My avr is in my sig, but it is a Yamaha RX-A2010. I had given a brief impression on the subs when I first got them setup.
Since then I ran YPAO, not much of difference since I use manual equalization anyway, but I use it for the distance measurements.
I've got these dialed in pretty good. I'm running a pretty flat frequency from 20-80hz +/- 2db. I don't use rew I've thought about it, maybe one day. I just use test tones and a spl meter.
My room sucks with it comes to midbass, 70 hz and above, but these subs actually gave me more output in the 70 region compared to my Velodyne's. But I had to implement the Velodyne's to help out with the output with 80 and above. I'm down about a 1db from 80 and then about 6db from 90 and above. I have an opening to the right leading to stair case. I may get that sealed and place a door there, not sure yet.
Now regarding the sound of the Rythmik I love how clean and effortless they sound. As folks have quoted before me they just disappear until needed and they slam very hard. Today I was demoing Transformers: Return of the fallen. In the opening scene where Sideswipe cuts that Audi in half I felt air from the ports hit me in my face it was literally refreshing lol. I think I had my master volume at -20 or it was -15 can't remember lol.
I may one day add another two but it probably won't be for about a year or so but one day I will. I just love how hard they slam and it still so clean compared to my Velodyne's they seem to lose steam with 50hz and below at about -20 on my AVR with music, but I was able to push these bad boys to -10 and they were still banging out.
Thanks to this thread and the valuable information I gathered before making this purchase, I'm very happy I did. It wasn't cheap and never thought I'd spend this much on subwoofers, but I guess that is a part of the upgrade process. I came from HTIB, to Sony speakers and subs, then Velodynes, now I have these 15" monster's in my basement. I love it!!!
