What model speakers are these?

I inherited a pair of ads floor standing speakers but don't know what model they are. on the back there is an amp that says PA1 but i think that's just the model of the amp and not the speakers all together. they have two 6.5" woofers (i think that's the size) and then a .5" tweeter and a 1-2" tweeter. i know they are also older models.
