Players can define their Min and Max for Bass/Treble through minTreble/MaxTreble (See Player::Boom.pm)... These values are passed to the Player settings menu in Buttons::Settings. But in player.html, the sliders are hardcoded -23 to 23. This is the part of LMS / Perl ToolKit that I know the least so I'm not sure how to change that so that min/max values are honored
