    Hi All,
    After a bit of reading on room / subwoofer interactions, I picked up a Behringer Feedback Destroyer Pro from a local Music shop on friday. Yesterday I spent a couple of hours setting up the BDF with my two subs. You can see the results in this graph. As you can see I had three large humps, while not a 'house curve' yet (a bit more tweaking is required), the BFD has greatly smoothed out the response of my two subs. While the low end slam is still there, the big difference is the increased clarity in the mids to highs as the humps around 56 and 100Hz were muffling the higher frequencies. I never realised this until I heard the difference. You can take the BDF in or out of circuit with the press of a button, so its easy to compare the sound before and after. I'm a newbie with the BDF, but so far the results are very promising. I'll introduce a 'house curve' by raisng the frequencies (reducing my current cuts) < 40Hz when I get some quite time (i.e. wife and kids aren't around). While the BDF has a bit of a learning curve, this guide is invaluable. I'd really appreciate if any any of the more experienced BFD users had any suggestions on how I could improve my graph further.

    cheers,
    Stephen

    Well,
    I got a chance to do a bit more tweaking and added a 'house curve' through a different preset on the BDF. I now have a flat response on preset 4 and a 'house curve' on preset 5. Both these graphs are subs only, no mains. You can also view the combined response of both subs and mains here. All I can say is Wow! While a flat response increases clarity, it lacked a bit of low end authority, adding a 'house curve' has returned that authority with a vengence. Watching LOTR and Star Wars II, I was grinning from ear to ear.
    I really can't recommend a BDF highly enough for anyone wanting to get the most out of their sub(s).

    cheers,
    Stephen

    Thanks Ian, at the end of the day its how it sounds, not what the graph looks like, and I'm very happy with the results.

    cheers,
    Stephen

    I always think a broad grin is really the best indicator of success in setting up a sub. Excellent curve! Enjoy! :D

    Looks excellent to me - a very good test is to play the sine sweep on the THX optimiser disc, hopefully you won't hear the volume change that much as it goes down. :)
