JBL PRO-4406
A studio monitor that turns up in the strangest places — including the used-gear classifieds of America's audiophile magazines.
Overview
The PRO-4406 is one of those JBL Pro models that never got the glossy brochure treatment, yet it kept surfacing in the back pages of the audio press for years. That price ladder is the most useful thing anyone can tell you about this speaker: it sat at the bottom of JBL's Pro lineup, the entry point below the 4408 and the 4410.
What that means in practice is that the PRO-4406 was the monitor you bought when you wanted the JBL Pro sound but couldn't stretch to the bigger boxes. The dealer listings repeat the same $399 figure across multiple issues — August 1991, September 1991, February 1992 — which suggests it held its used value with reasonable steadiness rather than collapsing. By April 1991 the same dealer had it at $449, so there's some price drift depending on condition and the moment.
Beyond the price and the model's position in the Pro hierarchy, the documented record is thin. The PRO-4406 turns up in the same classified columns as far more expensive monitors — the 4435 listed at $2600 in the same ads — which tells you the dealer network treated it as a legitimate Pro-series product, not a throwaway. As Audio (March 1991, p.108) shows, these classified pages were where dealers like Michigan's Audio Illusions advertised their high-end Pro-series stock alongside the entry-level models.
