The 8-pole filters are described as having "a nominal 0 offset" and do not need to be matched for diversity. However, my 400Hz 8-poles are offset by as much at 80Hz. The ordering page doesn't provide for matching 8-pole filters. This is only an issue for the narrow filters and only if the offset delta between the two filters is greater than 10-20Hz. If two 8-pole filters are offset, say, +60Hz and +80Hz, then you configure both for an offset of +70Hz and will be fine for diversity receive.
