I want to buy this product, but first I would like to know which kind of power supply does this subwoofer use. Is it a switced-mode power supply, or a standard transformer one?  I don't want transformer PSU in my subwoofer because they tend to produce a noticeable 50Hz power-line induced hum (because the transformer itself vibrates and I can hear it no matter how silent it is). I have a very sensitive hearing and this kind of hum drives me nuts.

Old but I have the same problem with my Temblor T8. After one month I had a loud hum. This was in around 2016. They fixed it and it was good for nearly 5 years. Now it hums again. So I think it is a 50Hz standard transformer.
