"Hum" instead of "Boom"

What first noticed when the package arrived with the Yamaha: pretty big. The impression remained even after unpacking. Should ;-) order of appearance, the installation will therefore provide ample space. Who would establish how often recommend two of this woofer, then you need lots of it ... all right ... Another tip is therefore to clarify itself absolutely before buying again, the dimensions of the truncated pyramid.

But it is (of course) not the size that leads to a two-star rating, but the fact that the subwoofer low frequency hums to himself as soon as he is put into operation. And that does not stop even to off. It seems he could not care less if ever a signal source is connected (external interference can hardly be's). When listening distances greater than five meters may no longer worthy to be that, but including it interferes significantly. Finally, a series of films and songs have a few passages without (deep) Bass. At these locations a subwoofer you should not listen up. Whether the phenomenon is an exception for this one device? I do not know, the sonic impression when he aufspielte because was not convincing enough to want to find out via device replacement yet. This does not mean / need: the subwoofer sounds bad when Bass production, but only: subjectively heard not good enough to concede the series a second chance.
