I finally got Avia along with an SPL meter for Christmas, today I decided to play with it a bit, but did not do a full calibration. One reason for that is my Sony receiver sucks! It does not allow you to adjust many of the things needed in order to do a proper calibration such as sub crossover level or the loudness of individual speaker levels. But I did get to find out where my subs level should be, and it ended up being on the third hash mark (out of 7) or at 10:30, however you want to look at it. Now the funny thing here is that is where I always used to set it when watching movies, sometimes a bit hotter at 11:00, I found it pretty surprising that I had my subs level correctly set by ear, but that was good to know. I was also happy to find that the sub is pretty flat in my room, response is pretty flat from 100-60 Db’s, it does have a big dip at around 88 Hz though, then once it goes below 60 it gets considerably louder than the 100-60 Db range, but from 60-30 Hz it pretty much remains within 2 Db’s with a 4 Db slight bump in the 32-38 Hz region (which is very deep BTW). The once it goes below 30 Hz output drops off by around 4-6 Db, but was surprised to see that the sub has usable output down to 23 Hz. Anyway no real point to this thread, I am just happy that my room does not have anything crazy going on with it and now that I know how to use the meter I can experiment with a few sub placement options to see if they work better. O yeah there are a few pictures of my setup in the link below so you can see where the sub is located.
