wat up, i live in brazil and my mom is visting the US and i want her to bring me a subwoofer i need one sub that can hit about 155 db's (i know it dependes alot on the box 2 so if you have info on a box design that helps too) that costs about $250 at most, i was looken at some audiobahns the immortal, 2000wrms, but yall diss it so much that im changing my mind, i need a debendable sub that wont break, cuz i wont b able to send it to the US to fix under the warranty cuz i live in brazil and it wouldnt b cost worthy, some one help me out cuz she is coming back in about 2 weeks.... thanks alot lata

are u kidding me there isnt a sub out there that costs 250 and is capable of 250
nope, unfortunately not, the US has a wider range of produts then here... i use to live in the US but then i moved down here, trust me, thats y i needa get one there, so i can win freaken competitions here..... wat do u recomend?
your prolly not gonna find a sub for $250 that will do 155db!
your gonna have to fork out a lot more cash than that!
if you want one sub that is capable of over 150db, then look at Adire Brahma's (15's or Extremes), RE X.X.X.'s (15's or 18's), RE MT's, or maybe JL 13W7's.
the RE MT's would prolly be your best bet...they are strictly SPL subs though! i'm not sure on the price, but its WAY more than you are thinkin bout spendin...(anyone know what the MT's are selling for???) also i think RE would ship you an MT....but not sure though...
hmmm, alright thats cool, yea i pretty much new in the back of my head i wouldnt b able to find one for 250 haha, but that the price of the audiobahn immortal that i might get.... im not sure though im fvcking scared of geting the shyt and it breaken here, hoe many db do you think that immortal gets? i was trying to find those sub you mentioned on ebay, couldnt find them though.... do you know a site like ebay that would have them?
go to reaudio.com, you'll have to email the staff to get a price. (they ship direct)
i my opinion, anything audiobahn is a gamble! audiobahn is known for driver failure! and its takes way too much power to get them moving.
there was a post on this board a while back where a guy that owned an audio shop took a poll of how many audiobahn subs were returned to his shop...i think it turned out to be something like 70% of the subs he sold were returned!

Many shops around here refuse to sell audiobahn.
They had way too many returns and got tired of dealing w/ the audiobahn sales policy.
no, you wont find the mt on ebay or any other site but their site. for the budget your proposing, you wont be hitting 150dbs without paying a little more money. the sq of immortal will not be that good and it is not 100% reliable. to hit those numbers with that sub or any others, your gonna need about 2k watts and a ported box. the cheapest way i think your gonna get close to breaking 150db with and still have decent sq, is the re sx 15($269) or 18($289), and a good 1200-2000 watt amp($350+), and ported box tuned pretty high. marshall's list too. your gonna have some more for that.
ok, well i had actually checked out that msg b4 about the 70% return on the audiobahn subs, thats one of the reasons y i decided to come on here and get some opinions, so for me right now audiobahn is pretty much outta the question, the amps im not realy worried about bcuz here we got some good brazilian brands for amp its just sub i realy gotta worry about.... so lets say i had 400 dollars to spend wat one sub should i buy to hit 155db (cuz in reality i had 400 to spend but i had my eyes set on some dvd players, so ill put that shyt aside and just focus on the sub), thanks for the feed back
with an RE SX 18" you may come come close to 150dB...(i'm not sure bout it though, dont know bout its potential....anyone think it can know???)
RE X.X.X. 15's and 18's are known to break 150dB in SUV's, in ported boxes. that i am sure of.
remember this though...the install is a MAJOR part of how it will sound! you could have a great sub in a crap box and it will sound like crap.
one other thing...they arent known for SQ and its harder to build one right, but you may wanna look into 6th order band pass boxes...i know a guy that hit 147.1dB @57hz w/ one brahma 10 in one...you would have to play around w/ designs to get it right but bandpass boxes offer ALOT of gain. (use a program like WinISD to design a box)
yea i was talken to a guy in the back in the day topic, he said i probs will hit 145 wit a RE X.X.X 12 inch.... im thinken thats wat i might have to go with, but when i get it im gonna have to hit u guys back up to get some designs and info on a box...
d4mn i was thinking here, i am so scr3wed ima gonna str8 up spend big bucks on this after all, not much of a choice if i wanna have something worth my time and my hearing loss... huaha
is the RE X.X.X 2 and 4 ohm operation? how many voice coils? do u think i could run it at more than 1600wrms? say like 2000wrms and just not crank it to the fullest or just lower the volume on da amp?
that 1600wrms is just a thermal rating, it would only need about 900wrms to reach xmax, but you could burp it higher...this puts huge stress on the sub and risks blowing it though!
if your panning to use it for both every day and for comps, i would suggest wiring each VC to its own wire termial...that way you can change the VC configuration from parrallel to series easily, you could run the sub in series for every day at 4 ohms, and run it in parrallel at 1 ohm for comps.
you could do the interchangable port idea to get even more SPL in comps.
SPL competitors pride themselves on one tuning frequency. At tuning, the subwoofer is actually at the least excursion, meaning that's where the most mechanical control is, and it still has more output(a function of physics, the resonance of the air actually controls the cone, putting pressure on the box, but the air moves and creates SPL as well as the sub). This means you can add huge amounts of power for a burp and get the sub to full excursion at tuning, meaning HUGE SPL gains. And since it's a burp, it doesn't have a lot of time to overheat the voice coils. For everyday driving though, anywhere other than tuning with that much power applied will destroy the sub.
the 10" brahma in the 6th order bandpass that hit 147.1 dB that i was talking about was burped w/ 2300watts @57hz.
by the jonathan, what kinda power you think a brahma 10" is capable of handling w/ a burp? i'm thinking bout retuning my box to somewhere around 45-55hz and going to a comp.
With a high tune and the right box, it may be able to handle 3000W temporarily, but it's totally dependant on the box and too hard to calculate, so I can't really give you an accurate figure. Scottie Johnson puts 10,000 on each of his Brahma Extremes. If that 2300 got it to full mechanical excursion or close to it, then you won't do any better by kicking up the power by a lot. Watch the surround if possible, if it stretches close to it's limits, then you have the right amt. of power.
i use to live in the US but then i moved down here, trust me, thats y i needa get one there, so i can win freaken competitions here..... wat do u recomend?
