The advantages and disadvantages of the two speakers are just relative, the following will give you a detailed introduction to their advantages and disadvantages：
Advantages of frequency divider speaker: Each frequency band is voiced by a separate unit, so each unit can work at its best.The extension of high and low frequency is easier to achieve better. The independent intermediate frequency unit can bring extremely high replay quality, the overall electro-acoustic conversion efficiency is high.
Disadvantages: 1.There are timbre difference and phase difference between each unit.2. Frequency division network introduces new distortion to the system.Sound stage, degree of separation and level are all more susceptible, and timbre may be deviated.
Full frequency speaker advantages: 1. point sound source, thus accurate phase.2. The timbre of all frequency bands tends to be consistent.Easy to lead to better sound field, knot image, instrument separation and hierarchy.
Disadvantages: Because the design needs to meet the needs of different frequency bands, the design and final performance of each frequency band will be constrained.The high and low frequency ends of the extension is relatively limited, transient and dynamic are relatively discounted.
