It may be just fine. It all depends on how much time you're going ot have.
You may start with all the subs positioned in your best case scenario idea, ... whatever that is. Measure, and see where that gets you. Perhaps as you (or someone) mentioned, an array lined up across the front as one group, and two in the rear flanking the LP (essentially under the side surrounds) as the second controllable group.
Or, if you had plenty of time, you may experiment with just two subs. Each sub representing one sub group, and just experiment away with the subsequent result. I've used the big furniture sliders with much luck performing these very tasks.
The cool benefit to spaced multiples (especially as many as eight
), is the native response will very likely possess a smoothness over over that of a single or duals. I'd first approach it with some time/signal alignment aligning the two sources, assuring a positive acoustic summation, then EQ globally as a group. Then, whatever method you already prefer for blending with your mains and your all set.
After all is set, you can fine tune the final response by small adjustments in both time alignment/delay, and also some adjustment of low-pass filtering of of each group. It's interesting how each adjustable parameter interacts with the final response somewhat differently. You can establish a max acoustic summation baseline, and then experiment. EQ globally, time align individually.
All this depends on what tools you'll be using, and how much manipulation is nessesary.

Wow, I don't know about that. But I can't imagine a static magnetic field, even a cabinet's distance away from a hard drive could do anay damage. Hard drives, and the magnetic data therein, are a lot more robust than many of us give them credit for. By design, they're really well protected from stray magnetic fields. Typically the environments they're used in are heavily laden with stray fields from varying sources. Hell, both the motor spinning the assembly generates a magnetic field, the stylus arm head, for writing and reading, generates a strong magnetic field.
I wouldn't think it could be an issue because of the inverse/square law diminishes the strength of the permanent motor magnet so much, relative to the powerful head assembly neo magnets right near the platters.
Have fun with the project ... love those flat packs
