Default how much Wattage does your home theatre use?

just got a Kill-A-Watt and my home theatre uses 166 W while just watching TV w/ the stereo on.

I have plugged in the surge protector a /42LCD/Wii/PS3/Blu-Ray/5.1 receiver/UVERSE internet hub and cable box/3-way powered HDMI switch

with everything off I think it was like still 50-60w bleeding from stuff on "standby". NOt near as bad as I expected it to be with as hot as it gets in my media cabinet

I'm sure w/ blu ray going speakers at full blast and PS3 on downloading stuff it will really jack it up

2x500 watt (4ohm) amp for the subs
5x165 watt (8ohm) for the speakers
and I have no idea how much the sources (including computer) and projector use

I have no idea how many watts the amps use up watching tv.

Thirty watts for CD player plus receiver. There is almost no increase in wattage between turned on but idle and playing.

I've never measured it, but, I'm sure my reciever can't handle the 105watts x 6 like it claims ... probably closer to 300-400 watts total, but that's ok since my speakers are decently efficient. Dunno about the projector, Sub is rated for 250 watts rms (PL 200), probably is pretty accurate as it vibrates everything on the walls, in my entire house.

Although I don't have an HT setup, I do have a Behringer EP2500 for my sub... it's supposed to put out around 2100 watts RMS. LOL

I put a kill-a-watt on my system last year. I think it was about 650 with just the tv, reciever and cable box on. The sub was an a different outlet so that wasn't included.

Currently the (15") sub is in my car and with ~1200 watts is hits ~140db in the ~42hz range.
In home, I would like to make a box that would get at least 100db at 20hz, shouldn't be too hard.

Super easy really. my sub (see sig) could easily go to the 100+db range at 20hz. it models at ~113db. Right now itll go to about 95DB just playing a 20hz sine wave. Thats just a single channel on the ep4000 and the receiver set to -5DB for the sub channel. Going to 0 DB on the receiver would do it im sure I prefer it more in the 85db range so -7db on the receiver works for me

As for shaking of the house...meh only thing that really moves/shakes is an old cabinet we have (the doors rattle) and a picture frame likes to go sideways. And of course i have to watch what i put on to of the sub (its an end table design) as i dont really trust glasses of liquids. The little lamp on it hasnt fallen over yet though!

Did order a meter though, im rather curious to see what the system is drawing in standby and while playing a good scene with deep bass.

Sweet, my SSA Xcon 15" has just a bit more Xmax than your Tempest X, so I'm pretty happy to hear that you can crack 100db @ 20hz easily in room

I'd love to have a Maelstrom-X though *drool*

Well, I believe specs were back in 2001 were

130w center
120w 2x front
120w 4x surround
250w x3 sub (front 3 have subs built in)

So just speakers at full potential... 1600w + 55" led + ps3. Id wager I could hit 1800w on a good day.

55" XVT553SV used around 126 watts Daytime with backlight sensor on middle
Pioneer HTS-GS1 5.1 20 watts no heavy bass or background music ( during high bass/music scenes with the vol only on 30 it maxed at 111watts, and you can feel the vibrations from in seats.
Media Center PC ( see sig for specs ) 133 watts playing media player classic

I'm around 280 watts during the day and it's got to be less during night.

Power
P = IV

V = Voltage (volts)
I = Current (amps or amperes)
R = Resistance (ohm's)
P = Power (watts)

Power = Voltage x Amps

1800 watts = 15 Amps x 115 Volts

Provided you are on a 20 Amp circuit you can run that. The only thing is speaker rating is always at max capacity and 1600 watts is loud, really loud. By comparison our band used to run a full PA at bars at 1200 watts.

I would guess a lot, since I have a 50" Plasma TV, 700 Watt Yamaha 7.1 amp, cable box, and separate BluRay and DVD players. I'll have to plug it into the Kill-A-Watt to see where it tops out.

Edit: It looks like I use 400 Watts at a normal volume, and 500 watts when I have the volume cranked up.

Going by manufacturer data, 2x24W + 40W = 90W maximum power for my 2.1 system. Unless I move into a larger apartment or a one-family house, I couldn't even use any more than that.

Well, I can't measure from the wall but here are the RMS wattages:
Sub: 130watts
LR: 2x120w
C: 150w
Surrounds: 2x100w
HTPC: 200w
WHS: 125w

Maybe I should get a meter and find out for sure

I don't know about the projector, and other components
