Hey guys I’m new and this is my first post so I hope I’m doing it right. I have a pair of Polk speakers that I can’t find any info on and I was hoping you guys can Help

My understanding is that those were intended to be used in an early Dolby Prologic surround setup in the late 1980s/early 1990s. Interesting design and a novelty but not really useful today. Mainly intended for ambient effects rather than discrete surround in each channel in use with surround formats now. Here's an old thread with info:

I had a set of those I donated to a family member. He uses as a surround set. The x-overs were never updated, but still sound ok.

Driver and cabinet wise they look a lot like Monitor 4's
