I have a pair of LSR32 that are not mirror imaged: the two mid/tweeter panels are the same, with the port or the right and the drivers on the left.
I thought about ordering a complementary panel, but the spec sheet is not really clear to say the least, as I have no way to know if the one I have is supposed to be a left or right panel...
Logically that would be a left panel when the speaker is used in the vertical position, and a right one when used in the horizontal position... Oh well...
Anyways, if someone is in the opposite situation as me (ie two identical panels with the ports on the left), then we could make a swap...
