SH, having calibrated exactly as the manual and you described above brings up a question I'd been meaning to ask.
My Subwoofer is a passive 4 ohm 12" driven by a bridged Adcom 555II. This amp is rated at 200 Watts p/ch into 8 ohms. Now I cannot find the manual to give exact figures but you can figure this sub should be getting gobs of power right ! I figured the amp may very well complain about this load, even though it is claimed to be stable into 1 ohm. It is not distressed at all ! Hell it doesn't even get warm, which makes me wonder if the thing is working correctly in bridged mode. It is designed to be switched from Stereo to mono and 2 channel to single if one so desires. I used it for years without fault in stereo mode.
My question is this ... Why do I have to completely max out the gain within the 950's speaker setup for the LFE, and almost max out the gain on the ICBM also, to get the same db reading as all my other speakers ?
I would have thought this sub setup would have had to be tuned below the others by a considerable amount, so I'm missing something here !
Perhaps the 950's test signal is not optimized for subwoofer response (ie. too high in frequency) I think I'll draw up a response graph using a test disc. Could be a 20-25 hz signal might move my walls and otherwise detract greatly from the spousal acceptance factor that is already teetering somewhat !
