Guys, this is one of the first times I've tried this. So if the image doesn't load.. or is too big to d/l, etc. my apologies. I took a screen shot of an overlay from ETF of some low freq response tests I ran today. I pasted it in Paint and saved it so I could upload it to a web page for posting here. I'm sure there are easier ways to do this and make the file size smaller but that's beyond my knowledge at this point. I couldn't get an lf.etf file to upload to the page. Which corner would be best to put the sub in for eq purposes? I'm guessing the right front corner (blue). The red line is the left front corner. Interestingly enough, I first had the sub in the RF corner. But after running some spl/Avia/VE tests, thought the LF corner would be better. I dial down the sub input by ~5 dB to get the same spls if I have the sub in the LF corner vs the RF corner. This seems confusing when I read it. Hope it makes sense to you.
