I have a question about my cabinet. I don't feel like taking the time to take the crossover out to find out my answer. In full-range mode, is the crossover to the horn simply a high pass, or is it a 6dB or 12dB/octave which would limit the highs to the twelves? I don't use the horn. Never have on a bass cab, so I need to know whether any highs are prevented from getting to the twelves. Thanks!
