Overview
The Kenwood KL 666Z is a 4-way loudspeaker system made by Kenwood. It was produced from 1981 to 1982, as documented in an official HiFiEngine manual. The system has a dedicated super tweeter, part number T03-0112-05. It runs at 8 ohms and measures 1.5 inches. Detailed specs for the full speaker system aren't available, but a discrete super tweeter suggests the design put weight on extended high-frequency reproduction.

Market
The KL 666Z turns up now and then on the secondhand market. One listing was observed at BGN 610 on Bulgaria Bazar BG as of February 26, 2026. Owners use replacement crossovers such as the Monacor DN-4, which points to failure or availability problems with the original units. Original super tweeters (part T03-0112-05) are currently sold out at Oaktree Vintage, with no confirmed restock date. One owner reported buying a pair at a yard sale for $20, called it a decent deal, and said they used them for 20 years.
