1000 watts? REALLY????

[Forrestandjen07]

So my girlfriend bought a new home theater in a box and its 1000 watts, how are these things giving out 1000watts ?????


when most Decent/high end traditional recivers are only like up to 200 watts

why use traditional Home theater equipment thats more expensive, when you could be using those?

Could be a lot of things, but the principal reason, I'm guessing, is that the HTIB is 1000W total (all channels combined). AVR's are typically quoted in watts per channel: 7 channels X 200W = 1400W.

Also, there are "good" methods of measuring power (watts) and less-good methods. We don't know which method the HTIB manufacturer used.

yea i know untill HTIB starts providing DDHD and DTSHD 7.1 im still going to use the traditional setup

i was just currious how these systems can be so powerfull for so cheap

Some say 'Peak' and some have 'RMS'

There is a difference in 1000 watts Peak and 1000 watts RMS

Class D amplifiers are intrinsically cheap and it was probably assembled in a country with extraordinarily cheap labor.

First off, do not believe everything you read, in any real world situation you won't get 1000 watts from a htib. Also,remember that all watts are not created equal, quality is far more important than quantity, 50 quality watts will be much better than 120 crappy watts.

Could be they lied?
Could be the front panel is lit by 10 100 watt light bulbs?
Most likely the number represent the peak that all channels together could output in a single brief spike of uselss power.

[STARSCREAM]

That is the total number combined for all channels together.

Clipped all to hell and just before it melts.

No HT in a box or receiver can output continuously even the stated 100 watts or 150 watts per channel. It is all marketing hype and B.S.

Cinepro is one of the companies that makes extremely powerful separate amplifiers. Their top-of-line amplifier is Cinepro 4K6 MK4 SE-Gold. It has 6 channels and weighs 86 lbs. These are the specs:

Multi-Channel Mode
475 Watts per Channel, 8 Ohms
650 Watts per Channel, 6 Ohms
800 Watts per Channel, 4 Ohms
1200 Watts per Channel, 2 Ohms

Mono Mode
1200 Watts, 8 Ohms
1400 Watts, 4 OHMs

Ive seen a few HTIB saying 1000 watts. like Panasonic, Sony, JVC, etc. You probably can count around 150 for the sub. Matter of fact, you never mentioned what brand or anything else.

I stopped reading right there. . . You let your girlfriend purchase A/V equipment without your approval? Is this a short term relationship? The only way this should happen is if you are also a girl. Seriously, it's time to lay down some ground rules.

[hoogoosedmoose41]

I think ill take the 200 x 5 rating on my rotel amp over a HTIB rated at 1000 watts any day.

True.

[maverik1979]

this is an extract from a sony instruction manual quoting power outputs
as you can see it is measured in RMS, as all good watts should be

but it states running at 10% distortion, which is so bad you wouldnt be able to hear much, and its only measured at 1khz, which is around the normal frequency of speech, really good av equipment specs are rated at less than 0.01% THD (total harmonic distortion) and from 20hz-20khz as a minimum (often much more) for example my amplifier is rated at 130wrms/channel @ 8 ohms with 0.00028% THD (25 year old sansui, built like a tank),
also the sony is quoted @3 ohms, and as a rule of thumb if you half the impedance you double the power output (if your power supply can handle it) so again as an example, my amplifier will kick out 260w @ 4ohms/channel , and 520w@ 2 ohms (briefly)

last but by no means least, there is no way in hell, that the crappy speakers they supply could handle that power, if by some amazingly magical feat the amplifier could output anything like its supposed power (which it cant)


hope this clarifies for you

Seriously, look at the utility power it requires, in Watts, and multiply by .75. Assuming between the transformer (in)efficiency and the power cost for the rest of the system is only 25%, the remaining is what is left to possibly power the speakers. Watts is Watts. I'd guess it can't do continuous, peak, or RMS at 1KW. Given efficiencies from AC to DC that means it's drawing better than 10A from the wall to do 1K. Yikes! I hope her hair drier isn't or iron isn't on the same circuit!

Um, She is not an aduiophile she just wanted some large sound other than the crappy tv speakers at a decent price, she also dosent have Hundreds of dollars to spend on a "professional" setup

and it sounds pretty decent

i was just trying to figure out where the "1000watts" came from

[HOME THEATRE ADDICT!]

So far Ive never seen a HTIB that would satisfy me, and I dont have the best of everything now!

[Forrestandjen07]

Our next step is getting her an HDtv, which i am picking out, im really picky about these

and the time of buying mine i had to go super cheap, and it looks kind of ugly ( the screen housing) so i hope to avoid this with hers

eventually il get her a real reciver but for now the HTIB well do. i was just currious on how such a tiney and small piece of equipment,could do 1000 watts

thanks for your answers
