I believe John is saying that you can not add the 2 seperate powers supplies together to achieve the 260 watts for each speaker. He is saying the woofers are still only getting 130W and the mids/tweets are still only getting 130watts, you can not add those 2 together as if they had 260 watts of power to draw from as they don't, there is still only 130 watts of power to each binding post, which is not the same as 260W. The woofers will be drawing from 130W and the mid/tweets will be drawing from 130W, 2 seperate channels on one speaker.
What has happened in this formula is the load on each channel has dropped and you should be able to push each one a little harder before clipping.
