4 way speaker will have 4 voice coils - bass, mid range, high range and a tweeter. 2 way will have 2 coils.
Coaxil speakers share one coil, magnet and drive piston whereas a 2-way speaker has 2 individual coils for the speaker and tweeter which make for generally better quality.
A one way speaker delivers all the frequencies of sound in one, a 2 way speaker divides the frequencies of the sound.
5 way is the amount of speakers that the system has connected to the receiver unit.
The original speakers suck. I replaced them with some 6 x 8 Alpine 2-way speakers. Big difference even with stock stereo.
The difference is the number of actual speakers in the unit and how the sound is broken up. If I'm correct a 2 way speaker does Mid/Lows from the main cone and Hi/mids from the smaller cone. A 3way speaker has a tweeter (for hi's) a cone just for mids and a sub-woofer for the lows. This allows you to get a clearer crisper sound at higher volumes with less risk of distortion.
A 2-way speaker's crossover splits the frequency band into two ranges: bass frequencies go to the woofer, and treble frequencies go to the tweeter. In a 3-way system, the frequency band is divided into three ranges. The middle frequencies are sent to a third driver commonly referred to as the midrange.
4 way. More speakers, more sound. think of it as surround sound.
ly/lx<2 is one way slab as for as two way is concerned ly/lx>2
difference between photosysten 1 and 2
They are the isotopes. Because of the difference in the number of neutrons by 2 they have been named that way.
