help me pick an active crossover.

I'm looking for A crossover that i could use to not only bi amp my main, but that would also give me a sub out and a subsonic filter, I would also like those filters to be more than 12db. 18 db is ok 24 would be cool, and a programmable one like the ultra drive would be even better. But there is always the cost deal. So here are some ideas and i want to know what ya'all think.
First up... Peavey XD3/4
My only deal is that on page three the manual is says that the subsonic is 40 hz 12db and in the specifications on page 6 it says that it's 18 db... so what is it?

There is also the DOD834, I have never heard of them, maybe i have just been in a closet or something, but here's the specs:

Last is the peavey CEX 4la..... i think that i would need two of them. However I would then gain the ability to have a limiter, add time delay, and I thought i read something about an EQ. Maybe just some tone control?

Take a look at the Behringer DCX-2496, it offers some great options including per channel limiters. It has three inputs and six outputs. You can have 48db slope on the filters, mono sub output, and complete control over LPF and HPF per output.

Well i went for two of the Peavey CEX 4LA's.
I'm really excited to get my cabs built and to bi amp them.
I am also excited to use the delay feature in there, but how do i know i have it right? Where do i start? Do i need to delay the piezo arrays however far the tuba horn is? And how about the beta 8 in the dr?
Thanks for the help.
