206 and 4208, which were listed with sensitivity ratings of 87dB and 89dB respectively (Mix-Magazine, March 1993, p.113).

What we can say with confidence:

Type: Loudspeaker / speaker system (described as a PA speaker in one listing)
Impedance: 8 ohms (single listing)
Frequency range: 40–16000 Hz (single listing; not a full frequency response spec)
Dimensions: 70 × 45 × 42 cm (single listing)
Weight: approximately 54–55 kg (listings conflict)
Power handling: 200W vs 500W (listings conflict)

If you own a 4518 or have documentation, this page could use your help. The existing record is thin.
