JBL 3677

Not much is documented about the JBL 3677. A trade item in Mix Magazine (June 1996, p.124) listed the JBL 3677 Screen Channel System as a loudspeaker aimed at small and mid-sized theaters, priced at $640. That is nearly the entire verified record.

No production years, specifications, driver configuration, dimensions or design details survive in the available documentation. The model appears to have been a cinema screen-channel loudspeaker - the "Screen Channel System" name in the period listing supports that. Beyond its marketplace appearance, almost nothing else is recorded.

Known facts, in full:

• Listed as "JBL 3677 Screen Channel System"
• Described as a loudspeaker for small and mid-sized theaters
• Priced at $640 at the time of the 1996 listing
