In the literature on Paradigm speakers, what does the phrase "Low-Frequency Extension" mean? For example, the Studio 40 has a listed Frequency Response of 62Hz-22kHz +/- 2dB, but with a Low Frequency Extension to 36Hz DIN. What does this mean in plain English? Do I hear sounds, e.g. guitar & bass, down to 36Hz or not?? I've read through their website & brochures and still can't find an answer.
