How to beat the acoustics in the gym?

Question

Audio

Is it possible to set the speakers so that there is minimal echo.
The room is a large and high gym, empty. I don't know the sizes.
Speakers can only be placed on the floor, there is a mixer.

Answer 1

It is best, of course, to hang all the walls with carpets. I'm not a professional, but I think it makes sense to place the speaker close to the smaller wall in the middle and direct it along the larger side of the hall so that there is maximum distance from the opposite wall.
Another option is to use a lot of quiet speakers around the perimeter so that the waves from them do not reach the opposite walls.

Answer 2

Any reverb is primarily parallel surfaces with a good sound reflection coefficient. Carpets in the gym are, of course, piquant, but in addition to the methods described above, I would try to place the speakers not at right angles to the walls and ceiling.

Answer 3

I had friends that they set up via the phone. Now the mobile version of the Leon website is available from any phone, on the Android and iOS platforms. Now all users have begun to bet more often from devices.
