power amp/pre-amp question

[blacklabel0730]

I am building the 4pi with dual flanking subs and 2pi for surround. Would this set up work well?

Marantz AV7005 Pre-Amp Processor 7.2
with
dual mono block 200w Emotiva for L and R front speakers
5x200 Emotiva power amp for subs and surround

I would run both subs on the power amp with the channels connected to the sub 1 and sub 2 and run 2 more channels for the surrounds L and R

I can choose crossover frequency's for all channels and plan to set the crossover freq. for the subs using this method instead of low pass crossovers.

My question is, is this a good idea? If not, how should I set this up? I am looking to spend 4K max to power these speakers (if I don't have to spend 4K I will be happy). I am using this system for both stereo and movies.

and the subs are passive

Should be fine


It's essentially what I run for amps except the subs run off a Crown XLS1000 with everything else powered from a Parasound 5250.
