very good speakers and very strong . good sound

### ⭐⭐⭐⭐⭐ Great performance

### ⭐⭐⭐⭐ Not what I was expecting....but....
*by B***E on August 30, 2022*

The seller was great in returning my item. The speakers didn't carry the low frequencies that I thought they would. However, I was running these with just my stereo and not pushing them with an amplifier. The price was good, the packaging was excellent and quality seemed very nice. Just not what I was hoping for with the bass response. I have to give four stars even though I didn't keep them. For most people, I think they'd work well.
