Is Phantom I 105db that different from current models and upgrades?

The Sonos will be voiced differently and it may well have an ‘enhanced’ base which it more apparent at lower volumes, a bit like the ‘loud’ button on an amplifier. I am assuming you have your Phantoms on dedicated speaker stands? Doesn’t have to be the Tree but something that is roughly the same height and also roughly have the same surface area as the Tree.
