@dweller I bought 2 JL F112s that both died at different times while I left them on overnight. I’ve never had that happen to any other sub. Also both JLs I had some pretty audible humming coming out of the drivers, which to me is a sign of either cheap electronics or too much internal amp gain. While I've had a few other subs that hummed slightly, if you put your ear right next to them, nothing like JLs which you could hear from several feet away.
I think Rythmik and SVS are probably the two best names out there. Velodyne and JL in the past were great if you wanted excellent performance out of a compact sub...but I believe big box retail companies overcharge and also skimp on quality parts typically. Most retail companies charge multiples more than internet direct companies and have parts that cost only a fraction as much at the same time--publicly traded companies are driven by short term profit to placate shareholders.
