Allah's loudspeakers

In a Muslim country, you expect loudspeakers on minarets, for the prayer calls. But in Indonesia, you also find loudspeakers on the rooftops of prayer houses (mushola), and these proximity prayer houses are nearly everywhere. A good thing, people would say, since you don't have a long way to go for prayer. But then, if it is so convenient to go, what is the point of the loudspeaker sending not only the calls, but also whole prayer sessions and Holy Book recitations? So close and so loud that you have the feeling that it is in your house. So why going?
