Reduce The Height Of Slideshow (Dawn Theme)

[BraxtonEcom]

Is there any way I can reduce the height of the slideshow so that it's the size of what I've drawn on the attached image?

I'd it to be like this on all device viewings e.g. desktop, mobile, tablet..

Any advice is appreciated

I'd like it to be more like the testimonial slideshow on this website:
