One thing to consider is the FMOD is at a 12 dB per octave crossover slope and Hsu uses a 24 db per octave crossover.Just something to ponder.

In my stereo set up I use a Outlaw ICBM which works great.I tried to use the Hsu high pass filter,but it introduced a hissing noise to the tweeters of my M80s.When I asked Dr Hsu about this he had said it was because the 80s had such a high sensitivity rating.I sent the high pass filter back.The ICBM introduces absolutly no noise to my set up.
