Extremely Strong Cone More than honest power rating when vented(1000WRMS) Makes insane sound at low frequencies with a very small box. Motor, and assembly is damn tight and well made.

I just wish they offered it in dual 4 and dual 2ohm configurations.

I earlier left a review saying that this sub was a power hungry monster and that it wasn't really all the hard hitting with even it's rated maximum power. I'd have to correct myself. I've done a lot of experimenting with it, and learned a lot more about box building(vent tuning was easy, but for the longest time I didn't understand nuetralizing air speeds). Since then I've grown to absolutely love this sub. It is still housed in it's original 1.6 cuft. net box but with 31HZ tuning from 10SQ inches of port(11inch of portdepth) on the face of the cube shaped box. Before tuning it peak at an unacceptable 35HZ when sealed but after tuning it was more like 40HZ with a wider extended powerband. The differences between 1.6sealed and 1.6w/31HZtuning is amazing. Sealed it only started to become "loud" at around 45HZ, and when it finnally peaked at 35HZ it was merely good for a 12. I carried a note down to 25HZ and then signed off and still did "OK". Vented, the sub actually does it justice. It starts getting loud at around 55HZ and becomes amazing right around 45HZ. It sounds equally loud from 45HZ down to almost 30HZ and is the definition of clean bass. It signs off at the same level it used to but I believe even at 20HZ it is louder because of how much louder it was up high and then the volume drops just as much when it starts to sign off. The sub still peaks a bit low but tuning it higher isn't accessible without increasing the airspeed and lowing SPL with my current port setup. The box is still too large at 1.6cuft. to be vented to only 31HZ. More ideally would be 1.2cuft(I know that seems damn small for a 12 but these subs are insanely space effecient) with about 30HZ tuning to make it peak just shy of 50HZ, and sacrifice the extreme low for a lot of extra SPL in a more usable region that is played in normal day to day music. The bigger box I have now punches amazingly accurate and would be less accurate in the 1.2cuft. box I plan on building but I expect it to still do excellent. The sub is mounted right now in a 1991 Nissan 240SX fastback facing the rear in it's 16X16X16 cube just 8 inches from the back wall. It will meter an honest 142-144 on a new termlab meter with 1270WRMS(the amp makes 1270@2ohms and it'd be my best estimate to say the sub is getting at least 1100W when I run it at 3ohm parrallel) at right around 40HZ. The sub will get hot and eventually burn up at this wattage if left WIDEOPEN(meaning non stop signal tones, about 1min of wide open signal makes the sub start to warm up on the rear and starts barely giving off that burning odor) but with my experience it would take a very very bass heavy song and a long period of running to burn up on regular music. I expect the single sub should reach SPL numbers in excess of 146DB(more like 150dB on the year or more ago meters) with the new box w/ 1270WRMS, I'll try to keep everyone posted. I just purchesed a audiobahn ALUM15X also and will review any differences between these subs in the near future.

With 1000 watts RMS each thats enough strength.

Not many. But Audiobahn subs will blow kindof easily if you dont break them in.

My friend just got 3 of these subs and built a triple slot ported box designed to the maximum SPL standards and they beat like no tomorrow. He has a Visonik V900HC amp pushing them at 3200 RMS. They hit so har that his CD player constantly skips. The quality was unimaginable. No distortion whatsoever. With 2 two farad caps he still doesn't have enough power. THese are some MEAN subs. Just make sure you break them in for a few weeks.

awesome bass quality and durability as well as extremely slick look to them.

peoples inexperience and ignorance to not enough power

these speakers are in my opinion better than anything ive heard. most people have a problem with them becuse they underpower them. U MUST PUT ATLEAST 700 WATTS RMS TO THEM OR THEY WILL BLOW. im runnning 2 with a 1500 rms hyphonics amp, which is actually pushing more.

low bass, never distorts, impreses everyone who listens to stereo. teaches people that there are better woofers out there, great looking woofer

demands a lot of power compared to many great woofers out there.

This woofer demands POWER and u must give it what it needs. extremtly impresive bass if powered right. if u dont want to spend money on a amp get the jbl bp1200, and power this woofer. i use a rf 750x and i love it. it is too much bass for me though

my 2 12" comp vr kicker couldn't play like this subs play, for real,$ 300 a pair i think is good deal for the power.

buy a high current amp, more than a thousand or it won't play !!!

this subs are very beautiful, when you build the box you got lost, should i show the front or the back, talking about sound they're very loud even with low volume,i mean very sensible, i've got a BD1000w rockford fosgate and its working in 1.5ohm very well in a 1.0 cf box, don't forget a 20% fiberglass to improve they very deep bass !!!

