Does anybody know how the 3 speakers of the T-310UL are wired together, so that the overall impedance results in 5,3 Ohm ? I see two alternatives: a) All speakers have 8 Ohm, 2 speakers are wired in series (results in 16 Ohm), the 3rd one is wired in parallel to them. b) All speakers have 16 Ohm and are wired in parallel. If a) is true, then the single paralleled speaker gets 500 W power from a 750 W amp, the two remaining speakers get only 250 W. That doesn't make sense... But if it's true, then it would be a simple reason for the 310UL hazards reported here at TB... can't believe it really... On the other hand I can't believe that Epifani uses 16 Ohm speakers (b)... Who can help ?
