Well, now I know what these things are capable of - at least some what. I've had a G25 for a year, just added a second two weeks ago. I ran Audyssey but have always had trouble w/ REW. After spending HOURS trying to get it work, I listened to
and got a mac to use...I might return it, but maybe not after using that thing. REW was totally hiccup free. Within 10 mins, my sweeps were done. Now I just had to connect the Mini DSP and get that situated. I was clueless, so needed Gregs
) help setting it up...dudes a genius. I may still do some tweaking, but attached pics show the before and after (or after and before - purple line is new graph). Because I spent so long on this, I haven't been able to do a ton of testing - but WOW what a difference. Literally night and day. I have significantly better bass and very low MV. I just watched a movie at -30 MV w/ the Mini DSP gain at -2 and the bass could still be felt. I love it.
Only issue we had - and I spent 4 hours troubleshooting this....when I ran the subs directly into the Marantz 8805 via XLR, Audyssey set the trims at -12. When I went into level test them, I swear I could hear/feel them. After running the Mini DSP + REW and then Audyssey I noticed the bass was significantly weaker. So, I went to test levels, and I could BARELY hear/feel them. The trim for "one" sub was now -6 but it felt much weaker. Enrico was stumped, as was Greg. Nobody had an answer. Finally, I just cranked the volume knob on the subs and tested tones at reference - ut read at 85db. Perfect. So I guess my question - have any of you experienced any gain attenuation when using Mini DSP? I had to turn the volume knobs from 11am to about 3pm. Wondering if the XLR to RCA adapters I'm using are causing a loss too? Either way, its fixed now! Just so odd that during Audysseys initial subwoofer test (keep the icon in the green area) it picked them up and said they were loud. Then during content and test tones they were inaudible. Oh well!
Couldn't be happier and I now realize duals were 100000% overkill for my room. However, I don't need to crank the MV as high now, as the room is filled w/ cleaner, deeper and tighter bass.
