the speech did not go down well with the audience
If something 'goes down well' it suggests that it was met by approval or that others reacted to it in a positive way. A speech or talk can 'go down well' if it was a success and even a meal can 'go down well'. If something 'doesn't go down well', it is met with disapproval or a negative reaction from others. This is an informal expression.
