So I have a pair of Polk RTI 10s hooked up to a pioneer VSX 823k receiver. Does 80watts rms per channel and max output is 140 watts. I was playing some pretty bass heavy music yesterday and the bass wasn't really there unless I turned my polk sub on. So, I looked at the woofers on the Polks and while playing some bass heavy songs, the woofers didn't seem to move much, unlike the midrange above it which was whacking back and forth. Any idea if this is a problem or just needs some serious juice to get them going. - Thanks
Wait, you had the speakers crossed at 100hz and you had the sub off? You wouldn't hear much bass because all of that information is going to the sub, which is off. What happens when you play your RTi 10's full range on their own? Also 100hz is a really high crossover point for them. 80hz is probably as high as you should go

Tell your avr it has no sub connected to it and your speakers will play all the bass they are capable of.
Lower your crossover and your speakers will play more of the bass frequencies in the source material.
Set your crossover and enable your avrs double bass feature, which will allow your speakers to play the full range signal and your sub to play bass frequencies below your set crossover. This can have negative cancellation effects and is not usually recommended.
Simply cutting the power to your sub without telling the avr that it is not in use will eliminate bass below your crossover setting.
