My JL Audio F112 sub also has a soft hum but it can only be heard with the ear near it. Accidentally I once found out it lowers in volume when I ‘shield’ the side e.g. using a piece of aluminium foil so it’s somehow sensitive to outside RFI. Nothing to worry about, I agree with Martyn; we’re spoilt with our dead silent Devialets!
Enjoy!
