As I was working tonight I started to think about the advances car audio has seen in the past couple of decades. It amazes me to think that amps and the technology in amps have come so far, but it seems to me that subs have very little that could be improved upon. As the years go by and amps produce more and more power it seems subs just get bigger motors and bulkier voice coils to handle the increased power. Am I missing something? Is it just working from a larger motor and trying to design around it? Are there truly no innovative ideas out there because there is nothing to improve on as far as the tech involved because of a loudspeakers simplicity or are the innovations so subtle that I have failed to notice them?
btw I have a good amount of respect for EE's for advancing the car audio culture in the ways they have. I had to take an electronics course for my physics BS and that was the most tedious, painful class I took and we didn't even scratch the surface.
