I've been researching subs lately and noted that some manufactures are able to get into 18, 16 or lower Hz for their subs, yet have the same size drivers as those who can only get to 25Hz or so. Is it mostly a factor of the size of the enclosure, or is it the digital processor and amplification? I'm sure its a combination of the above and more. Any technical help here?
Second question. Is there really a difference between 16Hz and 22Hz that one can discern? Or is it similar to high-end that once you reach a certain level, there really isn’t that much value perceived, as we simply can not hear such frequencies.
