JBL GTO's you will get here are going to be chinese.
Check where they were originally made for. Matlab for which country to be imported to.
Like I have Chinese Pioneer TS-6975s. They sound as good as any old Japanese 715's. Got em for 7,500. Reason they are good ... it is actually for Belgium. Says so in the bottom strip.
Go to a good shop ... and just ask them to test both. They will do that!
718 Malaysia for 4,500
GTO 936e for 5,000 ... Chinese I guess.
