ABC is the rip

You shouldn't have to have your subs playing up to 180Hz to get good midbass response. There are plenty of reasons to never have your dedicated sub bass drivers playing that high not the least of which is with most subs located behind the listener at higher frequencies the subs location becomes much easier to locate with your ears. A decent dedicated midbass properly installed should give plenty of impact allowing your dedicated sub bass drivers to reproduce the sub bass it was designed to produce.
If your fancy $400 a pair midbass speakers can't get the job done they were either the wrong driver for your application or their install was poorly done.

Nothing wrong with my drivers or Install and deffiantly no localization issues...the sound of woomf woomf from my subs LP @ 60HZ is not my idea of balanced sound. A good sub LP @ 170HZ will always out-perform any 6"woofer in the mid-bass region, no 6" woofer has the same dynamic impact as a sub LP higher...and no 6" door woofer is ever capable of producing punchy upper midbass dynamics that are felt in your chest cavity. My subs hit hard and blend in very smoothly with my fronts.

Righty then, either you have not really experienced car audio as you claim or their is a inherent design flaw with your system. But hey, if your system works for you that is all that matters.

my midbass hit down to 80 hz... theyll go down around 65 if i tune for it, but i dont have the power to do that.
it is loud, deep, and authoratative, playing an 80hz test tone, they sound like small subs.
i also tend to wonder about your meaning of no localization, i dont know exactly how youve got your system set up, but on every sub ive ever heard, anything over 100-120hz will allow you to pinpoint its location.
I would like to know what kind of box you have that allows you to defeat this phenominon, because ive got a project that a setup like that would be perfectly suited for.
as for no 6" woofer being able to perform like a sub, why not?
what is the difference between a 6" or 8" sub, and a 12" besides size?
do they not both have cones, spiders, coils, poles?
a speaker is a speaker is a driver is a woofer, theyre just optimized for different frequency ranges.
get enough cone area from 3" speakers and they will produce just as much bass as a 12" sub.

I can't beleive i just read that a good sub LP at 170hz.I've never had a sub LP's higher than 70HZ myself. Anything over 80Hz is considered mid bass( hence name midwoofer) anything below is considered sub bass ( hence name subwoofer).Just think abouit it, you're using a SUB-woofer for MId-bass, get it.
