12'' Adire Brahma MK II

[InhumanAcura]

1600 rms was a thermal rating actual is 500-750 if i recall

Youre incorrect. It had an RMS rating of 1600w.

I think you have the "Brahma" and the "Shiva" mixed up.

i think you're all wrong,..

If this was a mark 1 I would be all over it. GLWS OP, this is an amazing woofer.

Thanks. If this were a 10" I dont think id ever get rid of it.

There is some good reading on this topic I just found over at "car sound and performance"

search that query?,....

link?

I have my Brahma on 1000 watts in 2.25 cubes. It doesn't want any more than that power in that box.

Looks like an old skool re xxx clone. Do they share the same motor?

not a clone...they use the same motor.....these things are just as good as the XXX

Brahma Power Handling 1

Brahma Power Handling
There's a common misconception that a power rating is a power requirement; in fact, the two are completely different things! Brahma is rated at 1600W RMS per IEC268-5 (a specific test signal). Does this mean you need 1600W to get full performance from your Brahma? NO! What it means that your Brahma can handle 1600W of power with the test signal (akin to typical musical spectral content).

Below are some tables that show what amount of power is required to push a Brahma (10", 12", or 15") to full excursion in a sealed box. The tables break down a typical box alignment and show you the amount of power you need to reach full excursion below 30 Hz:


Brahma 10
Qtc-Size (liters)-Size (ft3)-Power Handling
0.5-24.7-0.87-700W
0.577-14-0.49-1000W
0.707-7.5-0.27-2000W
0.8-5.4-0.19-3000W
0.9-4.0-0.14-5000W
1.0-3.1-0.11-7000W

Brahma 12
Qtc-Size (liters)-Size (ft3)-Power Handling
0.5-170.5-6.01-400W
0.577-59.8-2.10-500W
0.707-25.9-0.92-900W
0.8-17.6-0.62-1300W
0.9-12.6-0.45-2000W
1.0-9.6-0.34-2800W

Brahma 15
Qtc-Size (liters)-Size (ft3)-Power Handling
0.5-862.7-30.48-400W
0.577-204.5-7.26-500W
0.707-80.6-2.85-800W
0.8-53.4-1.89-1200W
0.9-37.9-1.34-1800W
1.0-28.6-1.01-2500W
italicized numbers are above thermal ratings and are NOT recommended!

One thing to note is that in most cases, you need less than 1000W of power to push a Brahma to its limits. Going beyond the power listed won't gain you more SPL - what it will do is simply slam the suspension,and cook the driver (because cooling relies heavily on cone motion, if power is increased and cone motion is not there can be cooling reduction). So, if you're looking to power a Brahma, take a look at the above sealed box sizes, and choose amplification accordingly!

[Brahmaextreme]

Can you push up on cone so we can see the coil?
Clearly you have been putting rated power on the coil and that's not what the sub suspension can handle.

hey brudder,.. knew it was only a matter of time before you showed up, lol

[InhumanAcura]

Negative, negative and negative. The brahma extreme used the same motor as the xxx..later the tumult. The Brahma used a similar motor to the HC.

They were rated at 1600...

I should be able to get a picture or two of the VC's tomorrow. I had my mine on a kx 1200.1, I never once smelt VC's nor did it ever sound like it was bottoming out. I also forgot to add. I did a 142.8 on music, during a midwest SPL show. I wasnt going to participate but figured id see what I can do. Anyone can call me out, but I do remember Adire rated these things at 1600w. I was going back and forth between this and the XXX and went with the XXX. Clearly I must have made the better choice. Maybe thats why Adire went under? For over rating their woofers. If I can achieve the same SPL with a smaller amp I may just hang on to this subwoofer.
