I think we all make too much of an issue with the crossover frequencies for these units. For one, the crossover needs to be the same for all speakers to prevent phase problems. Two, as long as all of your speakers will play down to at least 110hz, although lower would be better, you'll be fine. Sony with the BDP-S5000ES have figured out a way to make this player really shine with True DolbyHD and DTS-MA, the new audio surround cedecs. I'm certain Pioneer has done the same with the '09. Giving out the exact frequency response may be a trade secret for these companies.
