Or am I missing something with my train of thought?
My towers, for example, have dual 10" woofers. They are still handling 80hz to 10khz. Lot to deal with. I think the horns take over around 1250hz, so those dual 10's are handling 80-1250 roughly. Plus, if set to 60hz, there is a noticeable gap in performance. I think everyone's setup is different so it isn't a blanket statement, but I have dual FV15HP's, there is no reason not to let them handle up to 80hz, and then let the towers and center handle 80hz and up.
Also, some folks running smaller fronts and centers have them wrongly crossed at 80, when they could possibly need to be crossed around 90 or 100. Only way to know is try it out, and I have proven mine sound better at 80hz. Finally, the larger tower is not exactly so you can cross it lower, it is so that it is more powerful in the range you set it to. My large towers set 80hz destroy anything I have had previously, that were set to 80hz.
There is also the matter of power, the lower you set fronts, the more power you need. Good ID subs are powered up properly for the task at hand. I generally watch blu-ray movies around 0.0 to -2.0db volume, so power is key.
