Hey Steve, haven't checked on this thread for a bit but your last posted graph looks TONS better. Amazing what a change of position will do for you. \:\)

Good luck with the BFD to finish out the tuning. The guys above gave you the advice you need.

EUREKA!

It was a little rocky for a while, but I consider this graph a huge accomplishment! The learning curve is tough, but worth it now. In my room (especially) i think this sub will probably never do 16hz +/- 3 dB. Maybe that is a somewhat phony stat. I'm ecstatic that I could get down to 20 hz so well though!

Alright I tamed that null right after 80 a bit, because it was bugging me. My XO is at 80 Hz so it should not mess too much, but it bothered me. Thanks all for your help and patience!

Much improved! the down lows are much better, and the rest are much better. I actually haven't watched very much since that, but I will report back.

I don't want to sound like a newb, but I guess I am... What is being used to generate those plots?

I use a program called Room Equalization Wizard, which can be found, as well as much helpful information here:

http://www.hometheatershack.com/roomeq/wizardhelp/help_en-GB/html/index.html

then the use of a SPL meter from Radioshack is what collects the information.

By the way, welcome neon! and let me know if you have any other questions I can answer in regards to REW. I've been slaving over it for a few weeks now and feel like I have a decent grip on it.

REW is a big time suck and way too much fun. I want a GOOD mic just to plot out the rest of the frequencies for no other reason than I CAN. \:\)

Ah, I had seen the mentions of REW and also seen people posting these plot images. Just didn't put those two together.

I didn't know about the BFD until yesterday either. When I read about it I figured it would be a piece of equipment that would cost as much a sub itself. But even the newer model costs the same as my piece of junk sub I bought 15 years ago.

I've still got other things to do and buy before I get to this point, but I'm filing this information away in the back of my head.
