BFD + Dayton Yes, this is a cross post from AVS. But I'm sure everyone here doesn't go there, and there has been tons of talk about this over here as well, so I thought I'd share twice. Anyway, got the BFD yesterday, hooked it up and went to town. After 2 hours I had the attached results, the BFD is flatter pink line obviously. Dayton is now moving much more pant leg than it ever has, actually might be for the first time. I calibrated it to 80db as it was after midnight and the woman was asleep. I'll probably go back and do it at 90db, as I am stunned that there is anything below 25, granted only to 22ish, and I don't really expect that to perform very well at higher SPLs. I used 5 filters, 3 cuts at 31, 40, and 70 (roughly and differing widths and cuts) and a 3db boost at 22 and a 5db boost at 56. I'm going to revisit that 5db boost, as I think just maybe, I caught some distortion there this morning when I had 30 secs to run the Sauron sweep from FOTR. Given the things that were rattling in the room last night during the plotting, it could have been something in the room however and not the sub. Overall I'm very happy with the BFD, with snapbug's write up it's a breeze. I think I was setting my first filter 20 mins after I got it out of the box and I had to plot the room before I did that. I am convinced though, that if I get the Dayton flat to 22 at higher SPLs I'll be needing a new sub as I'm sure she'll crack under the strain. Oh this is in a 10X~14 room with an open doorway, Pio 1014, all measurements done on Sub only. Sub is corner loaded about 8ft from the listening position on the front left. There is definitely more detail now, and hopefully I'll be able to actually listen to a few things soon to follow up with that. Test Tones don't really make you go wow, and 2 minutes of Fellowship close to reference and 5 minutes of the Matrix at 80db isn't very satisfying lol. Plus the MCACC needs to be run again... I do so love that Pio Pink noise. Hopefully, after tonight I can come back and say, "wowie wow wow wow." After I take a nap... BFD kept me up all night, but I'm sure it was worth it.
