Question about Yamaha RX-V490 Receiver
I keep blowing speaker parts, 1 teeter, 2 woofers and an trying to solve the problem, playing cds through the LD section so we can watch dvd music.
Solution #1 is wrong. As you can see by the specs he provides, the Yamaha provides dynamic power reading for 8/6/4/2 ohm. I have Klipsch Kg4 (6ohm) speakers running on my Yamaha RX-V2095.
As far as amp power to speaker power goes. You are more likely to blow speakers using an underpowered amp and overpowered. If you go too loud using an underpowered amp it starts to clip the tops of the waveforms (distortion) and distortion causes the speaker's winding to heat and fail.
That being said. With 70W of power you shouldn't have any problems unless your speakers are "weak". If the blown speakers are isolated to a specific channel, you could have receiver-related failure, but I'm guessin it's your speakers.

Hi I have just read the specs on about your Yamaha system and you cant run 6 ohm speakers to your amp. You have to impedance match the speakers and the amp otherwise the speakers will "blow". So you need some 8 ohm speakers, the wattage of the speakers doesn't particularly matter as long as they are not too weak or too powerful becasue the amp will drive the speakers no matter what but if the speakers are of a low wattage then the amp could blow the speakers if it is turned up too loud. The specs of your amp are given in the link below.
