That's not a sub....THIS is a SUB!!

[dnewma04]

This is a blueprint 1803. Arguably the best subwoofer made.

[rumblefish360]

HOLY SMOKES!!! That there be a big'ol'magnet!!!!

[dnewma04]

I forgot to post some info. The cost is 249.00, power handling is 1000 watts (been tested at well over 2x that without exceeding xmax) 3.5" point to point excursion. Dumax verified 2" of linear point to point excursion. It has more displacement than my small block in my '66 chevy (340 cu in of displacement for the sub, 327 for the chevy). It out displaces all of the SPL subs on the market.

This sub can't be beat for the money, and possibly can't be beat with any amount of money...

It is an 18" sub that weighs ~55 lbs. The sub on the right side of the pick is an Adire Audio Maelstrom which is a monster as well, but looks wimpy compared to the blueprint driver.

[98ramss/t]

that is a monster but i think the RFL has a little better spec sheet.

MTX152 15" subwoofer , 2 2ohm voice coils, 2000 rms/4000 peak, mounting depth 9.375", 55 pound magnet, 4.35" peak to peak excusion.

its about 1000 smackers retail and will be sent to you in a wooden crate along with a recone kit just incase you blwo the first one.

Couple of problems with the RFL

-hasn't been able to handle the power it is rated to handle
-sounds horrible
-only a 15. The 1803 still displaces more air
-cost 1000.00

The blueprint as as good of a SQ sub as it is an SPL sub, bench proven to handle much more than it rated handling, and costs 1/4 the total of the RFL. Give me 4 blueprints for the same price and I'll have close to 5x the displacement capabilities for the same price.

[dnewma04]

Oh and the magnet on the RFL is only 19 lbs. The CV Stroker is actually heavier than that. Then again, magnet weight is not really all that important anyway.

[QUIK 95]

You are all wrong, this is a real sub




60" sub with 5" of surround. Burped once at 12HZ, did a 161db and the truck imploded.

[dnewma04]

The link didn't work...what is it? A pic of the 34" audiobahn woofer?

nevermind, just read the rest of your post.

[78 Red Express]

i have you beat!!

Shocker audio SIgnature series octacoil 18" subwoofeer, yea thats right, 8 coils!! 24000rms with a price tag of $5000

[dnewma04]

The VC will melt with 24kW. Even the owner of Shocker said that he doesn't know where the rating came from. Somebody else came up with the figure. Besides, the Shocker moves less air than the blueprint for only $4750.00 more....

[got20s]

how bout the JL w7's?????? hows everyone think they're gonna do??? thanks

cHrIs

[dnewma04]

They are very nice subs, but the largest W7 is only 13.5". The Blueprint 1803 displaces 50% more air for 33% of the cost.

At least the JL Audios "look" cool if that is important to anyone.

[got20s]

lil more SQ out of a w7 than any 18 inch woofer though .... i don't care to have it loud if it sounds like crap lol

cHrIs

[dnewma04]

Ahh...I see you are a follower of the "large diameter subs sound like crap" misconception. This is completely untrue and in most cases just the opposite. If I were to enter an IASCA SQ event, I would not use anything less than a 15" sub under any circumstances. Small diameter woofers need to be pushed much harder to attain the same levels as a larger woofer. They also are much less effecient and in most cases can't produce as deep of bass.

In the case of the BP1803, I have absolutely no doubt in my mind that it would equal the SQ of the JL.

Granted, there are some crappy 15s and 18s, but there are as many crappy 8s, 10s and 12s.

[got20s]

i'm just going by my own personal experiences.... i've heard lots of subs in cars.... anything 15 and over are USUALLY pretty sloppy subs.... sure they're loud.... yippy... so what r u gonna do ... drive around with a bass track playing all day? i like to hear my music personallly

so the BP1803 is a better sub than the jl 13w7? i think not.... why would jl spend 6 years to design a sub that is outdone by an 18 in sound quality and spl both? hm.???? doesn't make much sense to me

just my personal experiences

[DakMatt19]

I'd rather have 2 or 3 really nice hitting 10s or 12s than 15+'s that just shake your paneling and make you deaf. For competition all these subs are obviously the $hit, but I too like to hear my music.
Just my two cents I'm sure someone will be along shortly to disagree with me.

[dnewma04]

I personally am not in the SPL dB drags. I'm a music fan. I don't try to impress everyone with my system. If you heard an 18 or 15 that sounded bad it is because they weren't installed correctly, or it was a crappy speaker.

I'll repeat what i said earlier, there is no correlation between larger diameter and bad sounding bass. Try listening to a Lambda Acoustics SAL series or TD series if you get a chance. The TD series is probably the best woofer for SQ made at any price. With an underhung motor and a faraday ring and a copper phase plug on the Lambda, the JL wouldn't stand a chance of being in the same league.

