The general recommendation is to use all identical speakers for SACD
multichannels though I wonder why you need full range for the rear or
center.

Because some artists/mixing engineers like to put full-range material in
those channels too.

Anyhow, depending on your budget. Top priority is front
channel followed by the Center. Get a good subwoofer with volume and
crossover at cut off point of 120hz.

Better yet, a variable crossover. Variable phase adjustment
is nice to have too.
