Easier maybe ..... Too bad the Hi F response & imaging will suck with the tweeters down there.
What does placement have to do with frequency response? Placement has nothing to do with tonality. What you smokin?!?
And imaging in the NSX is difficult to get right anyways. I have yet to hear one that is as good as a decent car set up with good kick panels. There is no room for kick panels in the NSX. And for people like me that won't cut into the door panels or modify them with pods etc, this type of speaker baffle is really the only thing that makes sense in an NSX. Myself, I just went with some braxials and it turned out pretty decent IMO. BTW, I made my own baffles, so I don't care which of you sells more either way.
I'll copy/paste what I said before when the idea of placing tweeters higher up or on the dash was raised (and now in reference to your statement of the low tweeter placement being the poor imaging culprit):
"Good imaging comes mostly from the location and direction of the MID driver. Keeping the mids in the stock locations will not produce great imaging regardless of where you place the tweeter. Like I said, imaging and soundstage information comes from the midrange frequencies. But from a staging and imaging perspective, you need to install the midrange as far away from the listening position as possible putting more effort on that rather than the tweeter placement. You want equal pathlengths, and putting them as far forward as possible makes the differences in pathlengths less.
If you're only goal is tonality (and NOT imaging), than speakers in stock locations is fine and really has no bearing. You can install speakers ALMOST anywhere and have great tonality.
If you're goal is good sound with limited imaging (and MUST use the factory speaker locations in the NSX - which will suck but there's not a whole lot of options), I'd put the mid in there with the tweeter as close as possible (mounted in the factory grill in the forward area), and aim the drivers door tweeter at the passengers left ear with the passengers side tweeter aimed at the drivers right ear to help with any left/right bias. However, using the stock door locations, I would not expect to ever achieve great imaging."
The real reason one will not achieve proper imaging with speaker baffles like this is simple. It still uses the stock speaker locations and THEY ARE NOT OPTIMAL. Not because the tweeter is placed too low...
If you really think placing the tweeter low hurts imaging, try listening to some of the cars that won their classes at IASCA World Finals. You'll mostly find kick panels with tweeters inches higher than the floor. That's about as low as you can get. And guess what, those cars all image GREAT.
