Here are pictures of my old B&O Pick-up set.

The pick-up weight is seen here, look at the shadows how it will tilt when the pick-up is lowered and weighs too much.

Decca Plase 4 stereo.

 Great photos and Decca Phase 4 stereo brings back such memories !

 I know of several people who bought these records thinking they were getting quadraphonic discs :-)

I think we should all pitch in to send Geoff Martin an umbrella, or at least a parasol -- he's gonna need it!

Seriously, though, what unique audio problem is this trying to solve?  The only other line array I've read about (https://www.soundandvision.com/content/dayton-audio-epique-cbt24-speaker-system-review) is trying to avoid room boundaries causing timbre change when you move around, especially eliminating "floor bounce" by having the individual speakers in the array interfere with each other.  But outdoors there is no such problem.  Also I don't understand why B&O (or Origin, for that matter) would be interested in a 70V transformer system.

Is this a way to get a broad sweet spot without using the acoustic lens?  (Just imagine that outdoors -- you'd get popping drops coming off the driver cone, like some kind of Blue Man Group performance...:-)

Not sure why Geoff Martin is mentioned here or why he should need an umbrella...

....it never rains in Struer anyway ;-)

Line arrays have been and are constantly being used in outdoor (and indoor) sound venues - everyone at a bigger event will have noticed these speaker arrays at either side of a stage, I guess.

Here is how the reasons for that can be described in short:

’One of the most impressive advantages of a line array design is its ability to mitigate the SPL fall-off over distance. 

In simple terms this means the speakers can be placed further from the listening area and still provide the required sound levels. 
Inside a home this is unnecessary. However, outdoors this effect is very desirable. 
Imagine speakers placed in the far corners of the backyard that project across the landscape 
and still provide quality sound on the deck or pool area’

I am pretty sure, that there are B&O costumers, who want this effect in their garden - to ensure that the neighbours will have some fun too ;-)))

It's lame humor: Part of his job is listening & measuring, then adjusting the DSP -- and you can't do that indoors for these speakers unless you have the theoretical boundary-less room, thus he would be working outdoors in the weather, ergo...

Oops, right you are, I'm just 30 years behind the times.  There is actual science and not just "a bigger pile of speakers" a la Woodstock merely because a single driver had insufficient maximum output for the venue size.  See https://en.wikipedia.org/wiki/Line_array
