Question: What's the major difference between CQ76B and CQ76?

Answer:
CQ76B was designed for our DDQ8-2 new type woofer to build large size 2-way cabinet at first. It has wider diaphragm and bigger back cavity for the purpose of extending its low-end freq limit(crossover@1000Hz & THD < 1%) and matching bigger calibre woofers(12-15 inch traditional woofer with rubber or foam surround, etc). What's more, when it works with our patented woofer DDQ8-2 (crossover@1000Hz) in a large size box (sealed box with a 140L volume) it will give you a perfect 2-way Hi-Fi system. But this achievement was acquired at the cost of high-end freq limit. CQ76B could only reach to 28000Hz.

CQ76 could work at 1500Hz reliably(it could match with our DDQ6-2 or 8~10inch traditional woofer for most middle size home 2-way Hifi systems) and its high-end freq limit could reach to 32000Hz.
