you would probably be better off doing 2 columns of 8 12" peerles xls each, 4 really wont give you enough room to get down low at a decent spl. have 4 facing the front and 4 the rear to cancel out all vibrations.
When you model 8 of the subs in a small sealed enclosure of 8cuft you will need 1000watts before you run out of xmax at 10hz. You can use your eq to get a maximum of 116db @ 20hz per tower
If you only use 4 subs per tower, they will only be able to handle a total of 250watts before running out of xmax down low at 10hz. And you will only be able to achieve a maximum spl of 107db @ 20hz
As you can see in these two scenarios, by spending a little more money having double the subwoofers will give you a huge increase in performance. Having a array of eton drivers to begin with, I would assume you would want the best out of your subwoofer array also.
My personal subwoofer arrays consist of 4 ascendant audio atlas 12" subs each which have 18mm xmax. So they would have a similar output levels to 6 of the peerless xls subwoofers. Looking back on the design, I would like more headroom down low. So when I have time to upgrade I will be using at least 8 of whatever 12" driver I decide on.
hope this helps
