Gregg Hagge: 1000 rms watts may be expressed as 12000 "Music", "peak to peak", "dynamic", or other ill defined "watts", but it doesn't matter. Unless you have a huge home and very inefficient speakers you are wasting your money aiming for that type of power.See the 1st link for a quick overview of why a 100 watts/channel system is all you likely need. In brief, loudness is not a linear function with power. You need to double the power (watts) to increase the loudness 3dB (barely noticeable), so even a low power amp (2-3 watts) will drive efficient speakers to a respectable level. You need more power than that for high dynamic range material (e.g. piano) played at realistic volume, or for larger rooms, or for inefficient speakers ... but as mentioned, few people NEED more than 100 rms watts/ channel.I suggest you focus on other aspects of home theater than power. There is a lot more to selecting a home theater system than power rating. In fact power is one of the least i! mportant issues....Show more
Chastity Doderer: 12000 watts is a lot of power and it takes a lot to accomplish this. My HT is less than 5000 watts and the combined weight of the amplifiers is over 400 lbs. You would need a fork lift to move a 12000 watt amplifier. So if the thing you are looking at is smaller than a commercial washing machine and weighs less than about 800 lbs, it's not 12000 watts. And just so you know, you're going to be talking about spending over $10,000 US$ for this kind of power.There might be a few large I-Max theaters that have up to 12000 watts at their disposal but they would never run it to full capacity. For a home theatre you don't need all that much power. The typical home theatre is only a few hundred watts at best. As for what the "1000 watt RMS" means on a typical HTiB, it is an arbitrary number stamped on it by the manufacturer in an effort to impress. No so called "1000 watt" HTiB can get anywhere close to 1000 watts no matte! r what they claim. Usually this is based on a summation of po! wers that can not be summed. For example, a receiver may be capable of 150 watts/ch and it may have 7 channels. The manufacturer will just multiply 7 x 150 and get 1050 watts. Problem is that the power supply can not support all 7 channels at full power at the same time so it is misleading to just add the 7 channels together like this. In reality, it may only be capable of 300 ~ 400 watts or less. Possibly a lot less.Stop worrying so much about how much power you have and look more toward sound quality and just make sure it is capable of playing at an acceptable level for your needs. How much power is required to accomplish this isn't important. The sensitivity of the loudspeakers also plays an important role. A speaker with 3 dB higher sensitivity will require half the power to achieve the same playback level. Power isn't everything!mk...Show more
Maritza Ebanks: I have no idea why you are so obsessed with watts, but a watt is a measure of electricity, and b! y itself, means very little. Which is way so many companies take advantage of this and advertise their wattages, often at highly inflated and ridiculous figures. 1000 Watts RMS means Root Mean Square. This is the standard way to rate wattage. I don't know what the formula is because I have never had a need to use it. A manufacturer may have an 800 watt system that they advertise at 12000 watts, but this may mean nothing more than they measured 12000 watts running through their unit before it melted or exploded. This is a popular game with car audio equipment, but home theater appeals to a more discriminating crowd, so most manufacturers (in the U.S. at least) will only publish their RMS ratings because they don't want their customers to lose faith in them. If you want good sound, you should tell the shopkeeper how much you want to spend, and let him show you what he has. But if you want a good sounding, real 12,000 watt system, you better not even have a budget. You! 'd probably have to get equipment designed for movie theaters....Show m! ore
