hi im just wondering peoples opinions on what they think is the

Biggest baddest, and loudest (single) subwoofer out on the market

Money is no option, so post a reply with a link ok, thanks Tom

i have seen one of those autobahns set up at a DB drag and it got molested by 18" cerwin-vega STROKER. they were both single subs, both in civics, and i think the autobahn h it around 140 and the stroker hit like 154
but then again compare price tags per inch of woofer

 

There is absolutely no practical use for this Audibahn. It's a show piece made to look at. It's performance is not all that impressive. In fact, it's absolutely horrible. In an infinite baffle design which should render the lowest system Q, it is still over 3.00. Anything over 1.00 is extremely undesireable.

It's effeciency at 88.9 dB is terribly pathetic. With a cone that size it should easily be about 100 dB with 1 watt. They don't even publish the xmax specs but I doubt they are any better than the 18" version.

There is really no use for this woofer than looks.

Two Blueprint 1803 with 2000 watts total will put this thing to shame. At least Clarions 32" sub had some redeeming qualities to it.

In conclusion, is an overpriced paperweight.

Is there a bigger sub? probably not. Is there a badder (worse) sub? There may be. Is there a bigger ripoff on the face of the planet? Maybe some Bose speakers.

 

the subs i'd like to have, but probably never will are...
audiomobile mass 12" - www.audiomobileinc.com
eclipse 88120tidvc 12" - www.eclipse-web.com
boston acoustics pro 12.5LF 12" - www.bostonacoustics.com
and in the affordable range...
avi sls300 or gx300 12" - www.avisound.bc.ca
soundstream exact 12" - www.soundstream.com
jl audio w3/4/5/6/7 12" - www.jlaudio.com

personal preference, i like the sound of twelves. the tones are cleaner and more precise. there's no real reason to jam a bunch of fifteens into anything but a concert hall. what the point of having a subs in your car if you can't sit in it to enjoy it?

 

hey dnewman

Your the idiot. its mad_rx2 not rx7

anyhow, i dont think the louder the better, or the bigger the better, i just left all those posts to see if anyone else knew of any sub bigger etc

I hate that sub myself, id never spend $7000 on it

and, im a bit of an audiophile myself and, i go for quality , not just loudness,

In my home I have a sunfire 5 channel amp and a sunfire signature subwoofer, this is only a 12' sub, but its good enough for me, and my rears and fronts are martin logan electrostatic flat panel speakers, U see, i go for quailty, not size or just bulk www.sunfire.com

 

F**k that, check out this sub...

http://www.crutchfield.com/cgi-bin/S...RFL152&o=M&a=0

It's an MTX. What you think?

MAX WATTS RMS IS 2000!! Peak is 4000 and it's only a 15" sub.

 

nice specs but i hate mtx, you cant feed them their rated RMS power otherwise they'll just blow up on you. happened to me and my friend a few times.

 

We sell , as far as subs. MTX, Alpine, Xtant, JL Audio, Sony, Pioneer,PPI and Audiobahn.. I seen 4 of those MTX-RFL's (RFL stands for Really ******* Loud, and MTX stands for motivated towards Excellence) 15's in a Caravan at the Nashville Convention Center. For the finals, and i forget the unlimited SPL total, but it was soemwhere around upper 160. Thats 4 subs people!

Its been said before and Im gonna say it again! power DOESNT BLOW speakers. Distortion blows speakers. I could take a JL W6 and put a 50 watt Pyramid amp on it and blow it up. Main reason subs are returned is a charred voice coil. That signifies distortion.

The way an amplifier produces sound to a sub, is that it produces AC voltage. Now when you clip (distort) the amplifier, it begans to send DC to the speaker. Wanna see what DC does to a coil of wire? Plug your cig. lighter in and watch it get hot.

I beleive power ratings on subs are useless. About as useless as efficiency rating on a sub at 1k Hz. Look more important factors when choosing a sub, Qts, Fs, VAS.

 

I agree and disagree with what you have said.

Heat kills speakers, not distortion. Now as far as distortion goes, there are a couple types to consider. They normal signal distortion will not effect a speakers at all. You could play a speaker with an amp providing 80% distortion and the speaker could care less.

Now, when you are talking about clipping, that is slightly different than tradional disortion. The clipped signal starts to act like DC current and during that the time the amp is clipping, it can send 2-3 times its rated power to the speakers. That is what kills speakers.

