I ran my first test yesterday on a yet to be named speaker. I chose a simple 500 point test to make sure everything looked good. Took about an hour. Yep. All is good. Called it a day.
This morning I started up the 2000 point test to reduce the error >10Khz. It is about 30 degrees outside. My car doors were frozen shut when I went to run an errand. It's coooooold. Before I left I turned on the 240v heater in the garage and it quickly warmed up to 72°F at the DUT location. Since the garage is insulated it maintains the temp quite well. (It is still at 70° two hours later.) I am currently running the test and it is about halfway through. But now... I am inside, doing chores while the NFS is churning away, producing results. Every once in a while I check up on the laptop running the test via VNC from my desktop in my office (as you can see below).
To those of you who have never spent days' worth of time measuring a loudspeaker you may not understand just how great this is. But, if you have then you know just how much testing speakers drains your time and your literal physical energy (not to mention the mental stress that comes from trying to balance it all with weather, family, and work life). The NFS is gonna make my life so much easier. Not to say it doesn't take time to set things up but not having to be physically outside running from the DUT to the computer 100-something times (for a literal total distance of 2 miles; I measured) is ... liberating. That really is the best word I can think to describe this feeling.
