Main A and B (1 Viewer)

[Allen Marshall]

what happens to the watts when you have 2 sets of mains?

 

[John Garcia]

Impedence goes down and current draw goes up, based on the nominal impedence and power draw of the two pairs of speakers.

Wattage will rise, but how much depends on the capabilities/quality of the amp. A higher quality amp will "double down" or double it's output with 1/2 the impedence, but since now have less available current, you are pushing the amp much harder and leaving less room for transient peaks.

If your receiver has a place for an A and B set of speakers, they are not meant to be used at the same time. If you do have both on you will only get half power to each.

since theaters have alot of speakers, do they split up watts for each speaker for 5.1 channels or do they have an amp to power every single speaker by itself.
