Portable Speakers for Outdoor Movies

15W a channel will be very faint outside, quite a lot more power is likely to be needed, depending on the scale of the audience area.


[ Though I see those have high efficiency, which will help considerably. They lack decent bass being small, and outside its hard to get enough bass without wall reflections anyway. ]

Since they are active ( the amplifier is incorporated) the efficiency data is meaningless. R U serious ?:eek:
No the efficiency data is perfectly useful here. 15W amp and [email protected],1m speakers can go to [email protected]

50W amp and [email protected],1m would only go to [email protected]


The other thing the efficiency data tells is that the cones are thin and light, not the best for outdoor environment where humidity can be high and soften the cones.
