Hello David12.
You may wish to toe them in quite a bit, do feel free to experiment. This is because I find the ribbon tweeters quite "directional", so actually they do benefit from toeing in greatly. For me I toe them in so that the tweeters just cross slightly behind my head. Also because of the MTM arrangement, if you have enough space, do make sure you are at least 9 feet from the speakers so that the drivers can "integrate".
Maybe you need to space them slightly farther apart than 7 feet, if possible.
