Both the EP175 and the EP350 will reproduce 20 Hz but, like virtually all sub-woofers of a size that can be acceptable for home use, it will be at a lower volume level than 25Hz or 30Hz. We are going to write a much more comprehensive article on this whole subject for our web site in the near future. For now the short answer is yes they will reproduce 20Hz.
