A question on a B&W high pass filter


I have a B&W 800 series variable high pass alignment filter for my 803 matrix speakers. I have never used it & wondered if I need to? What would I be expected to hear? Or should I just sell it & forget it? Also, what is the thing worth? New, in box. I never hooked it up since i had no idea of why I would need to. If you can help me understand this question, please answer. Thanks.....

I 'm aware of the Anodyne unit, but have never seen one for sale. I'm currently using the Listen Up Maugham Box for my 801 SII, haven't updated my system picture though. Not positive, but I believe they only made it for the 801 model.

Oddly enough, when I got my 801's, the High Pass Filter came with the speakers, although they were supposed to be an extra. However, I was given the Filter for the 802. I used this off & on for years.

When I got the Maugham box, the improvement was subtle but noticeable-deeper, tighter bass, with an improved sense of bass tone and notes. I miss that extra depth without the filter.

Good luck.

They are not noisy at all. Turn volume up with nothing playing,quite.and work great

I have one that  has XLR and is labeled

Matrix 801

Professional

High-Pass

Alignment

Filter

When I open them both up,the Pro model has more than twice as many components in it

 

Anyone see this one?
