optimus 9 speakers

[bookasan]

Found a pair of Optimus model 9 speakers.
look to be probably 70's with I think 4 tweeters along the top in a row and about a 5" high grill along the top of the back (possibly more tweeters?). Either a 12 or 15" woofer and I think it had 1 or 2 mids as well. I can't find any info on these, but they look pretty cool.
Anyone ever seen these?
I bought a pair of Realistic Mach Ones from this same store a while back for $14.00

What is going on in the back?
It looks like it had some sort of grill cloth in the back

I have a pair of Optimus 900, and they also have the open-back midrange. Pretty nice pair of 12-inch, 3-ways.
I'd sell 'em for a good deal all round.

I got a pair from my father. I power them with a 110w sansui integrated amp, these rock pretty good. Midrange is dipole which sounds good, but gets congested if placed to close to a wall.
