I'm surprised nobody corrected Holly Bush's (incorrect) assertion that the NXT speaker is an option and not standard. The statement clearly says it is the STANDARD. It is the other 8- or 9-speaker options that are non-standard (as they would be).
Extract:
"The robust interior is completed with the addition of the NXT-based roof liner loudspeaker system which complements the FJ Cruiser's conventional speakers to create a broad, omni-directional dispersion of high quality sound that fills the cabin and envelopes passengers.
The vehicle is available with a choice of three audio systems, with an AM/FM/CD system with six speakers fitted as standard (including NXT-based roof liner).
The other options include an eight speaker system with six-disc CD changer and a nine speaker system, complete with subwoofer."
