Hi Nelson,
That is great!
Just to make sure, in a current DSP setup. each freq band is attenuated/boosted as follows, which I want to be sure is possible:
Hi(>5kHz): -13.5dB, Mid(510Hz-5kHz): -17dB, Low(125Hz-510Hz): +8db
I also would like to know the cost difference between 12,18,24 dB/oct cutoff slopes, and how much assembling work is left for me to do
Can I then obtain a quote of the cost +shipping to Japan to accommodate a stereo 4way xover with a cabinet and a power source? A manual explaining how to select each xover freq and levels would be also great.

There is very little cost difference between the various slopes -
essentially 1 cap and 1 resistor per channel per slope. The caps tend
to run around 50 cents.
The gain issue is larger. Probably you should consider a X10 gain stage
for the bass
The selection of the center frequency of each pole is just a cap value -
this will be clear when the kit comes out.

Nelson-san,avdesignguru-san,
Thank you for replying to post # 546. Sorry for the late reply.
I received the ACN-PCB from the store today.As usual, it is a beautiful.
For the 12dB / oct network I need, I need to bypass some, but is it correct as my pic?
I am not confident that R17-20 is unnecessary.

If you purchase a PCB from the store (The diyAudio Store - DIY amplifier kits, chassis, and parts), the cheapest shipping cost (DHL Parcel Direct) to Japan is $ 15-20.

Regarding a 4-way or 5-way, I don't know wether to cascade or not. Previously I heard it is better to move things around on several boards. I prefer waiting for a version with more channels. From what I heard before, EQ might not be the best idea with a 4-way or 5-way, since this is analog and the signal will be too weak. I was hoping I could amplify the signal enough to make it work, but line level signals might be too fragile. Any thoughts on my confused ramblings?

I think the LOW-OUT is correct but the HI-OUT needs output resistance to ground. See attached.
