Can you identify these Polk Audio speakers?

[wired4sound]

I don't have a photo, and all I know is that they're old three way speakers about 20 inches tall, by about 10 inches roughly square. I have the opportunity to purchase them for 160 Australian dollars (speakers are more expensive in Australia unfortunately), and I'm trying to work out if they'd be a good match for my Sansui AU-555. Is anyone here able to i.d. these speakers even on such bare information? Or are you able to offer a general comment on the synergy typical Polk Audio speakers might have, if any, with my old Sansui?

(Am currently using Pioneer CS-77 speakers, but want to upgrade.)

monitor series,, maybe 7's,, are they fused on the back? What color is the tweet,and does it have a "dimple" in the center?

Here's a Monitor 7A:

Here's an early Monitor Series Model 10 ("Monitor 10"):

Here's a Monitor 5(B?):

Note that the "woofer" cones are in fact passive radiators, not driven cones; these are actually two-way speakers that are effectively ported (even though the cabinets are sealed) via the PR.

There is a good form and some information on legacy products at Polk's website:

From my user name you can guess that I have a warm spot in my heart for most vintage Polks. If they are in fact monitor 7 then go for it. I am using a set for center channel and rear center in my home theater. I only paid $50 US, but I guess you won't have the same luck in Australia. The monitor 7 came in many versions, the original followed by an A, B and finally C. I own the C. The original and the A came with the peerless tweeter which is the most desirable version. My C's sound sound warm, and natural. I love cranking up the volume and watching the mid and PR dance to the tunes. BTW Polk offers a replacement tweeter for about $48 US each I think it's called the RDO and it's suppose to sound better than the 'Silver Voice Coil'. Tomorrow I am picking up a pair of Monitor 5jr version 2 that will replace my rear surrounds finishing my vintage Polk HT, I will finally have a different Polk tweeter to compare mine to. I'll then have to determine if I want to replace the tweeters on my fronts RTA12c's and the front and rear center Monitor 7c's to match. This hobby never ends! Good Luck. BTW Polk has a dedicated vintage forum, google 'Club Polk Forum' for more Polk information.

Thanks for the pictures and guesses. I'll try and have a look at them today and take a photo.
