When you use passive bi amping, like you are, each section of the speaker is capable of receiving 60 watts max. The lower half and upper half cannot be added together as neither section is receiving 120 watts, the are still only getting they same 60 watts.
So assuming the mid+high is drawing the max 60W from one channel, and the woofer is also drawing the max 60W from the other channel, isn't there 120W of total music power coming out of the floorstander? 60W of mid+high energy from its dedicated channel, and another 60W of bass energy from the other dedicated channel.
If the straps were left in place and the floorstander is driven with only one channel of 60W, assuming a 50/50 split then the woofer gets 30w and the mid+high gets 30w.
In any case, what is the benefit of bi-amping? The ability to pla y twice as loud (120w total music power) vs 60W, or playing with less distortion at the same level as each channel is only at half power.
