It is actually more complicated than we would like - simply because of the checks that need to be made on the value. For example - if it is NOT checked... how do you know it is not checked on purpose by the user -  as opposed to an original default? 

The following is about the only way I can think of doing it safely. The following code assumes that the slug of the custom profile field checkbox is 'magsub'. You can find the actual slug in the CPF creation admin panel.

So - you could put this in the spFunctipns.php file of your SP child theme (in the .templates folder). And change ALL instances of 'magsub' to the real slug. This will ONLY set the default on for the first time it appears in a users profile form.

add_filter('sph_custom_profile_fields_magsub', 'set_default_magsub');
function set_default_magsub($cb) {
    global $spProfileUser;
    $d = spdb_select('row', "SELECT * FROM ".SFUSERMETA." WHERE user_id = ".$spProfileUser->ID." AND meta_key = 'magsub'");
    if (empty($d)) {
        $f = array();
        $f = explode('"checkbox" ', $cb);
        $cb = $f[0] . '"checkbox" checked="checked" ' . $f[1];
    }
    return $cb;
}
