I'm looking for internal plans of a JBL ASB6128V. Anyone have it?
I can't help you at all; but, maybe, you can help me with my curiosity, what is your application for this sort of sub. For HT my JBL-B380 can be way too much if not set at half gain on a 560 watt amp. That's to say, it will reproduce the most minuscule evidence of bass at levels much greater than is realistic, or where bass is presented in its proper place. You can make a box for its 15 inch 2235H Woofer for peanuts. You can buy the speaker for peanuts too.
