Jordan-Watts
The Jordan-Watts module combined Ted's work on cone flexure and the metal cone technology developed by Brittain.
In the interest of low-frequency linearity, Ted also developed a novel rear suspension comprising three tangential beryllium cantilevers as an alternative to the conventional corrugated cloth method. This driver became an icon and sold consistently for over 20 years. It's square, modular design enabled it to be used in a range of enclosures, either singly or in pairs for increased power-handling and output.
Jordan-Watts produced both the driver and complete loudspeaker systems. The most famous of these is the Flagon, a ceramic enclosure designed for both its appearance and acoustic qualities.
The Jordan-Watts module continued in production until well into the 1970s, going through a number of versions. They are still highly prized on the second-hand market and fetch high prices on eBay.
Ironically, when first produced, the concept of the Jordan-Watts module was treated with scorn. The perceived logic was that the cone should be as rigid as possible and that metal would ring. Now, 40 years later, remarkably similar designs are emerging from Asia and elsewhere, closely based on Ted's pioneering work.
