Charlie,

I'm afraid not many speakers fall into the 12dB low frequency acoustic rolloff you used as an example above (except for THX certified and some acoustic suspension or sealed speakers).

This is primarily my biggest complaint with most bass management, especially when they don't give you enough optional xover selections.

Most of the bass reflex speakers are going to have 18dB to 36dB acoustic low frequency rolloffs.

Combine the speakers acoustic rolloff with the prepro's 12dB high pass electrical xover and it will be impossible to get a 24dB high-pass combination to smoothly match the prepro's 24dB electrical low-pass xover.

This is one of the primary dilemmas of less flexible bass management.
