Sorry to ask another basic question, but when a subwoofer is said to have an 80HZ high pass crossover frequency with a 6dB/ocatve slope, does that mean there is absolutely no 80 HZ info sent to the main speakers and a gradual increase of 6dB/octave at frequencies above 80 HZ or is there full 80HZ info sent to the main speakers and a gradual decrease of info at a rate of 6dB/octave slope below 80HZ? I hope my question isn't confusing.
