even flat to 30hz is impossible with a 6 inch if the cabinet is small. the amount of distortion for a 6 inch to do even 30hz at 90db will be enormous.
If you think it's some alchemy, take a look over PMC AML speaker. They used Nomex 6 inch LF driver and its goes down to 33 hz at - 3 db. I'm not so sure but maybe PMC are the first one that supposed to invent such a technology and fit this low frequency range into a small box. Yes, it could be artificial but it's real and usable according to David's impressions with PMC AML 2.
