On Thursday, April 15th, I accompanied John Atkinson to Wes Phillips' home, where we replaced a midrange unit on the Vivid Giya and conducted a set of measurements. See that itsy-bitsy little hole way at the back of the speaker? Properly installing the replacement drive-unit meant lining up that itsy-bitsy little hole with the tapered end of the transmission line and locking it in place with a hex screw.
