No test needed. If "underpowering" hurt a speaker, they'd be no reason to have a volume control, it'd be 100% full volume, all the time //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifThere was a test on a sub awhile back.
There's more to cooling than just the diameter of the voice coil.....3 inch coil on both................................ is it wound differently?

It is when you consider the time it takes to machine each driver to spec in house. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifthe cooling feature is sub par at best. not necessarily a reason to raise the price 40 bucks on the speaker.
