@d2girls Avantgarde would look great but I love that these look like actual pipework you would see in an exposed ceiling.
Interesting. I’ve seen a few pictures and video of those beasts and they certainly seem intriguing.

Though being an MBL fan, I'm not sure I’m seeing anything very novel in this design.  Unless I misunderstood that link, it seems to operate via a driver that flexes in a way similar to the MBL drivers.  But MBL is able to do it through most frequencies, so MBL strikes me as well ahead of this design.  (Again, I certainly may have missed something important).
I'm really not sure what is going on with the mid-woofers. It looks like they actually are direct-radiating, and the tube is acting as a sealed cabinet, no?

I can't find anything about the cost. Anyone else have luck?

Best,

Love the innovation and new thinking. Does anyone know the price? LOL to the comment “glamorized sewage pipe”.
