where can u get these test tones from mate? I dont have any issues with the speakers most of the time its just when I turn them up n possibly on certain tunes but it does feel as tho something aint right as tho they're cutting in n out or something like that but litteraly only for a tiny split second, just reminds me slightly of when tweeters are damaged but not to that extent as when tweeters are damaged its very clear but not mine. apart from the high volume I cant really complain tbh, they play perfectly fine and clear otherwise.
