    I spent a lot of time today learning the many nuances of the BFD, I've reached the point where all the hard work is done now and my room modes have been defeated. I'll do a more in-depth review maybe tomorrow but I can tell you now to believe the hype. I now have increased bass but the sound is even cleaner than before, I made some startling discoveries about exactly which frequencies were causing boom in my room, once these peaks were tamed I could turn the sub's volume up but still with less room boom. Even sub stressers like The Haunting or U571 were clean as a whistle at very loud volumes, during The Haunting my door handle was causing a right racket, I had to tighten the screws down to the max just to quieten it a bit :eek:

    The results were even more improved for music, all will be revealed in my review.

    P.S - Is there anything specific anyone would like me to cover for the review that's not been covered on another site, just let me know.

    I wonder if this thread will remain open long enough to see any replies, time us members started respecting each other's views even if we don't agree with them, just my 2 pfennig :)

    Glad you're pleased with your purchase. Have you set up a house curve?

    Thanks for the update, sounds great.

    My 8024 hasn't arrived yet. :(

    I know my room is crap, so makeing some improvements shoudn't be difficult. Once I figured out the rooms problems I'm also going for the acoustic treatments.

    Yep, I looked into just what that term meant when I first started playing with the BFD and I've now managed to get a pretty darn good curve, I'll leave the pictures for the review though :)

    Apocalypse,

    Please give me all the details,
    IE how you use it exactly, how you connect it up etc.

    I think its just what I need in my living room.

    Many Thanks
    Bry

    This is a very interesting topic. Both Apocalypse and Jeff: I would love to hear as much about your Behringer experiences as possible.

    For anybody interested in the BFD you can download the BFD simulator software, this is based on the previous version of the BFD (20 bit dacs instead of 24 bit), the operating function is the same.

    www.behringer.com/DSP1100P/dsp1100.zip

    This will allow you to graphically see how the BFD works. In a nutshell, you use an SPL meter or some other measuring tool to get the response of the room an then set up a mirror image of the response on the BFD thus cancelling out reflections.

    There are limitiations, for example if you are taking readings and are in a 'null' position (the sound is arriving from two or more reflections out of phase) then you cannot correct for this using a BFD because no matter how much you boost the signal to correct the 'null' the reflections still cancel each other.

    Have fun.

    Apoc,
    Is the "correction" position specific? My frequency/SPL levels vary by listening position, i'm just worried i'll smooth the room for one loaction but bugger it up even further for the others. Apologies, if this is covered in the BFD web site.

    I've set it up for the sweetspot where I sit, however I have noticed that there is less room boom in other parts of the room as a result. Bear in mind that this unit is designed for PA systems/concerts so it's crude in it's approach to Home Cinema but it nevertheless gives excellent results for it's price.

    Review should be done for this evening all being well.

    JSW & NicB, I'll give mucho details on how it works but in the meantime you can look at this site here

    What method did you use to measure the frequency response? Something like a PC connected to a microphone, or just an SPL meter and test tones?
    I hope to be playing around with a digital parametric EQ in a few weeks, but haven't any experience with them.

    Glad to read your first impressions are so positive!
    I checked out my system with the test tones on an earlier thread & found a big hump around 50Hz. :eek:
    I moved my sub & main speakers all over the place but it didn't abate :(
    I guess it's just the shape of the room.
    I'd always thought something wasn't quite right when watching the bit from the Matrix where Trinity is running across the corrugated iron roof, way too boomy!
    Thanks for keeping us abreast & I look forward to your review :D

    Cheers, Paul
