A BIG speaker obviously...
It's not the first time something like that pops up.
Can't tell from the pictures whether thees are real and working specimens, but if so, can't imagine them to be efficient compared to size, weight, cost and power needed.
Still fun to see though Clap

All looks real and working to me. Unless someone really went to the trouble of adding a fake barcode sticker to the magnet, somebody has bought these from somewhere.

Waste of metal if you ask me though. You could make 6 good quality drivers with that much material and produce a better result for most applications, you'd even get 3x21 or 2x24 inch monsters if that's what you really want.

Precision Devices do 24s but they mostly get used for show and for theatre/theme park earthquake style effects where the subtle timbral difference of having an enormous drive unit vs several lesser units is worth the excess, but for general purpose applications the tradeoffs just aren't worth it. If you're able to justify a whole section of your rig for the sub-40Hz band (with 200 kilo cabinets..) that could be good, playing above that and you'll be sacrificing sound quality for rumble quality.

You have to respect the Philippines for the lengths they go to with systems, even if it seems crazy.
