this subwoofer is a looker pure. So if you stress with "woman" have then thyself there disese part. Possession of it for about 3 years and operate it together with Canton speakers (5.1). Would also prefer not suitable ns-f 700 chain but at the moment I do not want to change. It has been above 2 keys and 2 controllers. A button for Standby / On. Either permanently or through your AV receiver controlled if necessary. Turns with automatically, so to speak, when it is needed. A key for Bass. It is even adjustable for music or movies. For me it is always on Movie. Music I listen to stereo without a subwoofer. But you can try it music, when you might have no tower speaker but Kompaklautsprecher. Since you could use this setting. A controller for volume. In my Onkyo 3007 is automatically calibrated and controlled, so it is at max. A controller for High Cut. (40-140Hz). Ie you can adjust will depend how much Hz to the subwoofer connected with. For me it is at 40Hz, because the Onkyo does Calibrating this setting himself. I think this makes calibration at the moment almost every AV receiver. From the sound of it I really like. Of course that depends on many factors and everyone hears differently. One problem is also the space. I have unfortunately not an ideal living room for a good sound. But the calibration brings out the maximum quality. Movies are an experience I can only say. Processing 1A. Piano lacquer looks very classy ..
