Bill, that song does have midbass presence doesn't it? On my computer setup it sounded great, I'm going to try it in the car for sure. That lead singer rivals Morphine for vocal reproduction quality difficulty. It's a shame Mark passed, I miss that band, and I was still a kid back then. This song (see video below), is a favorite for low-end tuning, the low octave saxophone and, yes, that is the 2 string slide bass which Sandman made famous. If your system can't reproduce the end vocals with clarity, it means you have too much noise, too much gain overlap, or lower midbass/midrange blending issues causing muddiness, so just read the lyrics lol.
Why would I need time alignment anyway? My front door midbasses and rear fill midbasses are, what? Three feet apart? I doubt that will cause any issues, I don't see anything overpowering either considering the front stage I see in some cars. I may try it in 3 configs: Full set in the rear, midbass in rear mid/tweet up front in 3D config, and mid/midbass rear and tweet up front.
I really hope Bill and I going back and forth over power figures and specs doesn't put people into the mindset that I'm a know-it-all chump who spends money on trash. Bill and I have individual opinions, and are into the hobby enough that we question any manufacturer's build quality. Even if my amps only do 85% rated power, they are doing much better than 85% of what's in most cars. Plus, these amps, I bought them as a shot in the dark. If I don't like them, they go back. I know Vibe is not a familiar brand, but there are countless other small-name, or uncommon companies out there making great gear too. These speakers sound fantastic at retail, at $90 a set they sound like gold. I've auditioned middle of the road studio monitors and several sets of home and car speakers costing 10x or more what these cost with less accuracy and listenability. My only gripe is crossover size and construction quality of the boards, even then, I've owned worse. I'm not going to spend billions on this old car, which is why I'm not going to do any glasswork for kicks or pods either.
