Apparently if you look at Infiniti's web site, as Wiggum posted above, they seem to mistake them for sub-woofers as well. Or at least they falsely advertise them as such.

Maybe one day somebody will file a class-action lawsuit and we can all get a check for $2.29 for being misled.

 

I guess it depends on your definition of sub-woofer. These woofers are a dedicated component with their own amp and filtered to produce low frequencies.. that more then meets websters dictionary.

That's not quite enought to meet what most of us would consider a sub-woofer however, that being able to produce audio frequencies that can extend to the lower range of human hearing and rock your world.

 

Technically a "SubWoofer" is meant to, and can reproduce frequencies below 80Hz. The 10" Woofers in the doors, dont even come close.
I am speaking of a coupe, the sedan has a 15" in the package tray.
