The ultimate solution for ultra high excursion, linearity and low distortion


The Adire Audio Brahma has always been known as a legendary driver in the audio industry since the very inception of the namesake in 2002. At that point in time, Adire Audio were at the forefront of high excursion drivers pushing the envelope to truly linear excursion levels never seen before. Fast forward to 2019 and they have gone back to the drawing board - updating the designs to surpass current industry standards while utilizing Patented XBL^2 motor technology to carry on the legendary namesake of the Adire Audio Brahma.

In 2021, upgrades were added to the popular Mark 2.5 Brahma design which include a new basket with custom tooled spider adapter for better fit and clearances, carbon fiber dust cap and a 100% Nomex spider for better long-term durability. These upgrades are on top of the completely revamped from-the-ground-up design implemented in 2018 which include utilizing a dual stack of Y35 Grade ceramic ferrite magnets and a fully finite element analysis optimized motor structure. Dubbed the Brahma Mark 2.5 Rev A, the driver has been made more compact than the original Brahma for the end user who may be concerned about mounting depth constraints, all the while improving the original legendary performance of the very first Brahma.


Unable to find a spider they were happy with, Adire developed their own proprietary dual 8” progressive roll spider profile. After more than 2 years of material testing, they 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 Adire to keep the Brahma Mark 2.5 Rev A as sound quality oriented as possible, without sacrificing overall SPL output.

The Brahma Mark 2.5 Rev A carries on the world-class sound quality and tonal balance of the original Brahma while still being able to pump out insane SPL output. Doing all of the above in such a clean fashion can only be achieved using XBL^2 motor technology which is why Adire has not swayed from tradition.

The Brahma Mark 2.5 Rev A is rated at 1000 watts RMS power handling and features a 3” diameter copper voice coil available in Dual 2 or Dual 4 ohm that will keep you enjoying your music at all levels of excursion and output for many years to come.   

The Brahma Mark 2.5 Rev A is an audio enthusiasts dream and will bring out the bottom octaves in a truly unique style!
