I’ve been learning more about subwoofers, and it seems like I will be adding some soon, but the details are proving quite difficult to work out. I’m leaning towards passive subwoofers, with a separate amplifier receiving signal from the pre-amplifier. Interestingly, some people prefer a crossover at 100 hz, and others prefer 50 Hz with a very steep LPF. Then there’s the discussion about the HPF to the SL speakers also.
