Average cost of sound system in roller skating rink?

Answer 1

Single, center-mounted array would be the best. So all the speakers hang in the middle of the room and face outwards. Line array would be the best option.

Place the subs in the corners of the room. We call it loading. So four corners then at least four subs, one in each corner. Might need more if you want more bass/low end.

Another cost would be treating the room so that the sound doesn't echo. Carpets on the walls etc. You don't want the sound echoing.

NB: Rather treat a room properly first time and build up the sound system. You don't need speakers everywhere as that's costly. In this application a center mounted array 9/10 times will be the best.

Some companies will try sell you loads of speakers as this equals more profit. Go for a company that doesn't try sell you all their stock.
