Re: Alpine type R 15 should I build the box to there specs ?
I've built enclosures for the 10" and 12" Type R's and made them to the specs in the manual and they pounded surprisingly loud. The ports did seem a bit too small, but they worked great. Same thing with my 12" Orion enclosure, the port is only 1.5" wide and it pounds louder than any single 12" sub I've heard. Going with the factory specs might be just as good of an idea as changing them, it might be a better option.
