If you want loud these speakers are loud of course I have them going into my amplifier, but if I didn’t, they still would be nice. Great sound you will love them. I put my money on that.

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
