I bought these to add Atmos capabilities to a a receiver I had at the time.
I'm no longer into home theater and I'm selling these. They were made to plug into another speaker. I bought them cheap as there were no standard speaker plugs. I simply hooked up the pins on the front to speaker wire and they worked fine. The speakers sit on top of your current front speakers or wherever you want them to work best. I bought the proper speaker connectors, but never installed them. (Included in sale)
They're in excellent condition and work well.
