Acoustic Treatment for Pilates Studio

I need a skilled professional to reduce echo in my large open-space pilates studio. The echo is primarily caused by the large open space, and hard surfaces all around. I guess the microphone is getting feedback!

We have the following audio system: https://audioinstallations.co.uk/12-x-5-25-inch-white-commercial-pendant-speaker-system/
