“As I mentioned previously, the CR-1 confers a big advantage by splitting the frequency band with a true high-pass and a low-pass crossover. There’s very little overlap between the subwoofer and main speakers around the crossover point, eliminating the unpredictable result of having two different sources reproducing the same frequency band—the range of frequencies below the crossover point but above the lowest frequency the main speakers will reproduce. The combination of the high-pass and low-pass filter lets you decide, by listening, how much of the bass range is reproduced by the subwoofer and how much by the main speakers. If your main speakers have marginal bass quality below 100Hz, use a higher crossover frequency so that the main speakers never operate below 100Hz. Usually, a higher crossover frequency results in a more audible discontinuity at the crossover point. But the CR-1’s extensive controls provide seamless integration even at higher crossover frequencies.”
