其實就是612箱体，單元是8G，但內部分頻才是重點

為什麼說分頻器是重點，因為外表平平無奇的分頻器，但內部線圈是少見的高頻蜂房線圈斜線繞法，自製較麻煩

网络资料：
The size of th cabinet s 30"x23"18"，cabinets are only 5.6 cu ft and the actual speaker chamber is only 4.5 cu ft. The bottom 5" is a port that goes to the back of the cabinet with a 5.5" opening to the speaker chamber, a 17" x 4" opening on the baffle.

So I finally came up with a pair of Audiotechniques Inc. Mastering Labs crossovers.

Based on a few measurements and tracing my way through the units I can say pretty certainly the schematic that has been floating around the internet is wrong, very wrong.

I've got to dig into it a bit further, but so far L1 is a tapped inductor, but only uses the tapped portion, L2 is much greater value, C1 is smaller, R3 is non-existent, ATT1 is a greater value than listed, L4 is a tapped inductor but the tap is not connected, and L5 is much smaller than listed...

I'm going to fully dig into these and come up with a correct schematic.