Power does matter, distortion does not (unless that distortion is clipping and even that isn;t always the case) If you send a fully clipped 50 watts to a sub that handled 500-1000 watts, it wouldn't come close to blowing that sub. But, in turn, If you have a 300w RMS sub, and send it 1000 unclipped watts, you'll alter the VCs parameters if not completely burn it up. Power ratings do matter, but it's only part of thr equation.

 

Thats like saying, if I record someone distorting an amp and sub combo. And play it back on my stereo is it still distortion? Of course not, I left a few things out in the last discussion. I didnt want to drag on for 2 weeks. And quote several formulas, and etc. When most of the technical jargon is useless. I had enough of classes that teach properties of audio waves, properties of amplifers versus distortion at various power intervals. And most of that is useless bullshit. I leave you with one question, what percentage of speaker returns are from abuse? And how many are from actual manufacturing defects?

And by the way I have a pair of MTX 12's (T3124's) rated at 100W RMS and I
have an old PPI PRO MOS 2100 , which is 100RMS X 2 into 4 ohms, but it is like 800 RMS , bridged mono to those 4 ohm subs. (2 ohm mono) Now if my math is correct, Im running 4 times there rated power... Humm no problem there... Of course I have never blown a sub in my life, but I know what music is suppose to sound like.

 

In my study I have 2 marantz 3 way spekers, they are fairly old, and i recently replaced my tweeters and mids in them

The tweeters i brought had a 200wrms system powere rating (with correct crossover) the amp I have is an old realistic sta 240, which has 4 speaker outlets. The Amp is a massive old thing, not more than 130w a channel though

anyway I have a marantz ec500 pre amp hooked through that

and i had the volume on my power amp on 1/2 and i slowly turned up the volume on the pre-amp, it was pretty loud then i heard distortion then quickly turned it down, i think it was my amp, which caused clipping, My 200w tweeters no longer were woking, and I took them apart and the voice coiles were absolutely fried, so I think i will get a cheap 400wrms piezo tweeter, that should put up with the abuse

 

I don't disagree with anything you said here, but I doubt that you are sending 800 watts to the speakers for very long periods of time. I know the amp is capable of producing 800 watts, I had the PRO MOS 50 (400 watts), but if you were sending the full 800 watts to it all the time, you would be driving it past linear excursion levels at 60 hz, in a sealed box. BTW, according to the specs I could get from MTX, your subs handle 200 watts. To play down to the 20hz range, you can not play more than 100 watts without exceeding xmax and risking damage to the driver.

BTW, I wasn't trying to argue with what you said, so much as clarify it.

 

Hey,

you lot seem to know a fair bit about audio right?

well i have a question about home audio amps, here it is

Ok, i were wondering what the difference between New Amps like sony, that claim 100wrms X 5 and there only really light

and how come the old style amps have massive capacitors(4x 18000uf) and huuuge heatsinks in them, eg NAD series 200 from the early 80's and weigh an absolute tonne

whats the difference in how they operate, how come newer amps are so light and lanky, if you know what i mean?

thanks

TOM

 

There are a couple of reasons. I'm not sure if the NAD amps you are referring to were Class A amps or not, but that could play a huge role. Class A amps can act as space heaters because of their ineffeciency, and because of this, they have a huge heat sinks and enormous power supplies.

The quality of components also can make a huge difference. Like you mentioned, you can find two equal value resistors and have one that is 3 times the size of the other.

I have a Crown PS-400 amp that is rated at 280w x 2 @ 4 ohm and it weighs 55 lbs. Their current offering with similar power weighs 35 lbs and has more power.

As far as performance goes, I know that the max amperage on a Pioneer receiver I measured was 6 amps, while a 40 watt NAD had 36 amp output. From listening tests, it seemed to make a huge difference.

 

This post just makes me want to say get a clue... Man I don't want it to seem like I am flaming, but those specs are meaningless. What are the Theile Smalls on the speaker???
Thats what will tell me how this speaker works and how bad it is.

Yeah you can mechanically build a great big woofer than a moron shouldn't be able to blow up, but how does it sound??? Titainum/aluminum? Yuck... ever hear a speaker cone ring... do you have to dynamat it like the Eclipse, just to have it not reproduce/ring over 100hz? Maybe thats why it has a 2 inch surround.

