Hmmm...well I adjusted it today to 80 Hz on the amp. It does pick up a little bit more bass - but that's not exactly what I was talking about. It sounds very strange when it hits the higher bass - not the deep bass. It sort of pings to it. When I had my audiobahns in a sealed box it hit the higher bass very well - it sounds very strange in this setup- maybe it's just me not used to a ported box? It was especially evident to me today listening to some DMX songs. Dunno, but I definately liked the other setup for higher bass.

 

what's the volume of the box and what's the tuning frequency?

 

Steve made the box of 1.5 cubic feet per chamber. Ever thought about burrowing a friends amp or sumtin? Trying it out?

Im serious that thing is capable, and your right too, you might need to get used to a ported box. I myself love ported, has better SQ to me and seems to pound deeper and a bit harder

 

The DB Drag world Champion in street 1-2 hit 155, and it was shocker subs.... a FAR cry from a 12w3.

I am not sure where you might have heard this car, but i doubt that it was a legal score.... most likely in port wars or outlaw....

 

Oh it was legal. Buddy of mine has 2 competition cars one with the 12w3s and one with 2 15w3s.
oh its loud, jl rules

 

Where's my BS flag. There's no way 2 12w3s would hit 157dB. Like rthompson said, possibly outlaw but not legal. Do you realize how loud 157dB is?

 

So, how is his car set up? I imagine he has a wall and 1000 watts per sub...

 

Yea wall for the 15w3s and 2 planet audio 2500Ds
for 12w3s were just in a huge *** box with 2 amps.
1 on each sub

 

You need to buy my carpeted sealed box and my 12" Diamond Audio M3's. I bought them from a local JL distributer and he just started selling DA. He told me to come back after I got them hooked up and needless to say he was very impressed. Said they were noticeably louder than the W3's and said they seemed to have a little better sound quality. They are 500w rms handling each. I powered them with a Orion 250r HCCA ( also for sale ) is under rated 800w x 1 RMS at 12v which means at 14.4 v it is closer to 1000w RMS,,,,, NOT PEAK,,,,peak dont mean crap.

Also JLs like power, and you comment about more power blowing them....It is harder on, and easier to F up a speaker by under powering it than over powering it. I had these 12's in my car for about 1-2 weeks and they POUNDED. Looked like they were going to fly out of their baskets, with no distortion. And sounded awesome.

 

That's interesting. Maybe I do need some more power. They hit really hard on the lower bass - I love that. So what amp's are you guys suggesting for the 12W3 4 Ohms versions then?

 

There are quite a few that would work very well. You might wait for some more input. But like I said I am selling my Orion 250R HCCA right now and it would be a perfect match, and cheaper than a new amp. It is a "Cheater" amp that is only rated at 2x50w at 4ohms. It is specificly made for competition because it will keep you in a low 0-150 class, except for you actually have about 1000w. That is why it is called a cheater amp. It is a very powerful High Current amp. Email me for more info, if you are interested. But also PPI, Older RF amps, any Orion HCCA stuff.

Just make sure you shop for an amp that will match you ohm needs and look for (rms) power. Usually if there is no mention of rms it is peak and move on.

 

So he runs in superstreet 1-2 then.... i would recommend different subs if he is running one amp on each sub, the 12w3 suffers 3 db of power compression by the time it hits 500 watts. He could easily gain a few DB's with a simple sub swap. The W3's are efficient subs, but they really loose the efficiency when you pour the juice to them. In many cases often surpassed in efficiency by less efficient subs when you give them decent power.
