You will find few if any speakers that Soundstage found capable of true high fidelity at 95 dB and above. We agree on that point.
That said the Vivid Giya G2 performs well - this is an example of high fidelity at higher SPL

As far the definition of Decibel you found it. Sound intensity or volume indeed doubles for roughly each 3dB in SPL which is a mathematical certainty due to the formula. Doubling to the perception of the listener is whatever it may be. Perception isn’t what you get from SPL measurements using a sound meter.
