Bi-Amp & Matching Help Please!!

rodepode

Where do I begin? Please excuse my ignorance with speakers. And of couse
I am new on here.

So, I own an Onkyo TX SR605 (7.1/ 90w a/Channel)
And for the front L & R I am placing two Polk Audio Monitor 50s
for the Center a Polk Audio CSi 30, and for the surround two Polk Audio
Monitor 30s and finally for the sub a Polk Audio DSWMicroPRO 1000.
(12 Gauge Monoprice.com speaker cable)

So my questions are, since the R50 are rated at 150watts, does that mean that when I will be biamping them (which my receiver can do by taking the two rear channels for the "bi" aming) does the tweeter take 75 watts and the woofer take the other 75 watts? And Does that mean trouble since I would be sending 90 watts for the tweeter and 90 watts for the woofer since that is what my receiver pushes per channel? And then, am I ridiculous for having the Polk Audio CSi 30 as my center since it is rated up to 180 watts and I my receiver only sends up to 90 watts for the center? Also, I am supposing that the two rear Polk Audio Monitor 30s are fine since they can run 100 watts and my receicer can send them 90 watts each. And of couse, finally, the DSWMicro PRO 1000 was a great choice, no questions there and no problems. So can someone please answer me? I am clueless as to if my system is now severely "unbalanced" because maybe I didn't do enough research/enough money before I Newegged all of this. Thank you!!!

You all are the best and passion for Audio is the best feeling in the world!

Not knowing your AVR and speakers very well I would have to say you most likely just fine with your speakers to AVR choices. As long as you don't like concert level volumes.

You will more than likely be underpowering your speakers. This is worse than overdriving your speakers with too much power. You might think this is odd but at high volume levels your AVR might not be able to put out the wattage it claims and start to clip which sends bad power to your speakers and will do more harm than having too much power sent to them.

IMO it is never bad to have too much power. You just have to be smart and not crank it up beyond the speakers ability. You can do more harm underpowering than overpowering.

I know that seems backwards but it is true. Hope that helps.

I wouldn't bother bi-amping them that way. Since you are still relying on the built in crossover of the speaker, your benefits will be minimal, at best. More than likely you will see absolutely no improvement. The tweeter will not be using the same amount of power as the woofer, woofers generally use more power, since bass is more kinetic energy.

If you truly want to bi-amp, you have to use an outboard crossover, two separate amps, and remove the crossover in the speakers.
