While I have personally not heard the Moabs, I heard their mid-range response was … less than stellar.. If I could have afforded the Encores, I probably would have got those. But my DI/SE sounds really good. Both have actual mid range drivers in addition to the arrays.
my maggie 1.7i do not handle bass as well. Currently have a pair of the Tekton 2-10 subs working with the 1.7i pair and this works well… until the maggies start to have weird sounds in the bass.. thinking of high passing those from 100hz at the amp input, 12db drop, and raising sub freq up to match.
