Que fiasco!!! Ni un solo tema de Zulma Lobato!
mmmmm no se si son lo mismo... los walsh son de radiacion omnidireccional, gracias a la geometria de su transductor, los de linkwitz usan transductores convencionales y de hecho en alta frecuencia radian solo en 2Π
Bill, I've used DBLTs to design stuff for nearly 2 decades.
While a DBLT series would be used to confirm approval of the final product, an engineer would only use a DBLT to make difficult & subtle decisions.
A true golden pinnae (someone who has been proven reliable in a LOT of DBLTs) can often pick stuff up in seconds so much of the design work could be sighted. But even the best ears in the business are as prejudiced and pig headed as the most raving lunatic Golden Pinnae reviewer. There are ears whose opinion I respect blind that I would never consider sighted (including myself).
When you do a lot of DBLTs, you find out all sorts of stuff .. some of which I've pontificated on this forum in various places. eg practically ALL HiFi reviewers are deaf (with a VERY small number of exceptions).
ALL self declared Golden Pinnae are deaf. No exceptions
I could go on but that would further hijack Tom's thread. Most of the tests were of speakers but there were important tests on amps, EVIL digital and other stuff too.
I don't think most people realise how expensive it is to do proper DBLTs. A DBLT is a measurement and your instrument, your listening panel, has an accuracy that has to be checked & calibrated regularly.
But to come back to amps, I posted something something on another thread on what features would result if DBLTs were the MOST important tests conducted on amps. It will be a long time before amp makers & designers are brave enough to do this.
o Pluto ?¿?¿? 
No me estás convenciendo de hacerlos con los Leea 812RE y los Pioneer
