American Bass Patriot Series Limited 250 Edition 12" Subwoofer

1776 – 2026 · 250 Years of Freedom The Patriot Series Limited 250 Edition is American Bass Audio's most exclusive subwoofer ever made. Only 250 units exist — each individually hand-numbered from the original run. When they're gone, this chapter closes permanently. The front cone features a stealth blackout American flag etched into the cone face. Flip it over and a full-color, high-gloss American flag wraps the entire cast alloy basket — stars, stripes, and soul. A machined gold pole plate finishes the build the way it deserves: bold, permanent, and unmistakably American Bass.
