Following on from my being nominated as forum Guinea pig in the previous SOS thread, the SOS I ordered arrived last week. I've been busy so the first SOS to be exported from the USA has only just been set up and run.
The result? It works!
Calibrating the unit is a breeze. Connect it between the amp and sub, turn it on, plug in the mic and flick on the calibrate switch. Hold the mic where your head will be and a minute or two of built in test tones later it's all done.
Just to make sure I took a couple of before and after measurements to see if it was really working or my imagination.
This graph is with the sub in the corner (Yellow: no SOS)
and this is where I originally decided the sub sounded good (Pink: no SOS)
It has done a good job on the sub in corner (and was faster to calibrate) where the room modes were larger. The second graph it took at least twice as long to work it out.
Both times the calibrated bass was a clear improvement over the uncalibrated but the second one was more subtle. So it does improve the sound but now we get to the main problem with the SOS, including taxes it was £260.
Is it worth it?
I can only say maybe. If you are happy to play with a BFD then it's clearly too expensive, if you aren't then it's still expensive but worth it. Whether the SOS being an analogue filter makes it sound better, I just don't know
