hey there people! ive a quick question about my current 6x10 cabinet if someone has any thoughts! ive just noticed that only the two two speakers in the cab move now on other combos ive had they all move with the same velocity, now is this normal in a 6x10 or should they all punch the same? ive never have one before so im worried it might not be putting out its full punch when playing. thanks to anyone who has any insights!
