IMO, the vibrations induced on the speaker cones are not great enought that you could tell a LARGE difference in sound quality...especially when other sounds are thrown in the mix( tires, engine, wind, etc.).
like has been said, you can get tight bass from a good set of components in an enclosure that has enough volume, like the above sound bar. however, by making these 6" or whatever speakers produce bass, the midrange will suffer.
IMO, a good set of components with the lower freq. filtered out with a cut-off of 100 to 175 hz is the way to go. dont cut off too high so you still get some punch, but not too low so that the midrange doesnt degrade and the speaker doesnt move too much.
then send the lower freq to a sub. if youre concerned about size, an 8" bazooka is not too big and gives good bass to fill in the lower freq. you wont be setting off alarms here and they come in powered and non-powered versions so you dont have to get an external amp.
I run an alpine 9833 head unit. alpine amp 75WRMS by 4channels, a set of FOCAL 5.25 polykevlar components in the front, a set of 5.25 Boston acoustics in the rear, and a 10" infinity kappa in a custom bandpass enclosure, and a 1 farad cap to keep the amp really happy.
The head unit runs the rear bostons with 27.5W RMS with the freq cut off at 200hz by control of the head unit. the front focals are on 2 of the channels of the amp @ 75W RMS cut off at 125Hz by control of the head unit, and the sub is powered by the other two amp channels bridged with a cut-off of 150Hz by control of the head unit. sounds clean, not too much bass and the mids are amazing.
There are two types of crossovers( filters) passive and active. Passive crossovers are attached on the high level imput to each speaker and filter out the freq. these consume power going to the speakers and are usually a network of resistors and capacitors and/or inductors. this type can be found in home audio speaker cabinets and are found in the little box that came with the FOCAL components(separate the tweeter freq from the mid freq). Active crossovers are on the low-level side, or in the amp/preamp/headunit and dont use any of the power going to the speakers to function. Active type are nice because you can often control the cutoff freq by turning a dial.
For example, in my alpine head unit, you have control of each channels filtering within the digital menu. you can set each channel to high-pass(for midrange speakers), or to low-pass(for subwoofer). you can set the freq of each cut-off, and the sharpness of each cut-off(2,4,6,12,24 DB/octave). additionally, i could do some of these changes at the external amp, but i choose to have them at my finger tips.
Speakers that are designed for low freq, bass, are usually not good at midrange sound because their cones are too stiff and their not compliant enough. speakers that are "full range" are a compromise and will not last as long with the low freq , large displacement, motions and the sound will become muddy.
