About a year into this hobby, I upgraded my Onkyo receiver to a Denon. I noticed an improvement, but something still seemed wrong. Did some acoustic treatments in the room. Helped...still something wrong.
Finally in 2011 I brought the Bravus 10D into Aperion and they ran tests. They reported back to me that "they match very closely in terms of their frequency response in terms of dB vs. the frequency that they are producing" (mine versus a test model). I took it home and went back to tweaking and adjusting settings.
Fast forward to now and we moved to a new home in a new state. I have a larger theater now (21x21) and while I calibrated the theater well, the sub is driving me nuts. I went to YouTube and played the following frequency sweep:
At "normal" volumes it sounds good to about 50hz but then becomes very distorted. If I turn the volume down it gets to about 40hz but anything below that sounds horrible (while the frequency drops, it gets a high pitched squeal). I played with the sub volume and the receiver volume...can't get anything below 40hz to sound good.
I'm heading to Portland this Monday and was going to bring the sub to have them test it again, but after running this sweep and reading a bit online I'm realizing that perhaps I've pushed this little sub way beyond its intended limits. Being HT and gaming dedicated, I want that deep rich bass. And unless there is a slim chance that my sub is actually defective, I'm realizing the 10D won't get me there. Soooooo...2 questions:
- I'm open to suggestions for a good quality sub for dedicated HT and gaming...in a dedicated room that is 21x21. Happy with my other Aperions I was looking at the 12D, but wonder if maybe I should broaden my search.
- I wired the new theater for dual-subs but haven't done much research on them. For a room this size, would I hear a noticeable difference having duals rather than just one really good high-quality sub?
Side note: I'm looking at the 10D online now and it looks like it has different specs than my 10D from 4 years ago. Mine is 300W, the current one is 500W. Current frequency response is (- 3dB) 27Hz - 180Hz (- 6dB) 25Hz - 200Hz while my version is (- 3dB) 30Hz - 180Hz (- 6dB) 26Hz - 180Hz
Appreciate any thoughts. Thanks all.
