Stock Subwoofer?

I was on Toyota.com just messing around making tacomas and stuff and I came across the TRD Offroad Package/ JBL thing, never saw it before I clicked it. It has 6 speakers and a subwoofer.
Is it really like a subwoofer that comes with the package?

 

I have a 09 with a 7-speaker factory stereo. It is not JBL. It does have a sub. It is located on the back wall between the two rear seats on my Access Cab. It is not a real sub as most would think but either a 5x7 or 6x9 woofer. It sounds ok but looking back it was stupid buying. (FWIW - It has been replaced already due to "rattling". I replaced the factory head with aftermarket but I am still using factory speakers.)
