Hi all ,loving this unit, my question is:if I have the level of the test tone thru my fronts at say 80 db according to the radio shack spl meter what should I set my sub level at? 80 also, I know this sounds like a dumb question. but i'm just wondering the proper way to do it. I have my subs betwen 1/4 and 1/2 like it says in the manual and with the test tone on it kind of flattens out around with the volume at 30 to 34 on the sms1. does it sound like I'm doing it right?

If you have the volume of your processor up so that the mains are showing around 80dB or so on the frequency response screen, then all you need to do is keep the response curve level to the left and you'll end up with the sub adjusted to the correct level. With so many places to adjust the sub level (sub amp, processor, and SMS-1), it does get a bit confusing, but I simply set my sub's volume nob at around 1/2 and set the sub trim on my processor around 0dB (I had it at -4dB previously), then left it up to the SMS-1 volume control to handle the rest.

thanks Gonk, but my question is, should there be a certain db level that the subs should be, my thinking is fronts 80 db sub 80 db or should I just adjust the sub volume to what i like{I like good bottom end} be not boomy, but I want the subs to kind of match the fronts, I mean I went thru the response chart in the eq and the fronts are pretty good down to 40 hz.

If the mains are 80dB and the curve is flat, then the sub is 80dB as well - that's the nature of the curve. Having said that, I'd suggest calibrating to 80dB and adjusting to taste (up or down).

Thanks again Gonk thats what I thought, By the way how are you making out with your unit

I'm quite pleased with mine - even got a review up here /

very informative review, hope I was a bother with all the questions

Nice review Gonk. So is the slope supposed to be set at 0 if the SMS crossover is off then?

If I remember correctly, as soon as you set the crossover to "OFF" the slope also reads "OFF".

gonk,

did you turn off your amp at all during the tuning process in order to see just the freq curve of your sub? i didn't realize my sub still played a lot of material above my 80hz crossover that i had set for my mains.
