"Skar and Obsidian like the lows better" What is that based on? Does a bigger magnet mean it's louder? What don't you like about the dcon? Loudest? At one frequency? Overall? No one knows which will be louder in your enclosure alignment, and vehicle. Only assumptions can be made. I'm glad your power is "clean", I hate it when mine gets dirty, and I have to bring out the broom and dustpan. As much as I didn't help you in any way, perhaps you understand my reasoning. Generalities get no where, and assumptions aren't exactly helpful. What you will get is people who like one brand over another, and suggesting it's better.
