Product page has X overs listed at 500 & 2 kHz, so it looks like the 6.5" driver is crossed at 500.

@Brendo - hope this is helping your original question. I have no experience with height speakers so can't comment on that, however as surrounds the QS series (QS8's in my experience) are awesome in 'traditional' 5.1 to 7.2 setups.
