I really dont know what you mean by rock? If its SPL well sure. I have had my horns to 106 db and the sound was very stable and not congested , very detailed. And it only took around 8 watts. But! at that level for any amount of time and it can and will cause hearing loss. Besides i frequented many concerts in my wild youth and after one Dead concert i could not hear properly for about one week. Too much hearing has already been lost, i dont wish for more. ron
