Room correction or anything else you mentioned does nothing to get rid of the hiss from the speakers. What will a sub do to get rid of the hiss when it’s coming from the tweeters? Is the person running tube electronics, if so, that is probably the cause.
Right. Good catch. Brilliant! Running tube electronics is definitely the deciding factor. Tip of the hat to you, stereo5! Which tubes do you recommend for the longest tweeter life?
