I was wondering if anybody was familiar with the Stanley Screamer Dual Subwoofer System (SS-1020)

I have come across one and I am having trouble finding a spec sheet on this item. Power handling/Impedance...
The drivers in this cabinet are the 421-8LF apparently...
I found this:

Would it be safe to assume that they are wired in parallel so effective impedance would be 4 Ohms and Power handling would be 200W?
The thing that confuses me is that the driver's specs say Freq response is 35Hz - 8000Hz
Yet when these drivers are mounted in the large Screamer enclosure suddenly the freq response drops to 20Hz-80Hz?
I am no expert on the alchemy of speaker enclosures but it seems strange to me.
Any idea what its value is in the open market? Are they exceedingly rare?
Also how was this typically used?
Would it be foolish to try to use it on a mobile club platform or would I be much better off using JBL 18" Compacts Subs like the JRX 118 or MP418S?
Thank you for your time, FroggyBumBum