Don't get me wrong, I have like every JL product I have owned (3-10W6, 1 12W4, 2 10W1, 1 12W1 and 1 15w1. They have all been top notch speakers, but there are speakers that absolutely will have better sound quality. Most of them have been around for a couple of years. Another good example would the Stryke HE15. It even has a more advanced motor than the JL, has a larger cone area and equal Xmax. Guess which one is going to be louder? The stryke. SQ? Probably the stryke again. I guess I'm just trying to save everyone a little dough by recommending some options so people don't buy subs based on looks and instead buy based on performance.

If you are truly into music, get the Lambdas i mentioned earlier, there is not a sub that can hang with them. They have 10,12, and 15s available since you like those better.

BTW, the JL W7s were designed with SPL in mind and the people I have talked to who have heard them said that the SQ of the W6 was slightly better, but the W7s were much louder.

[dnewma04]

I can't disagree with your opinion Dak, I'm just trying to clear up the misconception that 15s or 18s can't sound good and just sound sloppy.

The 10s you have heard were probably better quality than the 15s you heard and disliked.

I think one issue that occurs is that larger diameter speakers can play lower than smaller speakers and are much more effecient, without proper EQing and installation, they can be a bit overpowering. This is where proper integration becomes important.

I had a pair of JL15W3's in my truck in 4 cube box, 2 cubes a side running off a earthquake 200dhc(about 1500 watt) and dizzam these subs pounded hard and sound sweet. but since i have gotten my 12w3's they sound even better but the spl is lost a bit..i dont suppose those lamdas could handle 800rms a piece and come in a d6 configuration..

anyways who makes that blueprint sub, im a competitor to db drags and i have never heard or ever seen one of these before, nor have i ever seen anyone use them..big subs in the spl market right now are strokers, inhumans, concept pt's, juggernauts, shockers, resonant engineering hc, rockford power hx2, jlw3's(screw the w7's), dd 9500 series, etc...

[desktopsilver]

i havent evean heard an uttering,or mubbling of PRECISION POWER,wow this is a new era,back in the day half the people would have mentioned them,,take this as a mile stone,,are they evean in buissiness still..

[dnewma04]

You are severely limiting any chance of winning with a W3 sub. With only 15-16 mm of excursion ( i think that may be high) they just can't compete with some of the other brands you mentioned nor could they handle the power.

Have your heard of Adire Audio's Shiva or Tempest? The Lambda Subs are available in DVC 2ohms/2ohms or 8 ohm SVC. They handle 500 RMS/1000 music. The power rating on the TD15 I don't recall off hand. So, no they don't come in a DVC 6ohm config and are not really made for SPL, but they do have the ability to move some air with about the same excursion as the JLW3s. SQ is what they were designed for, so like the W3s, I wouldn't expect to win any SPL competitions unless you want to use a bunch of them.

Check out caraudioforums.com and you'll see that a lot of the guys are starting to use Blueprints. They are made by Blueprint and have only been around a few months. I can guarentee you will see and hear of them. They use a lot of the same components as the Res Eng subs you mentioned.

PPI has made some very nice subs but they never really stood as the best. They are still in business but are now owned by ADST which is a/d/s/ parent company. Still make some of the best amps avialable.

[desktopsilver]

so what is the happening with ppi,are they still right next to ,extant/mtx,what other compinies are in that little 2 block area in phoenix we here about,i had a ppi system before but my base amps were always goin into the shop,i wasent verry impressed with there build quality,,evean now i know severeal people with the same thing going on (there base amps in shop)i realy liked there upper mid ,high sonics though real clean,,they make some powerful base amps now ,,I personaly have a set of jl 500/1 and 300/4 and am very comfident when i crank on it,,they also sound very clear going into my dynaudios 3-ways,through my nakimichi mb-100,my jl 12 w3's get a rating of 7.5 on a 10 point scale,(sealed enclosure),i love my intelleguard 9000 it has great features,

[78 Red Express]

Dnewma04, 5 15W3's did 171.2(db drag legal), id say that is pretty dam impressive!!

Oh BTW, ADS had been bought out again, this time by DEI!

[dnewma04]

How many 15W3s did it take to reach that 171 mark?

In SPL comps, Vd is what counts and the W3s just can't hang unless there are multiple subs. Even then, if you use multiple subs from other companies, you can still outdisplace them. Can you tell me what competition the W3s did that at?

When was ADST purchased by DEI?

[78 Red Express]

i think it was Db Drag finals in 99, i think it was a yellow compact car(can remeber it was a sprint or something)with 5 D2's, it was all over jl's adds so you could probabloy dig it up somewhere..

DEI just bought ADST out, DEI makes awesome amps too but shitty subs IMO!!

[got20s]

definitley awesome amps !!

[dnewma04]

DEI actually did make some very accurate subs about 2 years ago, but I would probably agree that their quality has dropped a bit.

[QUIK 95]

I finally got a pic of the biggest sub ever that will work:

[desktopsilver]

iv'e seen that on termpro,i forgot the story though

[dnewma04]

That is too funny! Good find!
