No idea. The cabs I have are old though. I got em out of a nightclub that went under some time ago, and they were there for ages. 10 plus years?
When you ask 'who is the original designer' do you mean the mini scoop design in general?
If the plans cant be posted, can someone send them to me?
I have the DAS Action 118A in my possession, which I measured, and have the plans for. The Action 118a is A VERY similar enclosure to the YORK801P, but the final stage of the port flare is slightly different.
We can do a swap? York801 plans for the DAS Action 118A. Would like to do some experimenting.
