Early JBL Pyramid Speakers/Subwoofers?

Hi,
I just picked up a pair of "Art Deco" Looking vintage speakers at a local goodwill.

They have no markings at all on them, so i opened one up to see if i could find anything (need to glue a plastic frame thinger back on anyway).

there is just one 8" Shielded Floor-Firing Driver with JBL on the Dust Cap.

I say they look Art Deco because they have very nice looking squared cabinets that set on a plastic lifter/stand/chamber for sound?, with a lift at the top with a pyramid shaped white cone coming downward.

Much likes this design (but flip it around and add the bottom part):

Ive looked through the catalogues here, as well as online... and i cannot seem to find anything about them.

If anyone has any sites, info and what-not, please post.

Thanks!!!

They look to be 1970's-80's Range.

Numbers on the Driver:
JBL 71861 60T-JBA
5808401001

Well,
it looks like this is not a matching item...
The JBL driver looks to be a later subwoofer (90's)
and the enclosure looks to be 70's, with holes of where a smaller driver/s was mounted inside.

I still dont have any idea of the cabinet make, these are very unusual enclosures and very apealing.

Can you post a photo?

The square cabinets and the pyramidal diffuser thing, sound like probably one of the JBL Aquarius models. If it's a single 8" woofer, probably an Aquarius 4, I'd guess...

Does the cabinet look like this, by chance?
