I have engineered speakers for almost 40 years. Resonance, vibrations, absorption and the transfer of these has been a field of study, along with aerodynamics and siesmology.
I "get" bass bridges. Some of the "tech" is simply incorrect too.

But it IS about getting high and consistent pressure from the string break point to the body.
Which leads me to the stock Sire bridge. After removing it, I realized it is better than Amazon bridges which look very similar for less than $15.
It is heavy. Maybe as heavy as some high mass bridges. The ridges for slight string adjustment side to side are a nice touch. But there's two issues. One is a workable, but poor design. The very design wants two screw tips per saddle to transfer all of the energy to the body. Not good for this purpose. In the photos you can see where they ground down the bottom of the bridge, where the stamp made channels on top for the screws. They didn't grind the bottom flat as you can see. But they left untouched places, and poorly ground other places. This makes a poor connection with the body, compared to a flat bottom.
Also where the screws touch have been shown with red. These are all that transfers the energy in this design. And lastly ... those screws. We studied screws and bolts a lot in college. They vibrate at a certain frequency, which changes with a lot of variables. These vibrations ARE transferred to the pickups, amp, and overall tone of your bass.
Aaaand I said all of this, to explain the next point. I lost the somewhat irritating, honky mid sound by changing to the Babicz bridge. It definitely shifted the tone of the bass lower and more solid sounding. Rhe tone comes through more pure. Less mid centric.
