I have some Castle Harlech speaker and the tweeter is slightly offset to one side. It has been recommended that they are placed on the inside of the two speaker rather than on the outside. As I have an amp which has blown on the RH and it was suspected that one of the faults could be the speaker. I was thinking of swapping them round and if the left sides goes next time it would look highly suspicious it is the speaker. Is there any reason not to swap them round sound wise or any other reason?
