[QUOTE="huricaine, post: 7636241, member: 622532"] Lets see.. Does Low xmax = low Qts? No. Didn't mean it that way. Does using a shorter coil winding(less xmax) given all else is the same = more motor force, and thus a lower Qts? Yup! Next... Motor force isn't everyhing because some apps don't require alot? Yea, CAN be true. And then you go on to say that a sealed box sub will have an F3 of like 50-60hz lol...mhmm...Let's look at an example of a sealed box sub: RE XXX. It is a LARGE motor. The compromise here is that it requires alot of backbone to achieve a high enough efficiency with it's LARGE top plate and little coil(even though it's not necesasrily "efficient"). This sub still has a Q that is up there. In this case the sub does not have an F3 of 60 hz sir! About me saying that a looser suspension raises fs, it happens, common mistake, i accidentally reversed that as i replied quickly. Adding mass really does not take a whole lot to alter the Q and Fs.
