I installed the iPhone 7 plus speaker sample I got a couple of days ago, into one of the Athearn SD40's that still had the iP4s in it (the wiring to the rear lights had "popped" one of the fans up, so it had to come apart). After trimming the mounting bits off the speaker, it was the same width as the iP6s plus, installed in the other similar loco and slimmer in thickness than the iP4s by about 1.5mm.
Soundwise, comparing it with the iP6s, I couldn't detect any appreciable difference, but I'll ask for opinions at the club as well.
What is most notable with these phone speakers, is the variations in size and shape they come in, even within the same model.
