Putting the manifolds and plumbing right next to your back in the tub IMO makes them noisier than others.

I first thought it was the jet pack... swapped them around and it didn't change. Opened up the equipment bay to investigate and found that one of the air inlet hoses had found it's way to a spot up against the shell and was making a noise that was transmitting outside. Moved it a couple inches away and all was fine. Point being, that little hose sucking some air inside the cabinet was louder than any perceived noise from the jetpacks or manifolds.Your logic seems reasonable. Maybe if you had them to test side by side you might be able to perceive that. But in testing different brands at different locations, we never noticed it as an issue at all. Our Bullfrog is also much quieter than our old Dimension One that only had 15 jets in it. But all newer hot tubs are quieter than the old ones because they've improved the pumps. That's where most of the noise comes from.

So your comparison photo used a Calspa? How many jets did that Calspa have if that's what your saying/implying?I didn't hear it mentioned and don't like to assume.

Cal spa was the only decent one I could find to show "others" how a conventional spa is built. And how much plumbing goes in on one. Sad thing is, that still doesn't show really how much plumbing there is on any given spa. Like Jacuzzi, Sundance or any other spa for that matter except Bullfrog. In the end it doesn't really matter what spa it is in the picture, but it gives the consumer the visual of how a conventional spa is built. And if you can't agree on that then you do not know as much as you think you know about how one is put together. 90% less plumbing or not Bullfrog still uses way way less plumbing than any other spa.
You are like trying to tell a liberal why Hillary or Bernie shouldn't be president.
Instead of splitting the water flow after the pump and then directing through hoses to the individual jets. Bullfrog splits the water flow behind the jet pacs and sends it to the individual jets. It's plumbing. Plumbing creates water cavitation. Water cavitation makes noise.
