Can I use the Outlaw ICBM this way?

    Hi there,
    My receiver has a fixed crossover of 100hz, and I'm led to believe that this is too high. I was thinking about adding the Outlaw ICBM to handle the bass management. Do you think it will work in the way it's described as follows:
    1) My L/R speakers handle bass down to 31hz at -3dB. The center handles 50hz at -3dB and the rears 55hz at -3dB.
    2) The speakers will be connected to the receivers speaker-level outputs as per normal.
    3) I'll set all speakers to "Large" and the subwoofer to "On".
    4) I'll take the 5.1 pre-outputs on my receiver and plug them into the ICBM's 5.1 inputs.
    5) On the ICBM, I'll set the L/R crossover to 40hz, the center crossover to 60hz and the rear crossover to 80hz.
    6) I'll take the subwoofer output from the ICBM and plug it into my subwoofer, which is dialled to it's maximum crossover level.
    Do you think this will work, i.e. adding an external bass management unit? This way, I won't have to upgrade the receiver (instead I can buy a good two channel amp!) and I'll still be able to use the maximum bass capabilities of my speakers.
    Thanks,
    Mal

    Mal,
    There will be a small area of overlap between the speakers and the subwoofer, which might give you an accentuated response because you've effectively doubled the output. This would be the region between the ICBM crossover point and the -3dB point on the main speakers. It's not a huge region, but it is something to be aware of.
    Try it and see, you can always return the ICBM if it doesn't work as advertised, and just be out shipping both ways.

    Thanks John, I'm hoping that because of the ICBM's 12dB lowpass, I should be ok with setting the bass crossover the way I described... hopefully.
    As I live in Australia, returning it will be a problem, I suppose I could use it as an excuse to get a poweramp as well [​IMG]

    Using the ICBM to set bass management for your receiver can be
    bad for the time delay setting, so if you use the ICBM it's best
    if your speakers are all the same distance to the istener. See
