I have a sansui quad receiver that I want to try out with 2 B&W CDM 7SE for the front and 2 CDM 1 SE for the rear. The sansui is rated at 25 watts per channel into 4 speakers and these B&W's are rated at 30 watts minimum. can this set up cause damage to the speakers and how could I get more power to the sansui and still use the quad features it has? Is this possible? thanks for any feed-back....
