Why is a front system always recommended?

Why is a front system always receptive? Moin people, I wanted to ask why everyone always recommends a front system. Now it will surely come back, that it is too dangerous in an unfsall. Or you don’t stand at the concert with your back to the stage. But you can also fix the rear shelf properly and then something like that no longer happen. And if you still install LS at the front of the rear shelf, is that again stupid with the concert or? Are there no better arguments than the above? Questions about questions
