This was really bugging me, so I dug into Photoshop and did some experimenting. If we assume that the transformer is mounted upright (not lying flat), similar to the way that Outlaw mounts the dual toroidal transformers in the 7500 and 7700, then the width of the enclosure would be equal to or very similar to the height of the enclosure. Cropping all of the images (front, back, and top) to just the exact width of the unit (no more than a few pixels of white space to the sides) and resizing to 1000 pixels wide gives us a common scale for all three images. With this done, the width of the transformer enclosure is 410 pixels (just over 40% of the width). That's six pixels less than the height of the cropped and resized front panel image and two pixels less than the height of the cropped and resized rear panel image. Based on that, it would appear that there is a toroid - the cover and the depth of the chassis just make it hard to tell. I'd guess that the toroid is about 6" in diameter and probably 3" or so tall. I e-mailed Emotiva earlier this morning to get their input. They should be able to confirm this (three earlier e-mails relating to the LMC-1 have gone unanswered over the last month, but hopefully this will be a simpler thing to reply to).
