    I have heard that some people a BFD 1124 not only to help achieve flat subwoofer response in room, but also to prevent higher frequencies from reaching shakers. One channel of the BFD for the subwoofer and one channel for the shakers. Will this work properly? Or do I need an F-mod rca crossover for the shakers. Looking to have the shakers as 50 hz and below.

    thanx

    You may be the same guy that posted here.

    If not then yes you can do what you are wanting to do with 6 filters.

    I'm thinkin' he doesn't have the crossover available and further may want to level out the response of his shaker. The BFD is not used to destroy feedback in this case... it is typically used as a parametric sub eq.

    Yep, I am familiar with what the BFD is used for. I am suspicious that the subwoofer output of my receiver is either full range or has a rather shallow roll-off slope. Perhaps there is a bit of a crossover (probably 100 hz). Perhaps the combination of the receiver crossover, the natural roll-off in the response of the bass shaker and the BFD filters will combine to give me the results I want. I would like a BFD anyways so I can fine-tune the room response of my subwoofer, so I may as well make use of the second channel [​IMG]

    Sorry... I didn't mean you didn't know what it was being used for. It sounded like Nhoj might not understand what we are doing with it.

    What receiver do you have?

    Also... have you seen this thread ... post in it showing some interest if you will... the more we can get the better chance we have of getting it through. With built-in crossover it would do the trick for you.

    Hey you just sold a set of PSB Image speakers. I was tempted, but the trip across the border would have been problematic..and besides, I already have PSB Image anyhow...although I would like to try the 7PT or the new Image Towers, and the bipolar surrounds...anyhow, I will check out that thread.

    My receiver is a Marantz SR 8000. I like the sound for music [​IMG]

    Doesn't the amp your running your shakers off of have a hz setting?
