[QUOTE="Ampdog, post: 34962, member: 144"] Is the sub used to 'augment', i.e. your normal two channel loudspeakers are also going right down? Then you have simply changed the phase to give a 'better' room response at your seat. There are always standing waves in any room at low frequencies. Also, with two channels or 'extra' sub, you will get cancellation of bass at certain frequencies and augmentation at others. Why was it different (satisfactory) before? That is a little more difficult. Has something been moved in the room? At low frequencies room response is not as dependent on furniture placement as on loudspeaker(s) position. It might be quite illuminating if members would try reversing the phase of one channel - this is mainly for stereo, not multichannel.. One is very 'sold' on correct phasing, but have you ever listened to one channel reversed? If you could have someone else make the change while you are in several listening positions, you might find a few surprises. [/QUOTE]
