With my 15V I ran Audyssey which came back at -6db, a little higher than I would like, but I didn't want to calibrate again. I then went up 8db on the sub amp itself, then 2db on the AVR trim to bring it to a total of 10db hot. This is without DEQ.
For most of the movie so far the bass was just great. There were, however, a few scenes where the sub had to work really hard with a lot of port noise, granted only for 4-5 seconds, but pretty distracting. I even lowered the trim to -11db with this scene to see what happened, which would bring my total "hotness" of sub at 3db. At master volume -14db, you could still hear some vent noise, but on a much smaller scale. My guess is the scene I'm referring to is around the 15Vs port tune, because as I said, in the majority of the movie I've had no complaints...which brings me to my next thought...
I keep reading on these sealed subs...people just seem to love them! The S3000i looks really intriguing and I like the idea of eliminating port noise all together. If that s3000i can give me the bass I experience now with my 15V, this is a very tempting trial for me. Because of the way our basement is set up right now, I can only do a single sub at the moment, but I know with some saving of money and time I could purchase a second down the road. Would I really be giving up much of the lower bass with the S3000i?
There aren't a lot of 15V owners here. Glad to see another one!
So, I am curious how you know you added 8db on the sub amp. My 15Vs are just dots. Did you just count dots, or something? It would be news to me if you are able to convert the dots to db. Based on my experience with two separate 15V setups in my house, I recommend you try this:
1) Use only 1 RCA input on the sub (do not use a Y connector to use both inputs). Gain knob between noon and 1pm. Delay set to minimum. Crossover set to maximum. Room size set to maximum.
2) Run audyssey. Hopefully it sets the sub trim between -11.5 and -6. Honestly, no big deal if it comes back -12 (or whatever max negative is in your AVR). Set speaker crossovers no higher than 80. I also prefer to lower the LPF for LFE down a bit.
3) Turn on DEQ. Turn off DVOL (actually I like DVOL for tv watching).
4) Test it. Add heat to the sub trim to your liking. You may only have to come up a couple db if audyssey brought back max negative. I go 6-8db hot with DEQ on, depending on content, typically watching at -20mv at most. The sub just pounds. Can't imagine watching any louder than that in my ~1980 cubic foot sealed movie space. I played MMFR through it for the first time the other day and it was awesome.
Also, with DEQ on, make sure your reference level offset is 0. That is the default, so it probably is.
