Thanks erik, the speakers are Sopra No.2 and they each have 2 woofers. For sake of description, the left channel full speaker works great, the right channel has the problem. The right channel upper woofer, does produce lower sound and volume but no body, when compared to the same woofer in the left channel speaker. Also the upper woofer Right channel does have some movement, while the lower woofer Right channel operates fine. Would this rule out any crossover problems?
Thanks,
