Martice -

All that has been said is true about the ICBM and 2 channel analog otput from your pre/pro - Set the mains to large and let the ICBM cross it over to the sub at the point of your choice.

Also, the ICBM has a front panel sub level control. If you are used to reaching down to the sub to adjust sub output volume, those days are gone. As an added bennie, the ICBM has a front panel LFE mix control. Say you are listening to a 5.1 or DTS DVD and you adjust the sub volume to where the output from the L-R speakers, which has been redirected to the sub, sounds good. However, the LFE output is either too strong or too low to blend well with the other bass. The ICBM has an LFE mix control that will let you adjust the amount of LFE in the total sub output. Then when you adjust the sub output, the ratio of LFE to overall bass stays the same as the overall sub volume increases or decreases. Sounds complicated, but very intuitive, once you start tinkering with it.

Needless to say, I like my ICBM.
