I recently purchased the SMS 1 and got a chance over the weekend to play with it. My playing has raised a number of questions I haven't been able to find the answers to. Any help would be appreciated. Other equipment includes 990/7700/LMF1/Klipsch RF7's, RC7 and RS7's.

1) During manual setup, the instruction book says to mute the SMS and adjust the audio level on the preamp to a comfortable listening position. All the speakers are set to small with crossovers set at 80 (front), 80 (center) and 100 (surrounds). While watching the graph on the monitor, I noticed that the frequency response starts at about 30hz which is the low end of the RF7's. I thought by having the crossovers set at 80hz that the graph wouldn't start until the signal hit 80kz. Does this mean the crossovers are not working?

2) In Auto EQ mode, the SMS boosted the 20hz signal to +6. Is this dangerous for the sub?

3) This is probably a 990 forum question, but I'm going to give it a shot. I like the Klipsch speakers, but they are unbelievably bright. Is there anything I can do with the 990 to tone the horns down? Anything out there like the SMS to flatten out the higher frequncies?

1) One thing occurs to me. What mode do you have the SMS-1's input on the 990 set to? You'll need to be in stereo, as bypass will create a scenario similar to what you are describing (it will bypass the crossover, sending a full-range signal to the RF7's).

2) That's probably not an unusual thing to see (my SMS-1 did something similar in auto mode) because of the LFM-1's roll-off. I don't think it's actually dangerous, but it probably wouldn't hurt to turn it down a few dB just to be on the safe side.

3) Others may have some better ideas on this one, because nothing occurs to me except perhaps some room acoustical treatment. Do you have a particularly hard room (hard wood or tile floor, minimal upholstered furniture, few curtains on windows, ...)? If so, the room may be accentuating the "brightness" of the Klipsch's horns - in which case something as simple as an area rug could start to help.
