The media could not be loaded. I bought 2 speakers and when I received it 1 of the 2 was bent up. I did a refund for a replacement and the 2nd one was bent up also. I attached 2 photos(one good speaker one bent) and a video comparing them so you can see the difference and make a decision yourself if its acceptable. A shipping label is just placed on the manufacturers box, which is barely bigger than the speaker, and has little to no protection. It's definitely not Black diamond's fault but Amazons because they are the ones fulfilling and shipping the order. Edit: I got impatient and installed the speakers in my car. They are paired up with a Taramps DS 440x4. They sound very good and they also get loud. Previously I had Recoil 6.5 component speakers in their place. The Recoil speakers also got loud(but not as loud as Black Diamond) but they always had ear piercing very high notes. The Black Diamond speakers have a way more full and balanced sound that doesn't hurt the ears without any EQ It would take a lot of force to bend a speaker like that, so I'm just worried whether it will die sooner or what. ... show more

These speakers blow higher priced speakers out the water I used to be a fan of Rockford Fosgate for the longest but they are very pricey and just can not compare to the sound quality of these black diamond speakers (they are the same as the ds18 zt6 pros just a sub brand) buy these speakers you won’t regret it I’m powering 4 with a skar audio rp150.4ab amplifier and they do good on it , im sure with more power they will sound way better but they do fine on this amplifier ... show more
