I am currently interested in the adire brahma 15 inch sub. i will be getting 2. I was wondering if im choosing a very good sub for its price. does anybody have this sub? if so do u have pics or wat type amp that you used. i want these thyngs to hit. a friend of mine told me about this place and i was just wanting all the info i could get. heres the link for the specs on these things. brahma

 

they are VERY good subs......but i don't think they're available new anymore, or temporarily, im not sure......but yes they are very good subs, some say the ultimate sql sub..........

 

wat happened to them not being available?

 

I remember the Ascendent Atlas subs, which were based on the same XBL2 motor as the Brahama, are discontinued. But Adire owns the XBL2 technology. As far as I've ever been told they are still in business.

 

I hear they are the ultimate SPL and SQ speakers... ultimate all-around

I am interested in getting these down the road, but new they run like $400 a piece I think... and I'd be a bit worried about getting used competition subwoofers.

 

2 15" brahma's? Thats waay overkill IMO.. Even one of those would be sufficent.. You'd be looking at probably near $1000 just for the two subwoofers, and they need I think 1.25 cu ft of space each in a sealed box if i remember correctly..

Here's a video of one 15 in an explorer with 1500 watts, the roof starts flexing, granted the explorer itself is a box.

thats sick....I dont think I would ever want a system to shake that bad...My truck rattles to **** while Im pumping gas. That roof video is truly insane....

 

ok well now that i realize one is good enuf, how is there warranty and wat amp whould i push it with. and i thought they were still in business. thanx

 

thing is, you only need about 600 watts to drive the brahma to full excursion, if you give it the right box... they have specs on their website.... they are VERY efficient for the amount of sound output.

sweet.

 

thanx guys. um i kinda suck in the amp department. so wat companies are real good? like i can spend around up to 500 roughly for an amp.

 

cant remember how much a jl 1000/1 is but ut would do. ive heard good stuff about hifonics too. i think scrappy has a couple of those under his belt.

 

oh yeah Hifonics.

wait,

they suck.

 

lol oh yea. well if u search these forums u will find some good stuff and some crap

 

brahma wins hands down.

 

go to www.ecoustics.com and research on it. THeres tonz on the brahma. Great sub

 

im not sure why, buy i thought i read somethin on ca.com about them not being available anymore......could be wrong though, don't know why theyd quit such a great sub.

 

I could be retarded, but I couldn't find anything listed on the site

 

at the top right you'll see "forum" click that then go to car audio, then go to subwoofers. then search for brahma.

one last question guys. how do they face to kicker. or lets say jl or audiobahn. i mean im lookin on the vids at that realm of excursion place. i just want some other thouights on here. thanx

 

I'd take a brahma or RE SX, XXX, or MT over my 18" kicker cvrs any day of the week. IMO, the XBL^2 structure just looks plain amazing. It allows for clear bass all the way to max excursion from what I've heard.

Word is out RE is making yet another proto-type sub. This one is going to be a 54 mm xmax and a 1060ish OZ magnet. I'm guessing their going for something to beat their MT series line.

 

the brahma will destroy anything audiobahn except for looking cheap...........
brahma's>kicker IMO
and the brahma is in a handful of subs that supposedly compare to the jl w7 series along with the re audio xxx, ss rlp (way cheaper than anything mentioned)..........

 

brahmas are 28.5mm ONE-WAY

I assume that the ratings you give, the 54mm, is one-way as well? That is astounding, and probably impossible.

maybe it's 27mm one-way?

 

That's one way. From the small icon images I've seen leaked out of RE the magnet is longer than normal compared to the MT's current style.

There last prototype sub was suppose to be 6" pole to pole.

 

can't really compare prototype subs...only consumer-available/grade subs.

 

You can't compare a freakin brahma to a kicker i'm sorry.

 

agreed.

 

I remember the last prototype they had... it looked like a rail gun. it was for theators IB set up

 

^^^^here's a pic of the currently "unnamed" sub from re.......

i think this is the sub your talkin about with the 54mm excursion and 1060oz magnet.......




i think i got that right.........


and i wasn't comparing anything kicker to the brahma. I know the brahma is a better sub......

 

That was the last prototype. It was first dubbed "XMX" then was switched to "unnamed".

The new prototype from the looks doesn't have as flat of magnet.

 

what kind of power do these subs need? A brahma can reach full excursion with as little as 600 watts in a sealed box

 

The above subs are for mostly competition.

You can't really compare a MT taking 5k RMS to a Brahma taking 600 RMS.

As for the power, XXX --> 1600 RMS, don't put 2400 RMS to them or you'll pull the leads right off. I know of a person that has done it. The XMX and new prototype I'm not really sure.

Brahma would be an excellent daily driver sub with a lot of quality thump.

 

what kind of SPL are we talking from these XXX XMX subs? (single)

because they don't seem worth the money, since a brahma is already $400, I bet these are MUCH more expensive.

I guess if you were overly obsessesed with getting that extra 3db over the brahma...

if you were going for the biggest, baddest setup in the world, would it be better to go for a truckbed full of brahmas, or spend that same amount of money on fewer competition subs?

I think quantity over quality, to a certain extent.

 

i'd like to wall off a motor home with brahma's.......then drive it to comps......hehehe, i'd win..........

 

while we're on the subject, sort of... can somone explain the following to me?

let's say you have one sub, and you get 120db. Why do you only get a slight improvement with TWO subs? say 5db maybe is about all you get. Is there really any point in having two subwoofers? You get 5db more SPL, but do you get DOUBLE anything? Do you at least FEEL twice as much bass? After all, it is moving TWICE as much air as a single-sub system.

