EMI extraordinaire
A further update. After more research this evening, I've stumbled across some new information.
Over on the Steve Hoffman forums there are several former Abbey Road and Motown engineers who post. In one post was described two speakers. One being the REDD 36 column speaker. These were said to use the EMI elliptical drivers and powered by an integrated Leak TL25 power amplifier.
He then described what are referred to as the Dutton speaker, named for one Dr. Dutton of EMI fame. These looked externally similar to the Altec 612 cabs in the control room at Abbey Road. However, their internals were all different. Used a closed cab "infinite baffle" design. They used a modified Wharfedale 15" bassd driver with a pair of EMi manufactured tweeters mounted across the bass speaker.
That last entry is the kicker. Going back to the original picture I posted, down in the bottom, there is a picture of Lennon with sunglasses on and the white elephant speaker behind him. You can see a bar running across the large woofer. These must be the tweeters.
Another possible Dutton link is the original EMI DLS-1 speakers. A search of the internet and subsequently, past fleabay auctions, drew several parallels between the white elephant speaker and these speakers. They were powered by an EMI STD/373 power amp, which are very similar to the Leak TL25s. They used 13x8 EMI 92390 G elliptical drivers. They also had two GEC 1853 Hi-Flux presence unit tweeters.
