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.

Mac2c, I dont think the aligmnet filter was made for your 808's as thy were only made for the Matrix 801-805's =(

Mac2c, the alignment filter is definitely not for the 808. The 808 by itself has got a free field response of ± 3 dB 30Hz -20 kHz. You don´t need a filter for these ones. I ma using the filter now on my 800 matrix system but I bi-amplifie so it doesn´t hurt the sound at all. Actually it is a must.

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?

Older thread but I just picked up a filter for my 801 matrix S3 - it improved things substantially. I did not use the preamp tape loop for connection but put in between the amp and preamp.

Greater solidity, more definition in the lows. Much nore enjoyable. The part I really cant get over though is that any woofer movement on LPS has now almost diasappeared to the point I don't need to use the preamp filter setting.

I am sure there are many enjoying this high pass bass filter and we usually only hear more about bad experiences "like everything else" - this kept me also from trying it out. If you have any matrix 800 series speakers recommend giving it a try hooked up between amp and preamp. They do come up on ebay.
