Does matter what speakers you use for power metal? JK
I heard some sibilance on my VP150 last night with Leonardo DiCrapio in the film "The Aviator". It was only his voice, off and on throughout the movie, during studio scenes - never outdoors.
This is not a common occurence on the VP150, from my experience. It was the source, plain and simple. Maybe a more constrained tweeter would have helped, but I'd also then be missing stuff I'd like to hear.
In your case, aside from scrapping the metal, maybe resistors on the tweeters would help. 30 day return? Good luck.
