Which Speaker System ?

Shameless plug for something I currently have for sale but if you need to run two subs and your preamp only has output for one, then a JL Audio CR-1 crossover (along with a few others) is what you need. If you don’t have your subs already, I do highly recommend JL Audio subs. I have had and still own 2 Rel subs and an M&K sub but the JL Audio subs are better (F112v2). With the crossover, you don't have to limit your preamp search to only those with two subwoofer outputs, any preamp with one subwoofer output will work, which is the majority of them out there.

Another question.  I am considering running 'phantom' mode for the center and elimininating the Center speaker.  Have you tried this?

There are those that say if you have good left/rights and a good quality receiver with an excellent 'phantom' mode that you don't miss the center speaker.

Phantom center is great for the one who sits in the center line with the video screen , not so good for everyone else.

Makes sense

I received the Palladiums, P37F, last night.  I'm impressed!  Are they as good as my reference Magnepan 20.7's; no.  But they sound pretty darn good!  And they will work much better as an excellent home theater speaker.  

I only bought two of the rears (P27's).  Do you have a perference for 5.1 setup vs 7.1?  Perhaps I should get two additional rears.
