Two 450 watt cabs plus a subwoofer/subwoofers?

I woudn't use a powered mixer at all if I planned to run subwoofers.

But if you insist, you can always connect an amp just for the subs.

Or an active sub

alternatively, a mixer, power speakers and active sub

There is just not enough power in most powered mixers made to run two cabs AND a subwoofer. You may not notice the lack of power to the main cabs, since they will still get LOUD, but the quality of the subwoofer needs the full power capability of the subwoofer to properly drive it.

An active sub would be a good idea (though pricey), an extra amp just for the sub would be a good idea (though pricey).

I ran a Yamaha EMX88S powered mixer with a BBE sonic processor for the first year I did karaoke and it sounded great through the main cabs, though I never would have been able to divide the power up into a passive sub as well.

I finally broke down and recently invested in separate components (mixer, amp, etc.) in order to be able to pretty much infinately upgrade the system in the future. The mixing amp had its time in the sun, but when it came down to it and I was ready for some real serious sound, the components was the way to go!!

Just want to clarify:

I would guess that the BMB speakers gator is talking about is BMB CS-450 model.  They are unpowered speakers.  These speakers can handle up to 450Watts. That's why he asked about a mixer amplifier  to go along with it.  

I was thinking about adding a power/active subwoofer to it, too.  The power mixer may have preout outputs which I can connect them to the power subwoofer.

If it's for home use only he could probably get away with it a little more.  If it's for club use at all, i'd consider different speakers altogether.  BMB is nothing more than glorified (& overpriced) home bookshelf speakers.

Then go with Peavey....It depends on what you want to do with the system?  Is this for home, or is it for clubs?  Size clubs, how many people on average, outdoor shows?  
Peavey makes a couple decent mixer amps if that what you want to go with.  I prefer the Mackie 808S over any Peavey personally.  For speakers you could go with the Yamaha 115V Club Series.  But this may be too much for a home system.  You haven't stated what the system is for before you can get a better answer.

Then I stand with my recommendation.  Mackie 808S mixer amp & Yamaha 115V Club Series.  The mixer is expandable, has proper insert points for compressors, (3) 300 watt amps (into 8 ohms) built in - 2 for mains, 1 for monitors - this is clean power, not like the VocoPro "max" ratings.
The speakers will have enough bump that you won't NEED a sub in those size rooms over the BMB stuff that won't provide any kind of bass response & will be more prone to blowing out.  The 450 watt rating on the BMB is a peak handling rating.  These will only really handle about 100-125 watts continuous.

I'll confirm that the Yamaha Sv115 speakers are a great choice for most applications. They are great sounding very reliable speaker, heavy ..but not TOO heavy. And affordable.. Not cheap but a great choice.   The Peavey /Mackie / Yamaha / powered mixers are all great choices and come in a variety of power packages which you can match to your needs.  The cost of the Mackie is around $700-$800.  Definatley one of the "top of the line" units.   But if you don't need to buy top of the line ..I'll make a suggestion to look at the units from BEHRINGER.
I've been using a little light mixer PMH2000  (2 x 250w @4ohms) for a little over a year and LOVE it for small to medium size rooms.  The cost is $300.  (Can't beat it)
I'll admit the first one I brought hime had to be returned but since then the little unit works great.  I'm even thinking about buying their top of line unit which is rated at 2x 400watts @4ohms 10 channels - 99effects and the cost is only $349.

If you want to spend $700 on a powered mixer then go PEAVEY YAMAHA AND MACKIE --You won't be dissapointed  they are great units.  If your budget doesn't allow that then look at Behringer ... My opinion is you won't be dissapointed either .

Thats why I donate to this site.....the information is Priceless

I currently use the exact same Yamaha speakers and they are super clean with crisp highs and nice lows...consider putting a BBE 362 Sonic maximizer ($89) in the mix as they make the entire sound much much better!!

You might look at Yorkville for a power board and excellent lightweight speakers from their NX series.
