UPDATE:
In the meantime it has been officially mentioned in press texts by Ford that they use a system called "Electronic Sound Enhancement" (ESE) similar to the Ecoboost models also for the GT versions.
This is confirmed for the cars with the B&O system, other ones I'm not sure about.
The sounds are kind of subtle until you first really identified them and artificial, so not actual sound picked up by mics from the engine bay or near the exhaust tips (also, there are no microphones in these areas).
They interfere especially with the subwoofer signal at low RPM. Then the frequencies of the generated sound are accordingly low and played through the subwoofer to mimic a deeper rumble.
This leads to weak and imprecise punchless subwofer performance and, if the sub is upgraded with a separate amp, it can lead to louder drones or buzz tones.
Confimred by a couple of users with car stereo upgrades on this forum as well.
I measured a dominant 46 Hz tone once I started the engine with ESE on, and with it turned off, that tone was gone.
Good demonstrations of how it works can be watched here (to really get it, headphones are recommended):
1) A tuning company found by accident a developer mode to play the "enhancement" sounds without the engine running:
2) Some other guy took some comparison videos with ESE on/off driving a Raptor:
The good news is: This system can be turned off with Forscan:
In module ACM you have to change whatever character you have in the third column of the following line to zero:
727-01-01 xxxx xxxx 0x--
Checkout the Forscan sub to learn more about it.
If you do not know if the system is turned on or off on your car and want to check it without having to use Forscan, you can visit:
https://www.motorcraftservice.com/AsBuilt
and enter your VIN.
Once the website has finished loading, it will show a very long table with lots of setup parameters of your individual car. No need to download any files if you are not planning on using Forscan.
Search for the above mentioned line 727-01-01 and check whether the third column starts with a 1 or a 0. 1 means ESE is on, 0 means it is turned off.
Ps: This thread was hijacked by some brainless NPC who does everything he can to question the existence of ESE and throws in the same stupid questions and claims all other must be wrong over and over again, so more or less all pages following my first post on how ESE works (page 3) are repetitive explanations to those who came late to this thread without reading previous pages but were actually interested without fighting evidence.
But wherever possible, Mr. "I was ran over by a train, but miraculously the 5 braincells necessary to post weird troll one liners survived" really destroyed the conversation.
However, the main question has been answered above together with the description of how to turn off any artificial "sound enhancement".

Original post with answers:
I wonder if the GT also has the same fake engine/exhaust sound playing through the speakers?
1) Does it? -> Yes
2) Which speakers are used when having the B&O with subwoofer? -> Frequency dependent, sub for lows, others for increasing frequencies
3) Can it be disabled and if, how? Especially on convertible -> With Forscan, explanation above, valid also for Fastback
Would be really shocked if Ford had put it in a V8.
