Want a Brahma but need a box too? We have the perfect solution for you – a Brahma 12″ and a 2.0 cube ported enclosure tuned to 32hz, double baffle with flush mount using 13 ply birch veneer construction. Complete with stained finish with pre-wired metal binding post.  

Enclosure dimensions – 15.50″ tall, 17″ deep, 26.50″ wide, 80lbs.

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 we were at the forefront of high excursion drivers pushing the envelope to truly linear excursion levels never seen before. Fast forward to 2019 and we have went 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.

For 2018 we started from scratch and went back to our roots on the original Brahma design which has been completely revamped from the ground up utilizing a dual stack of Y35 Grade ceramic ferrite magnets and a fully finite element analysis optimized motor structure. Now dubbed the Brahma Mark 2.5 we have successfully made the driver 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.

We’ve went back to the books on materials science and developed our own proprietary dual 8” progressive roll spider profile. We’ve tested many different blends of materials while developing our new spiders and have developed what we feel is the most durable and long life phenolic resin impregnated Nomex poly-cotton blend to date. This technology is just one small piece of the redesign puzzle which adds up to allow us to keep the Brahma Mark 2.5 as sound quality oriented as possible, without sacrificing overall SPL output.

The Brahma Mark 2.5 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 we have stuck to our roots and continued the tradition.

The 2018 Brahma Mark 2.5 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 is truly an audio enthusiasts dream and will bring out the bottom octaves in a truly unique style!
