Hello,
That is like a mechanic saying you have squeaky breaks but not tell you how to fix them. He could have done a near field test to make sure one speaker is not hotter than the other on its own or swapped the speakers to see if it is the speaker or the electronics. You can test that yourself with an SPL app on your phone and stream 1khz pink or brown noise. Once you narrow it down to the speaker or component you can address that issue. It might be as easy as adjusting the output bias on the amp with a voltage meter. IF YOU ARE NOT FAMILIAR PLEASE FIND A PROFESSIONAL TO SET THAT FOR YOU. Capacitors can change and you need to recalibrate. Start with swapping the right and left interconnects from a source to see if it is on one channel and not the speakers while using the SPL App. Always room treatment before DSP. If it isn’t any of your equipment or speakers it means it’s the room. If you can play with speaker setup. 1/4” at a time. Wilson has been studying this for a while. If your speakers are rear ported you might need defusers behind your speakers or on the back wall. 1. Find out if it’s the room, speakers, or the electronics. 2. Address that issue as stated above
3. Always room treatment and or speaker placement before DSP. I hope this helped because I know your sound engineer did not.
