Hello forum,
I've been trying to create my first graph on the SVS 25-31 and ran into problems. I've set my receiver to the reference level (75db) and started playing the test tones. However, the receiver kept on shutting off on the 32Hz tone. I lowered the volume to -5 below reference and was able to run test tones until I hit 45Hz tone and the receiver shut down again.
So, eventually I had to put the volume to -15db below reference to be able to play the test tones. But still I could only get to 125Hz when receiver shut down again. If I lower the volume more I'll be able to play the last 3 sweeps but I wouldn't be able to see them on SPL since these sweeps show below 60Hz.
Now, my subwoofer out level is set to -5 on the receiver, all speakers are off, receiver is in stereo mode, crossover set to 100Hz. My receiver is Denon 3802 (110W) and I never had any problems with it.
The above graph was taken at -15db below reference and shows values from 20Hz to 125Hz. What do you guys think? I just got my BFD yesterday and plan on playing with it some time next weekend. But before I wanted to get your opinions and suggestions on how I should approach it with this response. So far I've been doing a lot of reading on this forum and probably have read every single thread on BFD and house curve. However, I think that each graph is pretty unique and there're many ways to approach it. So, I wanted to get some help from more experienced people especially Wayne and Brucek. Your opinions are welcome.
Thanks in advance,
Ruslan.
