Thanks for the response. I need a little clarification, please.
What is POS, google says Point Of Sale?
Are you saying that there is a single driver in the speaker anyway?
The 40hz thing, don't know (is there a way to test this?) but the bass is awesome far superior to any laptop speaker I have heard before. The depth of bass doesn't come from the speaker alone but the fact that it uses surfaces it is in contact with to resonate the bass tones. They are pretty awesome sound wise specifically the bass they deliver and impressively portable, even pocket-able, which has specific appeal to me as I will be couch-surfing around Spain on Rollerblades for the foreseeable future.
Peace,
