The 2021 Brahma X Mk2, previously known as the Brahma Extreme has a rich history of setting records many years ago in various car audio SPL competitions. We decided to set out and redesign the Brahma Extreme further refining the original XBL^2 motor designs and bring them up to what we feel makes the ultimate musical daily driving subwoofer!

For 2021 we set out to give a nod to the legendary aspects of the original Brahma Extreme and update it to what we feel is an excellent ode to the rich history of an extremely rugged ground pounding daily driving ultra musical subwoofer. The Brahma Extreme Mk2 also includes inductance rings inside of the Y35 ferrite magnetic gap to help lower the overall inductance of the woofer and enhance a more vibrant and tonally balanced output through out the entire range of linear excursion. It also features a high temperature 3” flat wound copper voice coil rated at 1500 watts RMS as well as our proprietary dual 8” progressive roll spider profile.

We’ve tested many different blends of materials over the past 2 years and have settled on a 100% Nomex weave for long term durability. This technology is just one small piece of the redesign puzzle which adds up to allow us to keep the Brahma Extreme Mk2 as sound quality oriented as possible, without sacrificing any SPL output for those who really like to go to the Extreme!

Featuring 4awg push pin terminals we’ve also utilized a non pressed kraft pulp hybrid fiber blend cone body and a multi-layer foam surround that keeps the Brahma Extreme durable for your sonic enjoyment for many years to come. Our standard injection molded ABS plastic dustcaps keep the cone body rigid for the Extreme applications they may be used in. We also have carbon fiber dustcaps as an available option if you would like to further enhance the overall rigidity of the already rugged Brahma Extreme.

With excellent sound quality and extreme output the Brahma Extreme Mk2 is the epitome of what an Extreme daily driving subwoofer should be!
