This particular crossover has recently changed its layout (see photo I uploaded), compared to what we see in the product photo on skroutz. I put it on 50W, 8Ω JVC speakers from an old stereo and they felt alive again! Proper frequency separation and very good sound quality. It comes with pre-wiring with connectors, so all you have to do is connect the speakers!

I give it 5 stars with reservations because I can't understand if the crossover is good since I have connected it with Sony woofers from some old speakers I had, and for the tweeters, I used some cheap horns and they sound like they are squeaking, so I don't know if it's because of the horns or the crossover. I will try it with tweeters and update.
