For HIFI apps you can use from 300 Hz - up since you're shelving the driver down so much efficiency wise, so what's your woofer and any particular XO point?
500 Hz was the preferred since it's the ~half acoustic power point of a large orchestra, but assuming a wider range of musical types, not necessarily the best overall choice. Note too that with this much shelving you may not need a super tweeter once CD horn EQ is applied to flatten it.
