RMS vs PMPO

[wrack]

I was just wondering that if someone knows what is the conversion ratio to get PMPO from RMS of speakers.

I am really confused as 1 figure I found was,

45 Watt RMS is 1000 Watt PMPO

Does anyone else knows about this...???

[parksie]

There isn't really a conversion factor. RMS is the power that it can continually provide, in a stable way. PMPO is exactly what it says, Peak. It's when you just go *THWAP* on it and get a massive burst of current.

[wrack]

But by comparing my old ones and new one I can clearly hear a voice which is basically double than the old one.

In this case it really comes to the 45 to 1000 factor. Anyway I was just curious so I asked.

Thanks for reply.

Does anyone else have better idea about RMS over PMPO...???

seems like an awlful high peak. I've always been told that peak is roughly twice that of RMS.

is it 100w or 1000w PMPO? according to the logic above, 100 would be closer.

[wrack]

Well practically when I hear both speakers out, it looks 1000 to me.

[vfluckey]

bonus for you then

the only thing I know about speakers is what i've heard (no pun!)

you might want to compare the resistance (ohms) of the old and new speakers to see if they're the same.

Well RMS is the "real" power that the speakers and amplifier can handle.
A 45 Watt Speaker-set (with amplifier) gives 45 Watt to EACH speaker, continues (30+ sec) with a very acceptable distortion (5% or so) .
PMPO is the power that ALL speakers togheter for a very short (~2-3 sec) periode of time can handle no matter how great the distortion is ( say 50%).
And don't believe to much of the PMPO power. A regular amplifier for your home, at a normal volume (not back-ground, and not disco like) is about 5-7 Watt, that's all.

[wrack]

That still doesn't cover what I am looking for. And I can't find Ohm for old speakers so can't compare it.

Anyway new ones have 41 Watt RMS alltogether. Is that good or OK or bad...???

Cheers.

41 watts rms is plenty for most house systems especially if you are running it off your PC. what really makes the difference between good speakers and bad speakers is the Box the speaker is in. (eg. bose lifesytle are the best systems in the world and the speaker cones are tiny. this is beascase they have designed the box very well and don't just shove a massive cone in a cube and drill a hole in it.)

Sorry i was rambling.

anyway yours sound good enough. (and anyways every one's hearing is different anyway, what sounds perfect to you may sound not so perfect to others.)

(i do PA systems as a part time job and have just finished building a 3000watt rms valve amp. it rocks )

[parksie]

I wouldn't say Bose were the best in the world...I'd put my C420 up against one any day for quality

[Bloit]

Matter of opinion. everyones hearing is different. C420's are good.

I still go for with BOSE on this.

[parksie]

They make very good all-in-one systems, but you can't beat a set of hand-picked hifi separates

[wrack]

Check YOKOHAMA. They kicks a** too.

If needed for PC then check Creative Megaworks THX speakers.

[wrack]

I guess no one here is a sound expert. I need to go to JB Hi-Fi store and need to ask someone there.

Don't they make tyres???

That's a different but as far as I know there is one company in Japan which also makes speakers which is named yokohama.

Could be wrong though since can't find it on net but I did show the speakers once.

Cheers.

What was I thinking...so sorry.

It's http://www.nakamichiusa.com/

Not yokohama.