And power ratings??? Power ratings are useless... I bet I can blow that woofer up with only 100 watts sent to it. As mentioned in MIKE-P-28's reply distortion will blow that woofer just fine with minimal power. With a 1000 watt capability you should be able to plug it into the wall socket which is a almost perfect 60hz square wave... wonder how long it will last.

and how many people are gonna use a 50+ lb, 34" woofer that is 12" deep in a car???

So a Louder woofer... sure tell me the Theile/Smalls prove it, but I have a hard time thinking at 88.9dB @ 1watt/1meter that this woofer is any louder than a 12".

Bigger woofer, probably not...

badder: well there is my idea of bad...

 

@ dnewman

I wasnt trying to argue either, sorry I missed this post. I just usually state what I know in a way that seems im offended or trying to argue LOL

Hard to take tone from a person typing words LOL

But Icemark, you and a few others are VERY knowledable people.

By the way how many times you hear someone driving by and you hear the tweets just screaming for mercy and they are like that sounds good... Man Im like a 100 feet away and it sounds like my bacon frying in the skillet on a brisk morning... God im like cant you hear that distortion? Are you deaf? LOL

But yeah I know your right about not driving a speaker continiously with 800W, cause music is transient and the output changes. But if it was a steady tone, of say 30HZ hell yeah you'd toast em quick.. Just like a speaker , when playing, isnt hardly ever 4 ohm or 8 ohm or whatever. At resonance the speaker can be a high as 1K/ohm or even higher. Ive been doing this professionally for 12 years, and the day I say I know everything is the day I'd better hang up my blue point crimpers. Cuz I learn something new almost everyday!

Hats off to you guys.. Thanks for the info, we all learn from each other...

 

Yeah when I was putting in stereos for a living all I heard when that happened was the sound of money. I knew that he was gonna have his system ripped soon and would come in for more.

In CA we have company called Good Guys, it’s a big chain like Circuit, or best buy. Anyway they used to have this commercial of a guy at a street light and this gangster car pulls up just blasting, all sorts of distortion. Back in the first car the wife says," just let them be" while the driver (a clean cut type) keeps tightening his grip on the wheel.

Finally after listening to the Boom hiss at the light too long, he says," I can't stand it anymore!" jumps out of the car, gets in the other car and starts fixing the bass and treble in the gangster car by adjusting the *****.

Finally the commercial ends with the guy giving the gangster types his card the sound is much less distorted, and saying," that will help for now, but you need to come in and see me. I can help".

I was just like that. BOOM HISS = money.

 

cerwin vegas

 

Cerwin Vega Strokers have a pretty good rep so far, what kind of amp power do they need to run sufficiently?

Mtx are also nice for the money the 15" spl version mmmmm

 

k end of story is audiobahn does make the single loudest sub in the world for car audio righ now, it hits in teh 160s i think?? but newayz yeah strokers can stroke my man unit

hmmm has anyone here ever heard of the Adire Brahma subwoofer, insane videos of it on this website, including one looking at the roof of a blazer with 1 15" a must see clip, insane for 1 sub

http://www.adireaudio.com/mobile_aud...hma_series.htm

Read all the specifications and watch all the clips this is one insane sub, look how far the linear throw is thats so crazy post what you think... Has anyone heard this subwoofer before its supposed to be a great SQ woofer also... thanks

 

I used to have 4 18" Stroker D2's in a Tahoe. Box filled up the whole back of the truck, from front seats on. They are loud, however, CV is going through a buyout right now, and recone kits are as hard to come buy as an AIDS vaccine. They guy that built my stereo, competes a lot, and right he's using the MTX sub. They take a hell of a beating, and best of all, can be rebuilt. Either way, I've seen pretty much every type of woofer in action during my competing days, and the ones that get off the hardest are those that aren't easily obtainable. In all honesty, subs are just like a 7, unless everything is coherent with other parts (amps, wiring, batteries, deck, eq) and if its tuned right, she'll be bad a$$. If money is no object, don't just assume that a sub is the loudest bc it costs more than any other. Also, you can check out Planet Audio, Earthquake, Massive, and Rockford. Do some shopping, talk to those who compete, call some shops who have many different types, and no specific preference. And if you are going real loud, save some loot for a new back glass...