It reminds me of Cable internet how quick it is Man.

Chris Phillips got a little mule.

These subs are LOUD i dont care what anybody says if you give these subs the power they need you wont be disappointed. They have awsome sound quality too. I have 600 watts going to each run off a JBL BP1200.1 with a 1 farad Lightning audio at a 1.5 ohm load. Ive hit 148 db coming through i little hole in my back seat of my car. These subs hit low bass very well but bia bia sounds like a monkey slapping a chinese gong with its mule after consuming enlargement pills. Songs that are really deep may get these subs to move 2.5 to 3 inches easily. The bass from these subs will pound your head because its so low. But if you like high bass your better off buying a midget with a deep voice to install in your car. Give these subs 500-800 watts RMS and they will amaze you with there quickness and accuracy. Youll have to feed the midget though. The JBL is a really good amp for a good price. PB&J is good food for your midget.

Kicker Comps good for money Alpine Type R's very very good subs and pretty loud. Kickers could have been better if chris phillips had a bigger mule.

As I have mentioned, excellent sound quality. And you can purchase them for pretty cheap off ebay.Very good bass response and power handling in small boxes.I'd recommend a 1.00-1.25 cf box for the best blend of sq and spl.I heard that they preform pretty good in ported boxes too but I dont know the correct parameters.

They do need alot of power to really get the most out of them.I've heard similar subs that can get just as loud if not louder and use half the power.Very pretty....could get stolen if your not careful.

I'm not sure what the guy below did but I can assure you that he did something wrong.I powered both of my Alum's with a jbl 1200.1 and they took the power fine.I loved them.They can deliver exactly what they advertise: Clear, precise bass that keeps up with any type of music you listen too and they can deliver ear-splitting bass when you really get on them. Virtually no distortion at high spl levels. They also add a great wow factor to any system with their shiny cone and chromed out basket.I even ran one sub off my jbl for half a year when I let a friend borrow one sub and he had a wreck and the sub got busted.It ran fine off the amp and never became hot no matter how hard I pushed it.Definitely a winner if you're looking for a pure sound quality sub that can also get very loud for a great price.If you have a question about the sub email me at gsatterfield@email.com and I'll try and help out.Remember...it's not necessarily the equipment that you have that determines how your system sounds.It's the time that you put in to doing a good install.

Hmmm...they are sort of in a category by themselves.I'd compare their sound quality to L7's, also,I know a guy that has the older JL W6's and mine sounded almost the same as his and mine got alot loud

sq/ spl mix

completely overrated power handling.

good bass that will make your ears bleed but they can't handle power for sh1t. i blew them with 600 watts each from a jbl 1200.1 they ran fine off of my audiobahn a18001d but that wasn't really putting out 1500 watts either.

none similiar these all held up to their power rating.crossfire db and p1, soundstream spl, jl w3, rf xlc,

Extreme density... It's dense enough to produce tones around 30 and 40hz OK where most 12s just don't cut it. Your average 15 will do the same or better although. I've had no problems with the Alum12 as far as burning up or wearing out any of the connections or internals. It's pretty solid.

Wouldn't even turn on if had an amp with less than 25 amp worth of fuses. I recommend two 50 amp fused amplifier(Honest ones... anyone can swap a huge fuse into a weak amp) to make it respond and do something worth showing off. Anything less and you'll be put down by some dude with a pair of Lanzar 10s with an amp just like yours. A rating of 82 SPL makes this speaker not worth it.

I wouldn't listen to what people are saying about the Alum12 being so amazingly hard hitting. It is the single most power hungry woofer I have ever owned or tested. Unless you got an amp that pulls at LEAST 100 AMPS of juice from your battery you'll never touch the threshold of this speakers ability. That said when you do hit the limits it's only what I'd call "an excellent 12". As a matter of fact the audiobahn Alum12 in a 2.5 Cu. Ft. sealed enclosure (1 inch MDF w/ supports) can't create the sound pressure or the low pressence of one of my Pyramid 1200 Watt super blue 15s in their 5/8 inch MDF 3.0 Cu. Ft. enclosures. The difference is more than audible in a small/large home room or any car I've tested it in. Basically it's a high excurion 12 with great sound that demands waaaayyy too many watts for it's output. But the potential is there if you got amps growing out your ass. Another thing. I've ported the 2.5 box using WinISD beta and found that mildly porting nor extreme porting did anything but drag the speaker down. Maybe a larger ported enclosure would show good results.
