Modifying the Tang Band W4-1052SA driver

A Gem-Tac glue ring, 1.5 mm in diameter and 9 mm in from the inside diameter of the surround, plus a simple equalizer circuit brings the Tang Band W4-1052SA to high fidelity performance equal to any four-inch driver available.  The physical cone modification add so little mass that original T/S specifications remain valid.  With the modification, the 1052SA becomes a great choice for center channel or surround speakers in a home theatre.  Add a sub woofer for frequencies below 100 Hz, and the driver satisfies every requirement of high fidelity main speakers.

McKenzie Acoustical Design does not sell Tang Band drivers.  I offer these modification designs free of charge.  If you decide to buy these drivers and make our modifications, I ask that you buy them from Parts Express and link to their Web site through the following link.    There is no cost to you, but Parts Express will pay McKenzie Acoustical Design a small commission for the sale.  I will use that revenue to produce more driver modifications.
