Whats the difference between 2-way and 3-way speakers.?

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!

2way are usually Low and high sound 3way are usually Low, meduim and high sound
