How are Beethoven's Sub drivers mounted?

Apparently there are 4x 12" woofer mounted in these subs. How is that possible since the front plane does not look so wide?

Perhaps Isobaric??

Or Push push??

I thought about that, but SL argues against such arrangement:

Electro-acoustic models

Basically I want to increase the bass output of my dipole woofers by adding 4 more drivers.

I don't think the bass enclosures look particularly small.

They are 2.75" wider than the woofers, so hey could have been made slimmer.

Stacked W-baffles?

Crazy - that's another good way of packing them in there. I bet the build assembly isn't especially easy...

I guess one of the sidewalls has to be removed if drivers have to be replaced. But after that it isn't that complicated.

Very clever indeed.

I've got a 3-way project which will be great with additional woofers I think...

Anyone got internal pics of these subs?