 

The numbers on the scale raise exponetially. Im sure jim wioll correct me in the morning on the exact numbers but an increase of 5 db is about 1.5 times louder than the previous numbers.

 

so, say I had one brahma putting out 150db, and someone else had 4 PPI 15" subs which scored 150db, which one would seem/feel 'louder'? They wouldn't be the same, would they? You would hear/feel the bass further away with the 4 woofers, right? Would the bass would have a more penetrating characteristic?

 

150 dbs is 150 dbs. The incar "feel" might be different and far as thing moving and the actual air pressure. Really it depends on alot of factors. Things like if one is ported and one is sealed can change alot. Plus what vehicles the equipment is in makes a difference.

 

so if you could put in 1 sub at hit 150db in our thirdgens, and put in 4 subs that in total score 150db as well, it will sound roughly the same?

because at that point, it seems that there's almost no point in having multiple subs because the increase from one to the other is only a few db and yet it is buku money.

I still like the look of two subs though.

 

Basically yes but the ability to be able to set up a sub to do that in a 3rg gen is hard due to airspace constraints and design of the car. In past a post I talked about nate munson who hit 169.XX with a 10" sub. Stuff like this takes alot of trial and error, tons of power, and car that is made to do this and usually only does this with a huge box tuned to one note.

A problem I see with the 2 mentioned setups, If you stuff 4 15s in the back of a 3rd gen its very unlikely that you have enough airspace for them thus not gaining anythign by having the extra subs.

 

does anyone agree wit saigon bob bout a jl 1000/1 for one brahma? is that too much power. now would a kicker 1200/1 work also. the kickers are a lil bit cheaper. that makes me a lot happier if they work. lol

 

interesting... so probably our cars would need only one brahma... two wouldn't be of any benefit..

one brahma for our car would take about 800-900 watts with the airspace we could give it, so a JL 1000 (if it REALLY put out 1000RMS watts, would be perfect.)

 

sure if you want to spend way more money than you have to, a 1000/1 will slam a brahma. you can pick up an elemental designs nine.1 amp for 300 bucks at www.edesignaudio.com
rated at 1200x1 at 1 ohm, but they're way underrated, mine put out almost 1500 watts without mods. dont think just because its cheap its not good power, like lanzar or something like that. its clean power, just as clean if not moreso than the jl. only reason its so cheap is its a smaller company rather than a huge corporation.

 

In the right box you can get a XXX to hit a high 140s fairly easy in a sedan. I've seen vids of 2 XXX's hitting 150+ in sedans. I believe the XXX retail around $435 shipped for a 15". Basically when I hear people describe them they say there about 50/50 for SPL/SQL while the brahma is 60/40 little more gear'd towards SPL.

As for the "XMX" AKA "unNamed" I heard it was going to be around MSRP of $600.

As for the JL 1000/1 I would pick it over a Kicker 1200.1 amp any day of the week. My buddy had a 1000/1 on his 12" W7 and it worked pretty nicely. He managed to hit a 147.0 in the port box from JL's plans in his celica. If you check out the specs on the amp it's supposely will not lose output until it drops below 11.0 volts. From my understanding the JL 1000/1 makes more than 1000 RMS. My old 1200.1 Kicker was suppose to produce 1480 watts RMS at it's rated output, but kicker rates the voltage pretty high compared to what you'll really see with daily driving.

 

how did you measure the kicker to ensure it was putting out 1480 rms watts?

 

No, I bought it off eBay to resell it to make some money as it was still new in the box.

But as I was saying on the test sheet they use 14.6 volts or so for the benchmark. Running 14.6 volts 100% of the time pushing a kx1200.1 in a daily driver wouldn't be very possible.

 

my brother just bought a powermaster alternator that is supposed to push out 140 amps.

the test sheet says it's designed to maintain 14.8 volts, and runs 156 amps max, and 106 or so at idle...

is that 14.8v extra-ordinary? if not, then why is it that hard to push that amp in a daily-driver?

our thirdgen alternators tend to stay around 13.5v, which I dislike about them.

also, once I get to about 20-25amps at idle in my car, (headlights and fogs on,) I see a voltage drop, which means that the alternator can't do squat at idle.

our stock alternators = suck.

my friend's ford ranger 2.3l has the stock 90amp alternator and yet he has two gigantic truck batteries mounted in his truck bed, and runs them down all the time with his subs and stuff, never had a problem.

I've killed one of our 105's by charging a dead battery(10.5v), one time, plus the alternator was only a week old. Sad.

also I believe the eD amps are rated at ~12v so if you had one of those powermasters that actually keep 14.8v, you'd get 1480 RMS watts from the nINE.1 (assuming it produces power proportionately, and the original measurements were accurate.)

Does anyone know if the powermaster alternator, (which claims 14.8 as it's voltage,) will MAINTAIN 14.8 as long as you don't exceed the 105amp idle current output? because if so, I think I might get one of those.

 

well above som1 said the xxx is for about $435 shipping and handeling. the brahma is roughly the same. i saw it for 405 without shipping. i was under the assumption that the xxx was way better than brahmas. man im gettin confused. i guess another vote is in order. wat should i choose between the two. and again can i get ahold of the xxx fairly easy. at least we got the amp area figured out.

 

Keep in mind that there will be a voltage drop when you go from the alt to the battery and then to the rear of your car. Also the only thing your alt is there to do is charge the battery not run the entire car, this is why most high end amp makers publish the RMS power @ 12.5 volts and not 14.4. In a real world, non competition car you will most likly never get 14.4 volts at your amp especially in the back of a car.
