That is the latest curve I tried. I suppose it could be improved. I set the Porsche settings at +6 for bass. The result is it's a TON more listenable. The 991 Bose system is a disaster compared to the 997 Bose system. And the 997 was just OK. Using this much bass boost there are limits to how loud you can play music, so listen for the bass drivers breaking up or distortion or you could damage a bass drivers. Distortion means back off the volume. But it plays plenty loud for me with the top up. Top down who cares.

 

 

I think you will be surprised. Equalization can do amazing things. At Upscale audio we DON'T use EQ. We even avoid tone controls. But in my cars this has worked wonders. I don't mind spending money on my Porsche but frankly I'm not super keen on having it taken apart. I'm a freak about rattles and squeaks.

 

 

Seeing how a lot of shops butcher stuff I don't think it's really worth it.

 

 

TQP: AI Design? They are definitely the best around these parts but, I wasn't feeling it with them. I met with them and the price was high, but artificially so IMO. Didnt want to lose Frunk space and they weren't interested in other options like under the passenger seat. No question they are good, I just decided to travel 200 miles each way to MA to get it done. Big improvement over stock Bose dont you think?

 

Did you try the EQ app yet? How did it work out?

 

i have not - have not had the car out of the garage ;( . should be able to this weekend.

 

AI is correct. I always believe that you get what you pay for. AI only took up a small area in my trunk and build a shelf over it. Everything looks stock. Big improvement over Burmester (Mercedes Benz) and just about any other car audio although the B&O in my Audi SQ5 is pretty good. I keep saying junk in junk out. Tidal or digital/DTS sound makes a huge difference.

 

 

sorry... i can't hear you... the windows are down and the sports exhaust is on...

 

I had a professor that studied at MIT with Amar Bose, the founder of the Bose Corporation. He was so enamored with Mr. Bose that he chose the textbook for our course that year to be one that was authored by Bose himself.

Throughout the year, our coursework included audio/electrical problems that my professor had encountered while working with Bose. Our school was not in the same league as MIT, so the class tended to boo and hiss whenever our professor sounded-off with anecdotes of Bose and his work – all in good fun of course.

I came away from that school year, in the days before the Internet and do-everything smartphone apps, thinking that Amar Bose was one very sharp cookie so to speak. He designed using a pencil and paper and engineering first principles – no catalog lookup or app settings for him. Mr. Bose and his company are an American engineering success story.

I chose the Burmester over Bose for my Porsche last year because it sounded better to my layman's ear. But, I could never refer to the Bose system as junk or crap.

 

 

Bose is just branding and marketing. It in no way implies quality across the board or some level of superiority.
For all we know the parts are made in China and rebranded here in the US. No idea, just speculating.

I can tell you from personal experience that after inspecting the quality of the speakers, the materials used in the production and the sound, that the Bose in the 991.2 is low end from any perspective.

Even the worst, least expensive aftermarket parts from Crutchfield are of higher quality than the Bose stuff. The advantage the Bose system has is that it was designed into the car so it sounds better than it should because you are flooded with sound from all over the place (front/rear/dash/sub) but, the sound itself is caca.
