Tanya: Fullrange Concentric vs split mid+tweeter

Hi rekan modcomers,

Baru saja nemu produk full-range FOSS CONSENTRIC CST 3.
Ini midrange 3", ditengahnya ada tweeter 1".
Menurut iklan, awesomeness nya adalah:

• can reach a frequency of 100Hz - 20 KH
• with the tweeter placed in the middle, makes this blend as speakers fullrange speakers. Only difference, the full-range speakers prone to roll off in the high frequency area.
• making the arrival of the tweeter and mid unison sound to the ears.
• known as one point source technology, for achieving coherence between the two speakers sound, unlike the usual split mid-range + tweeter system.

Harganya lumayan, setara dengan midrange+tweeter mid-end.

Jadi penasaran, apa iya lebih bagus ditandingin dengan split mid-range + tweeter ?
