Mr. 7up...This is 3 1/2 way design is quite interesting and not to be seen too often. Do you know what the advantages of having two woofers with different cutoff corss-over frequencies are? How does it affect the actual listening? How much worst does it do the impedance due to the addition of parts..? Is it worth it to do so at 180 and 220hz?...It is so close... Technically, it is nothing special, could be done easily..just wanna know why lol..
You 玩EQ? O..boy.....I am the opposite lol....let me try to figure out about the cross-over...let you know if found..haha. My music teacher uses a many many band eq...cuz me headache hehe.."響度、沖擊力" 沒有記錯..where the kicks and punches from...
