Yes Martin, that would be the chap...Sorry to hear of his passing away, it must have been pretty recently or i'd have thought we'd all have heard about it :scratch:
Probably me missing stuff as usual :doh:

2006 was when he died
ARA's Quad were arranged in two unconventional alignments.
The most recent was two pairs, each channel of which was made up of two speakers arranged closely at 90 degrees to each other. Each unit was loaded with a very heavy lump of steel on top.
Prior to those there was a semi-circular array of 57's - 14 units (I think).
The arragement ARA used with his fourteen 57's was two vertical stacks of 4 each side at the front, with two arrays of three speakers each at the rear. The speakers at the rear being rotated through 90 degrees, so they were on their sides; or if you will, a horizontal assembly of three speakers each, the entire assembly orientated vertically. I assume this was done to 'diffuse', or ameliorate the treble beaming, prevalent with these speakers.
