    Hello Rusty

    It's a weird shaped room with a large walk in closet filling one corner. One speaker is close but better the other has no wall close. There is no way to get symmetry with placement...

    I don't think you need DSP just use the original passive compensation in bi-amp mode. Look at the polars!

    I wouldn't jump to any conclusions. Those 2216's are quite capable. The 2234's may win an SPL contest but I doubt they will sound better in the upper part of the range.

    It's a 2 1/2 way so both woofers share the same range from say 200hz and lower. The 4435 is a single shared box just like Everest. You really don't need 2 2216's unless it's a huge space.

    I agree but it looks odd. Where is the black wire connected?? Almost looks like a jumper has been cut out. What are the "green" things? Wonder what the back looks like?
