Hi Kevin,
Sorry for the inconvenience.
Please follow the steps from the screenshot below to Slow Down Testimonial Carousel.

However, we have listed this in our theme update list. We will add an option to adjust Testimonial Carousel speed in our next update of the theme.
Please don’t forget to give us ‘rating and review’ (on https://themeforest.net/downloads ), if you like our Theme and our support too. It will give us inspiration and make us more ‘happy’ to support.
Best Regards,
ThemeLooks Support Team
