This is because REL are designed to produce deep bass.

What Volume Should A Subwoofer Be Set At?

Set the analog one with a rotating knob to the middle of its range.

For most watches, this is at 12 or 1 o’clock. If it’s digital, the control could be in an app from the maker. Start in the middle of its range as well.

If your SVS subwoofer has a digital volume control, set it to -15 to begin with.
