Dump yer z560s and Klipsch for these babies!!!

[KatLei]

580W 2.1 speakers for $18.99!!!

HOT HOT HOT!!!!!

Hahahaha... These can't possibly be anywhere close to 580W

My z560s would probably blow these outta oblivion even at 1/3 the volume dial...

 

[akahai]

I think the high end tsunami speakers were actually pretty good.......

 

[Mixxen]

PMPO/MAX = CRAP
RMS = USEFUL

Basically if a brand advertises Max/PMPO power, then they are crap. Respectful companies advertise RMS power.

 

[KatLei]

It's just advertisement strategy. Might fool anyone who isn't an audiophille...

580watt PMPO << 400watt RMS

get your power ratings straight

my 30 watt speakers rates 500watt PMPO

 

[XFreebie]

hmmm

 

[UF Jspec]

I'll stick with my ValueAmerica Yamaha YST-MS50's!

 

[scoreadeal]

I'll out do you all with my cluster of PC speakers! (recently upgraded from 5.1 PC Speakers)

 

[blahblah99]

pmpo = possible maximum power output, the only way they can get that 500w out of those speakers is if they blow up the volume for a microsecond and count that as 500W.

You guys are completely overexaggerating the difference between RMS and PEAK power ratings. If you want to do the math, to get RMS from a Peak reading, simply divide it by the square root of 2. To get a Peak rating from an RMS rating, simply multiply it by the square root of two. So this 580W speaker set that you geniuses are claiming to be weaker than your 30W system is actually 410W RMS. So, illuminatus, get YOUR power readings straight. 580 peak is not much much less (infinitesimal compared to) 400 RMS, it's actually greater than 400 RMS. Get your crap straight before you claim knowledge of a subject.

Good deal for some.

Not to rude, but you need to do some research yourself: Look here or read below:





What is RMS?
RMS stands for Root Means Square. It is the power that really tells you how powerful an audio equipment is. A typical specification might read 100 watts RMS into 8 ohms i.e. the electrical unit of resistance from 20 Hz to 20 kHz at .01% THD i.e. Total Harmonic Distortion that is the percentage of distortion present in an audio output signal. The lower the percentage the cleaner the amplifiers output. What that means basically, is that an amplifier can deliver 100 watts into an 8 ohms speaker from 20 Hz to 20 kHz. This frequency range is basically the entire audio range that an individual can hear. The RMS is usually categorized as per channel i.e. either left side of signal flow or right side of signal.

What is PMPO?
PMPO stands for Peak Measure Power Output. This is a test of the audio equipment's ability to go beyond the RMS for a very short period. We are not talking minutes or even seconds here. We are talking milliseconds or thousandths of a second. Here is how it is done. An audio equipment is fed with a 1 kHz signal for 20 milliseconds, the volume control is turned up until it reaches a clipping point. At this point, the piece of gear has reached its instantaneous peak or dynamic power output. This peak is what is measured in PMPO. Please note that PMPO is not a correct term used to rate audio equipment and it is very misleading for the average consumer. Again, it is measured in terms of Watts. An important thing to know is that approximately, 8 watts of PMPO power is equal to 1 watt of RMS power. Thus, to find the power output of any audio equipment, use this thumb rule.

 

[kinkyboy702]

Oh yah, a rough estimate for these speakers would be 72.5 watts RMS.

And even that is far too high. I've seen speakers with PMPO ratings that were 30 times the RMS rating.

Well then Mr Physics Genius, why don't you tell me why my old midiland 350 watt PMPO system (247 watts RMS, according to you) sound like cr*p compared to Altec ATP3, which is only around 30 watts RMS? I'll tell you why. The midilands (MLi 350) were 18 watts RMS (2x 4 watt sats, 10 watt sub.) 18^2 happens to be pretty close to 350 (324 to be exact,) which means the PMPO rating is actually the square of the RMS rating. That would make the Altecs 900 watts PMPO and the z560 "only" 160,000 watts PMPO. In other words, PMPO rating doesn't mean much. BTW, those particular speakers are going to be around 24 watts RMS. Not bad for $19...

 

[dp004i]

Actually, they are much worse than I thought. 11 watts RMS - 3+3w sats, 5w sub. Also, they have a tiny 3" speaker in the subwoofer. I wouldn't touch those with a 10 foot pole. Don't believe me? Take a look at this page: http://www.tsunami.com.tw/h-shadow.htm

 

[dp004i]

All right, I guess I was wrong about the way to calculate the PMPO rating. Here's what you need to do to find it, the way all those crappy speaker companies do: take out a piece of paper and write down a huge number that would make a newbie think the speakers are loud enough to rock the pictures off the walls.

You'll have to pry my cold dead fingers away from my Z560's.

sighhh.......i still use headphones...........and they just broke.......but i want more headphones! thinking of getting the wireless headphones from that infiniti deal......but then that means no m100.....who said life was easy?

i think i have enough people defending me already. thank you.

btw, you're confusing max power with PMPO. yes, max power (in an electrical engineering point of view) is RMS x sqrt(2), but PMPO is NOT max power

plus, i read my 500watt pmpo right off the spec sheet of my 30 watt RMS speakers, what's the point of you flaming me?

I smell something burning around here.. Don't think I'll touch this post with a kevlar flame retardant suit on..

Holy crap! I'm all over this deal!!

 

[Mockmaw]

Am I the only here that thinks that wattage isn't everything? Buying something for the raw numerical values associated with it isn't a great method of using your money.. that's like buying a video card because it has the highest theoretical output. That's why I think that speakers should be bought (or at least tested) at a place where you can actually hear them. Who gives a damn if they're 8 gazillion watts if they still sound like a fart in a tin can.

My cheesy yamaha 2.1 piece system sounds better than any other speaker regime on the market right now (to my ear).. I don't know what the wattage is, and I don't really care.

 

[Aharami]

yeah. nice offer...but i think i'll stick to my Z-560. thank you. If you dont have these speakers...GET EM!! omg they sound so good!
