First, I hope you're reading Outlaw\'s manual - it's a bit easier to follow than the Velo manual. Second, I'd set the gain/volume on both to around 4 or 5. I'd set the crossover frequencies as high as possible or just disable the crossover if it's an option - that'll let the receiver's 80Hz crossover take care of things itself. The UFW-12 is rated down to 20Hz in-room. Have you been running the VTF-3 with or without a port plug? You might put in the plug for calibration, I suppose, although unplugged will produce a higher SPL level. Lastly, I'd set the EQ level on the UFW-12 to 0 for now - no reason to muddle things when you're getting ready to EQ through the SMS-1. You can always use it if you find a frequency that you want to deal with (using the SMS-1's display to give you specifics).
