There seems to be a related effect at the other extreme also which has been noted with RELs Sub design. Even though we do not actually hear the effect there are things happening below both thresholds of 20-20K.
Here is a dialog taken with the REL Designer.Sorry this is getting away from the question,but both extremes should be explored I thought. Having true intergration must be addressed using either exterme I imagine.If not I would think there would be unwanted overhang which would muddle up te effect or benefit of using a either a Super Tweeter or Sub-Sub Woofer!

This is to answer to a question I think sbg had about the article I had alluded to in a thread about Bass Reproduction with subs. The initial question I had was why most speakers that were on the market could not have the kind of extension I would want .Another words Full Range for an affordable price. There are a few exceptions like speakers from VMPS. This is the article I had mentioned.It was from ABS not S-phile.
If it was not sbg then excuse the reference to him.

Putting aside enclosure and room-mode issues, with a large multi-way you are confronted with the problem of trying to make drivers of unequal size ,mass and material composition sound like one unit. Though crossovers are theoretically designed to do just that, anyone who has ever yoked subs to an electrostat or good mini-monitor can tell you that whats true in theory is not true in fact. Just listen critically to the midrange of any such speaker before and after youve added subs.I dont care what sub it is or what slope or filter you apply; youre going to losse something in the way of soundstaging, transparency, dynamic speed, dynamic speed and nuance, and inner detailin short, youll lose a significant amount of what you bought the the speaker for.(Of course you gain something , too,in the way of body ,midbass authority, instramental weight, and low bass extension but lets not pretend that these things dont come at a cost that some of us are unwilling to pay)
