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. So easy, a caveman could do it.
After several failed attempts, some sweating, and a bit of cursing, we were able to lock the replacement drive-unit into the Giya cabinet. Success! And then we realized we’d forgotten an O-ring…
John Atkinson measures the distance from his microphone to the Giya’s midrange drive-unit. For a larger view, visit <a href="http://forum.stereophile.com/photopost/showphoto.php/photo/2218/passwor… Gallery</a>.
After we lifted the big Vivid Giya onto a rotating platter, JA got under the hood and connected the speaker cables to his test amp. JA <i>loves</i> it when speaker terminals are hidden beneath a speaker. For a larger view, visit <a href="http://forum.stereophile.com/photopost/showphoto.php/photo/2217/passwor… Gallery</a>.
JA uses a little camera to monitor the rotation of the speaker on the platter. The platter turns at five degree intervals while JA measures impulse response. For a larger view, visit <a href="http://forum.stereophile.com/photopost/showphoto.php/photo/2216/passwor… Gallery</a>.
JA positions his microphone in such a way that any room reflections become insignificant. For a larger view, visit <a href="http://forum.stereophile.com/photopost/showphoto.php/photo/2215/size/bi… Gallery</a>.
JA uses a different mic, set at a much closer proximity to the drive-unit, to capture the side-firing woofer’s nearfield response. For a larger view, visit <a href="http://forum.stereophile.com/photopost/showphoto.php/photo/2214/size/bi… Gallery</a>.

In <a href="http://blog.stereophile.com/stephenmejias/now_on_newsstands_stereophile… April issue</a>, Robert Baird talks to Okkervil River’s Will Sheff about his recent collaboration with Roky Erickson, the wild-eyed frontman for the famed 13th Floor Elevators.
The May 2010 issue of <i>Stereophile</i> is now on newsstands. Jon Iverson opens this issue by exploring “The Holy Trinity of Audiophiledom.” The idea was born on the morning of February 9. I had sent an e-mail to Jon, directing his attention to <a href="http://forum.stereophile.com/forum/showflat.php?Cat=0&Number=82398&an=0… post</a> in our forum regarding one reader’s experience with cassettes and cassette decks. Jon responded by directing <i>my</i> attention to that morning's <a href="http://cgi.stereophile.com/cgi-bin/showvote.cgi?663">Vote question</a>, which also dealt with cassettes.
