The 808M is actually 2 300 watts amps at 8 ohms. The 600 watts is a 2 ohm rating. But it is still a close match for the CM212V which should be getting 400 watts.
The PMP2000 is only rated 165 watts into 8 ohms - again the 300 watts is a 2 ohm rating, most speakers are 8 ohms, but for a home use should be ok for most purposes.
The Yamaha BR12M would be an ok choice.
The Peavey PR12 isn't my favorite, but is cheap - although power hungry.
Even cheaper yet & even a less fav of mine is
http://www.musiciansfriend.com/product/ ... sku=600697 but this speaker would best match the power rating of the PMP amp pretty close.
You wouldn't want to go with an active speaker running a powered mixer (I mean you actually could but you would be ending up spending money on a speaker with an amp when your mixer IS an amp).

I was stateing the mackie info at the same rateing that dreamaholic stated the pmp2000 at so he could compare apples to apples but thanks for the watts to ohms break down...The mackie is 1200 watts bridged and the pmp2000 is 800 bridged if that is any further help.
Actually sorry to say the Mackie isn't bridgeable. The 1200 watt rating is a combined figure of 2 600 watt into 2 ohms. Meaning if you were using 4 8 ohm speakers per channel, THEN you would yield the 600 watts per. Since most speakers are 8 ohms, the 8 ohm power rating of the Mackie is 300 watts per channel.
Bridging is actually combining both channels together to yield 1 channel only using both channels combined power.
The PMP is actually only 500 watts bridged @ 8 ohms btw. 800 watts is a peak figure, not a continuous number. Never go by peak ratings - these are just tactics by companies to make one think they are actually getting more. Same with using the 2 ohm wattage rating. 1200 watts sure does sound alot better than 600 watts?
But again, it doesn't really matter was just trying to clear up some common misconceptions in the way people read power ratings in the way manus market them.

Maybe I didn't understand correctly but dreamaholic is looking for monitors, I took that as he wanted floor monitors but maybe I was wrong.The br12m would probably make be an ok choice,the differences between the br and the cm is finish on the cabinet the grill and 50 less program watts and 100 less peak.The pr12 I've have'nt seen those in a monitor cabnet and the s1520 didn't look like a monitor cabnet either.But like I said I could be wrong,maybe dreamaholic is looking for frontal cabs and not monitor cabs.
I don't know if he was looking for monitor cabs specifically as wedge types, I believe he was looking for a main speaker in general as he originally stated 12-15" cabinets.
Some monitor speakers are good enough to be used as mains.
I was more trying to match his power amp (165 watts per channel into 8 ohms) to a speaker. Underpowering a speaker can has adverse effects - ie blowing them. Mainly why I waas going for the lower rated speakers. The PR12 actually require 400 watts (why I said power hungry). The BR should have about 300 watts. The Behringers again I said would be the best match overall to the PMP (although definitely not my favorite brand). These require 180 watts at 8 ohms, the mixer/amp pushes 165 watts @ 8 ohms. Very close match!

The cm12v(not cm212v) are a 350 watt program and 700 watt peak,please explain why 400 watts would be better than the 300 watts their receiveing.
Always willing to learn more.
Sorry I typo'd, added an extra 2 by mistake.
I said the 300 watts that the Mackie pushes is close enough to the CM speaker. 400 watts would be ideal although in this case not AS big of a deal as if the PMP amp were pushing them.
It's more a matter of headroom. Figure your speaker is going to run at it's best with the rated program rating. The amp only pushes 300 watts of clean power (supposedly - different frequencies will play factors here but for all intent purposes say it's true). So you are running your show, pumping along - volume is good. You need to bump your volume up because more people came in, got to cover crowd noise & body absorsion. You didn't realize that the amp was already pushing it's maximum 'clean' power, sure the amp will push louder than 300 watts - but now you are starting to drive into clipping, you may not even realize it at first, however the speakers eventually do. They may start to sound a little tinny in the high end, bass response may seem to start lacking a bit, midrange tends to start dominating a tad. Over time, the voice coils start getting hot & eventually will fail. Again, the extra hundred watts wouldn't a huge factor in this case, but may be the difference between a tinny sound that can get ear fatiguing & a nice full sound because you are still listening to clean power.
Ever go into a karaoke bar where it is loud but not real pleasing to listen to because it's usually real ear piercing? This is generally caused by low powered amps turned up too high. I'm sure you've been to other clubs where the sound is loud, but you can hear everything, it's not real ear fatiguing (hurting), sounds clean - this is usually because everything is properly powered, pushing clean power. More power is always a good thing, doesn't mean you have to turn it up, but it WILL mean fuller/cleaner sound at regular listening levels.
