Traditional tower speakers can have anything form 2 to 7 or more individual drivers. Normally thees would all run form one source and be divided up using internal high-pass/low-pass filters. Now if the tower was instead built to accept say 3 or 4 inputs then you would only need 5 of them to get the magical 20 speakers + 2 subs

Good idea, but I believe that 20 channels would need to be spread apart way further than the transducers on a traditional floorstanding speaker. You wouldn't perceive much of a change in the direction of the sound unless they'd be spaced evenly apart .

Setting up 20 speakers and adjusting their room EQ and delay would be a nightmare though.

Well the 5 in one speaker was a bit of an extreme example but I think you could make it work at least with 2 channels per speaker and that would still bring down the number to a much more reasonable 10 cabinets. I mean there is a lot of speakers what have highly controlled directional outputs.

You got multidirectional speakers like this



And omni directional speakers like this




There are also thees virtual surround speaker bars that attempt to create surround sound by bouncing the sound of the walls. (though thees system suck tongue.gif )






I'm just thinking there is got to be a better way to do it besides scattering 20 individual speaker cabinets around a room.

I didn't see power usage specified but don't more pixels mean more power consumption? I am basing my statement on iPad retina. I hope Im wrong though.

There are a lot of other factors as well. Power consumption varies greatly depending on the panel tech and the used backlighting. An TN panel that uses LED's will draw less power then an TN that use CCFL's. AMOLED' s need more power then an ISP ect.

But in the case of the iPad its as much about the power the LCD draws as power draw of the rest of the parts. To run the higher resolution the retina iPads GPU needs to work harder and thus the system draws more power. If we where measuring just the screens power consumption the differences would be smaller.

True however it doesn't change the fact that high density pixel screen requires good hardware which again consumes a lot of energy.

Depends on what type of usage we are talking. If we are talking in the context of screens for tablets, PC etc. that run of generic GPU's the yes it will take more power, though that will come down as technology progresses. 5 years form now 100W GPU's will be much more powerful then current 100W GPU's

But if we talk in the context of fixed function hardware like image processors in TV's and blu-ray players then no there really wont be much of a difference in power consumption as thous chips have already had the time to be shrunken and refined compared to their 1080p counter parts. When 4k and 8k players come out on the market its highly unlikely that they will draw more power then their 1080p predecessors. It might even be the opposite and an first generation 8k player might need less power then the old first gen 1080p players. Who knows. In any case thous chips wont need much power anyway so its kinda a moot point.

We don't even have 2160p content yet. Are we going to jump straight to making movies at 4320p? I doubt it.

Well not strait away but there are a lot of people working to make 8k filming practical and its getting there. Honestly I think we are going to have moves shot in 8k far sooner then 8k TV's to watch them on. Like I said in my very first post. I think 8k will be stuck for a long time in niche markets like IMAX.

Really? Good. I like the sound of that.
