Need help to ID these slot clones

[LE15-Thumper]

Afternoon all, was wondering if anyone recognizes these slots ?
Not tags or markings.
Internet search turned up squat.
Any help is appreciated.

Thanks

Do a search in general audio discussion for 2405 UHF clones

Maybe P Audio?

Magnets look like Gauss, but I've never seen them offer a "slot."

That is a Monarch 250 sl from Monacor.
There has also been a 300 sl but that one had bigger ribs.
The term sl is for slot and there are also rd (round) versions
wich are the bullet types and go up to 350.


D.A.S. offered the K-2 slot tweeter as well.
The three bolt pattern on the front looks alike
but they have more and different ribs on the back.
Also the plug is not sharp, its blunt.

We have a winner!
