I'm looking for contenders for my next system for the subwoofer. In order to get the lowest possible frequencies and highest possible efficiency, a 15" sub is likely going to be necessary in that build.
I want to the sub to run on no more than 350 watts and still deliver a decent car shaking experience. I will be getting an all-electric car, so the system will need to be a high-efficiency system that runs on the least amount of current while still delivering powerful SPL output and the best possible sound quality.
The best example of what I want, which I could find online while searching was the old-school JBL GTI-1500. It's efficiency, frequency response and enclosure size all seem to be optimal, only problem is that this is a very old subwoofer and difficult to find.
I would like help getting a list of similar contenders from others please.
