Looks like the ICBM has only one choice of high-pass x-over slopes: 12dB/octave. Low-pass is either 12 or 36dB/octave. I'd like to see a 24dB/octave for each. I'd also like to see LR filters. For those who have an eclectic array of speakers, this would be more useful. 12dB/octave high-pass for sealed boxes, and 24dB/octave for speakers that can go more than 1 octave below cutoff. A 24dB/octave low-pass would then match perfectly, if they were LR filters. It would also be nice if this was selectable for each speaker.

I'd also like to see a better selection of corner frequencies. Like 40,50,60,70,80 Hz. How many SACD/DVD-A owners using speakers with 120Hz F3's could there be?

I understand the challenges of a $250 product that does everything, but making a more advanced version, even at a higher price, would be attractive.
