Gave up bass he didn't need (because he added the subs) to optimize imaging. Perfect. Expensive, but perfect.
I thought all serious audiophiles did that these days? It's not just a question of "giving up bass he didn't need"; without at least one sub supplementing even "full-range" mains you will have at least one significant null in the sub-200 Hz region unless your room is huge. And it's a rare room where the speaker placement for best imaging will match that for best bass response.
