Jason,

I have a similar setup to yours, see my sig line. I have yet to get my system perfected either. My situation is slightly different in that my fronts clearly are not large speakers so I am always employing the sub crossover through the 990.

Having said that I was wondering if maybe you couldn't just use both of the 990's outputs, i.e. run the balanced outputs to your amp and the RCA's to the SMS-1. In this way the fronts get the full range signal and you can use the SMS-1 to control the signal to the sub. Down side of this setup of course is that you would not be getting any of the sub signal from your other speakers, i.e. center and surrounds, which would have significant impact on your HT experience. Personally that would not be acceptable to me, but for 2 channel listening it should work.

If HT is important then I would go back and try the fronts set large and the sub set to LR+Sub. This will send signals from all speakers based on the 990 crossover points. I am not sure whether is sends the full range signal from the fronts, but I doubt that it matters as the SMS-1 Low Freq. Crossover will take care of that for you. Keep in mind that the SMS-1 LF Cross needs to set at least as high or maybe slightly higher then the highest crossover point configured on the 990.

I have my system setup pretty well. I am extremely impressed with the LFM-1 EX it is a real ass kicker! Yet, it can be quite musical as well so overall I am very pleased. The SMS-1 really helped to smooth out the overall low response of my system and was fairly easy to configure although it did take me several hours of testing and I feel like I may need to do quite a bit more before I am satisfied it is at its best.

Now here is a question that maybe Gonk can answer. I sound good on movies and I even have a real aggressive config that will really thump the low end for action movies with a lot of explosions or battle scenes. I have a great configuration for listening to may SACD as well as traditional 2 channel listening of my older CD's. My problem is that occasionally, particularly when I have company, I like to take some of my 2 channel media and play it using the using the 5 channel stereo option. When I do this the Sub output is way over driven. My first thought was to just create another config, after all I have 6, on the SMS-1 with the sub volume reduced. However, it does not seem to be uniform from CD to CD. I can range from -10 to -20 on the volume in order to get it back to a good sound. Any ideas?
