[QUOTE="John_E_Janowitz, post: 6102866, member: 550657"] If you take a look at the impedance curve you can see the 2 breakups. The dust has a breakup at almost exactly 1KHz and is quite minor in magnitude. The cone on the 12" has a breakup about 2.4KHz which is more significant. Even if crossing at only 12dB as high as 100hz you'd be over 40dB down by the time you got to the first minor breakup from the dustcap and over 50dB down by the cone breakup. For any subwoofer application the breakup is not even remotely an issue. If you plan to use the drivers up to 500hz or so in a 3way home speaker then you'd need to take a little more care. You'd want to have a 24dB slope to keep these breakups suppressed. These drivers actually will reproduce the lower vocal region as well or better than most good midrange drivers. I doubt anyone on this forum needs to worry about it though. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] John [/QUOTE]
