Oh look at that... They changed the layout. This is the link I used to get to the this forum.

https://rennlist.com/forums/987-981--718-forum-125/

Notice it used to include 718 but now redirects to here with no 718...sorry everyone!

It's a pretty recent change.

Does the sound from the PSE make much difference between the BS or BGTS?

I assume the sound is the same on both when fitted with the PSE.

Has anyone tried both back to back?

So you can confirm that it's not a "speaker" on the 718 GTS? That's the actual question. It's common knowledge at this point that the "acoustic channel" on the 981 GTS models isn't a speaker, but this is the 718 we're talking about.

So, it is and it isn't. Quantifiably, the GTS has a "symposer" which apparently is a new word invented by Porsche or Subaru that means "not a speaker". From what I understand, the S and base do not have said symposer... so they do not sound the same, PSE or no.

From outside I don't think there's a difference but truth be told I've never driven a 981 S with or without PSE.

There's also the theory that that's where the "VTEC kicks in".

No, seriously, I noticed a super slight hesitation right about there at light throttle, and a kick in the *** there at full throttle. Might have something to do with it. I did a search and yeah, that seems to be the consensus for when the cams switch over.

I'll see your suggestion to google something and raise you an actual link (to another forum... that references the 718 technical manual): http://www.planet-9.com/718-chat/177...-actuator.html

Relevant text extracted from that post:

"In addition to the new exhaust systems, an electric sound actuator is responsible for creating a sporty Porsche-specific sound in the passenger compartment of the vehicle. The electric sound actuator is installed on the front engine cover in the passenger compartment. It is activated by way of a separate control unit connected with the CAN bus. This control unit is located at the rear left of the luggage compartment.
Electric sound actuator 2_24_17
The goal of the sound actuator is to support/enrich the engine-specific sound, whereby the acoustic component of the sound actuator should harmonize with the sound of the engine and exhaust system depending on load, engine speed and driving speed."

I've read that article you reference, and I tried to be specific in suggesting that we weren't talking about the 981. The 718 has the "soundaktor" that's mentioned in that very article that first showed in the GTI. It is apparently a speaker.

Man, the purists couldn't be more offended if Porsche tried. Fake Porsche engine AND fake sound? The travesty!

You're so dramatic.

Like I suggest to everyone else; take away the comparison to previous gen models and any hurt feelings you may have about "a $100k 4-cylinder", and is the sound really THAT bad?

Most reasonable people would agree it is not.

Back on topic, I personally have zero issue with added sound, be it natural or artificial. My wife's Macan actually sounds pretty damn great from the outside... but you can hear nothing from the inside. It pretty much prevents me from using the PDK in manual mode. I wouldn't mind a little extra aural feedback while still enjoying the relative silence inside the cabin. And I'm still trying to figure out what exactly is being compromised? Even with completely artificial sound being added from a recording... I think the consensus is even among the vocal "purists", that it's not that the sounds are "bad", it's the principal of it being artificial. Is that really what all the fuss is about?

That's pretty much a rhetorical question but I'm still trying to get a handle on why people feel so strongly about this.

Firstly, I agree with you. Having driven the 718 and 718S I don't think they sound horrible. Having owned a 981 Boxster GTS, I can conclusively say they don't sound remotely as good, but then again, very few things do.

On their own merits, they sound fine. While driving them, even on a track, I never thought "Man, that sounds bad". I also never thought "OMG this sounds really good!!" It is what it is. People who don't know better should rightly love the way they sound.

As for the next part... if you're playing sounds through a speaker, you're faking it. That's all there is to it. I think it's stupid. Beautifully sounding engines enthrall us. You can't fake that and pretend it's the same thing. I'm quite ok with tubes and baffles and anything else they do to manipulate the sound. I'm not ok with just playing sounds through the speakers.

Finally... if they ARE gonna do that... I want it configurable. I want to switch it from GT3RS flat six to Hellcat V8 to Ferrari V8 to whatever the hell that sound is that the Jetson's cars made. I mean why not have some fun with it? If you're going to play fake sounds, let's not try to pretend it can only make that one sound you've chosen. Let us choose.

Bentley GT's fabricate(d) the sound as well. Stupid.

I agree, for the most part. My BMW is a good example of this. It's built and insulated very well. The extra aural feedback is great. Keep out the road and tire noise while still giving me information about how the engine is working. I guarantee precisely no average person would have any idea it was not the actual engine noise unless told so. My wife refused to believe me when I told her!

You can code a BWM to do that. Well, not that extensively, but within the BMW family. You can code it off or to an M3, M4, X5M, etc. I haven't done that.
