That is the (expensive) commercial version.The DIY version is, of course, much cheaper and very easy to implement by sourcing the Seas drivers and kits from a distributor in your area of the world.
Here in the USA, Madisound offers all the necessary equipment.But there are myriad other dipole woofer schemes available other than Linkwitz version.
I first saw something akin to these back in about 1983. IIRC.Dave.
