Wilson Audio Sasha sound imbalance

I replaced the resistors, and the imbalance exist.
Its really in the vocal area more then anywhere else.
Eg: The centre image for instruments such as drums comes in the centre but vocals seem a tad off to the right.

Anything I can do to test the drivers?

Hi All, 

I have now testing the tweeter independent of the midrange  and noticed that when the Midrange is only connected the image is dead centre.
That's not the case with the tweeter only connected.
The vocal image is slightly to the right, believe this concludes that the left tweeter might be faulty?

A wavering center image in my experience has always been solved by more precise setup of speakers. Double and triple check your measurements as well as toe-in. The fact that it wavers only in a certain band strongly suggests to me it isn't a balance issue.

I mean no disrespect but if you read my posts earlier I have advised that initially I tested swapping the WATTs and the image moved to the opposite side.

Did you try the wah-wah test?

I haven’t didn’t really understand the instructions. Can you dumb it down for me?

thanks for the detailed posts, really appreciate it.
To answer some of the questions:
I have swapped the resistors to new ones.
My source is a turntable only, a while back I had to solder one of the tonearm channel wires but that should not have any impact as I mention the image is 20 degrees to the right in the current state, when I swap the WATT speakers the image moves 20 degrees to the left.
This tells me everything up to the speakers in the chain is working fine.
I have got my local Wilson Audio dealer to get in touch with Wilson Audio, let’s see what they come back with.
