and how good and ultimate speakers.
2way are usually Low and high sound 3way are usually Low, meduim and high sound
It is actually quite simple. Your music could contain sounds from 20 cycles to 20,000 cycles. 2-way speakers reproduce the lowest and part of the middle range through one coil, and the rest of the middle range and the highest sounds through another. A 3-way speaker has the low sounds (bass) through one coil, the mid-range (which includes the average voice) through another, and the highest sounds through a 3rd.
2 way speakers are going to give you mids and highs, whereas 3 ways will give you lows, mids, and highs all from one speaker like 6x9's in your rear deck for example. If you have the means I suggest Boston Acoustic, Infinity, or Polk Audio speakers
2 way speakers consist of a small woofer and tweeter! 3 way speakers consist of a small woofer, mid-range and then a tweeter! 3 way conponent speakers system give you the best sound!
