Mike, your concern about possibly annoying the neighbours is admirable. I like to think that we all are so considerate, which sadly at times is not reciprocated.

But Rob is right - changing the speakers is not necessarily going to be a solution; it's the overall volume level at which they are played.

When you move, introduce yourself to your immediate new neighbours and find out about their lifestyle: if they have small children; if any of them work shifts etc., so you can accommodate it with your listening habits.

The last thing you want is a "loudness war" and to be at loggerheads with the neighbours.
