Soft dome tweeter

The soft dome tweeter is a particular type of tweeter invented and patented in 1967 by Bill Hecht, a renowned pioneer in the early days of audio engineering and the founder of Phase Technology.

Hecht states that he was confronted with what seemed a mundane problem: When showing speakers at various audio shows, onlookers often poked at the two-inch dome tweeters of the display models, sometimes cracking them.

He set out to make a soft, mock tweeter that wouldn't crack when prodded.

“I brought it back to the lab, and I thought it might possibly make a good mid-range if I coated it,” Hecht recalls.

After it was patented, the soft dome tweeter became an industry standard and was licensed almost immediately by all major audio companies in the world including Philips, Peerless, McIntosh, Sony, JVC, Yamaha, Pioneer, Kenwood, Shure and many more.
