B&W Variable High Pass Alignment Filter Setting.

Hklai:

According to my B&W 800 Series Variable High-Pass Alignment Filter manual, the filter has 10 switches (numbered (from bottom to top) 1 through 0, for each channel. The Matrix 801 speaker switch position for each speaker is listed as follows:

Switches 2, 4, 7,and 9 on. The other switches are in the off position.

The positions for the Matrix 804 are listed as:

Switches 2, 3, 5, 7, 8 and 0(10?) on.

I have B&W 808's which are not listed in the manual. If someone knows the correct positions for these speakers, please post.

Thanks guys for your responses. The owners manual for the 808 in the discussion of Environmental Controls says, in part, the following:" However, some attenuation of the bass extension may be desirable, and an electronic bass control unit is in the process of development." To what does that refer?
