Free Sub!!! Jl10w3

**dXsquared** · 07-30-2003, 07:11 PM

i just got a free JL AUDIO 10W3 D2

it has dual 2 ohm voice coils and its pretty sweet... i was just wondering if 87DXHatch could tell me a box that i could make to get the loudest bass out of it.. im gonna be giving it 100 watts RMS to each coil... what shall i do? right now i built a .9 cube sealed box for it and its ok.. but i was wonderin if i made a 1.5 with a port, what would this do? and what size port??

thanks

Travis

Could you give me the model number like exactly? Is it a v1, v2... what year is it. Give me this stuff and I could do some modeling and get back to you.

Oh yeah, and what ratio SPL to SQ do you want? 70/30? 50/50? Thanks.

And may I ask why you didn't crop that picture of the car in your sig... there's soooo much unnecessary white space there

**dXsquared** · 07-30-2003, 08:06 PM

its an old ass one.. its not a V2.. and i want all bass.. the shit that hits hard! like 80SPL/20 SQ i have a 3/4 inch 4X8, and an empty hatch.. lol... lemme know what i have to do

Travis

and ill fix the sig

Can you do that? I always assumed that you had to hook up each coil in either series or parallel to one output not each coil to a seperate output. I've never seen any daigram that came with speakers with dual voice coils that indicated hooking it up to two seperate outputs.

**dXsquared** · 07-30-2003, 08:17 PM

you can do it, but its best if its a mono signal to each coil... im actually just gonna run it at 4 ohms... it will get 200 watts RMS overall

Can you bridge your amp? Most amps offer more power when you bridge them and then you'd be running off of one channel.

**dXsquared** · 07-30-2003, 08:25 PM

its 75X2 at 4 ohms
100X2 at 2 ohms
200X1 at 4 ohms

thats all RMS... i think it should be higher but i dunno.. its a wal mart JENSEN amp...

**HostileJava** · 07-30-2003, 08:29 PM

I take it it's not stable at 2 ohms bridged then, let alone 1 ohm?

**dXsquared** · 07-30-2003, 08:32 PM

hell no... its ghetto.. thats why im not gonna run it at 1 ohm mono
if it could run 1 ohm, it would make too much power for this sub.. its like 250 watts RMS

Happy b day 87DXHATCH, haha

**87DXHatch** · 07-30-2003, 08:56 PM

alright DXHATCH, I'll see what I can figure out... be back in a bit.

**87DXHatch** · 07-30-2003, 09:03 PM

Aight, if you want this thing to destroy...

Build a 3.2 cubic foot gross box. Get a 6" diameter piece of PVC pipe and cut it about 10" long, for a port. Put that port in that box, add the 10w3, and 200 watts, and you should have some serious bump.

**87DXHatch** · 07-30-2003, 09:05 PM

That'll make it ported to a little less than 40 hz, with a nice amount of port area... it'll be ridiculously loud, yet still retain a decent amount of SQ.

Any questions feel free to ask... and thanks for noticing it was my birfday, A Dawg Jr

**TJ89Accord** · 07-30-2003, 09:54 PM

I have 2 12" JL w3 v2s. They hit nice. I have my amp gains up only like half way and my radio is set for -4 for the subs and its SOOO loud. Those are nice subs. I have a Zapco AG350 amp. Much nicer than the Jenson

. But I still can run it to 2 ohm mono

. But I can run each sub at 2 ohm in stereo if I wanted... I have it a 4 ohm mono now though. sorry if this is confusing, but I have been drinking lol...

Zapco! X-P!

Nice choice of equipment.

**TJ89Accord** · 07-30-2003, 11:15 PM

yah i love the amp... blows away so many that i have heard

**87DXHatch** · 07-30-2003, 11:49 PM

I could have had a 1000 watt Zapco reference series amp for like $300 last winter, but it was right before Christmas and I had to buy presents... made me so sad.

**dXsquared** · 07-31-2003, 06:17 AM

i want to build a rectangle port... how should a make it? 6X6X10?

Travis

**dXsquared** · 07-31-2003, 09:11 AM

im about to build this box.. in like 30 minutes.. if anyone knows how big the port should be if its a rectangle, lemme know... i need an answer ASAP

Travis

**HostileJava** · 07-31-2003, 09:19 AM

I would go with maybe 2x8x10. Not sure though.

**PogiLXI** · 07-31-2003, 01:10 PM

Make Sure you put the port on the Same Face as the Speeker.

**87DXHatch** · 07-31-2003, 02:34 PM

15" X 2" by 10"
5" X 6" by 10"
30" X 1" by 10" <--- not recommended

All of those should give you a similar tune. If you wanted, make the port a little longer for a little better SQ and a little less SPL.

Also, because it's tuned around 40hz, be VERY careful playing test tones and bass mechanic material at full volume, unless you have a sub sonic filter.

Good luck

Hey dave, since you seem to be the pro at subs and sub boxes, i have a question to ask you. I have 2 Sony Xplodes (not the greatest choice, but its what i got). 12's about 1 year old. If i want to put them in a box, what would be the ideal box? I'm gonna go for probably 50/50 sq/spl. Prolly gonna run about 300w to them maybe more depending on what amp i get.

Sealed or ported? Right now i have them in a band pass, but it sucks a whole lotta MAJOR ass.

Also, what do you think about tubes? I can pick up a tube (for one sub) for like 60 bucks.

**dXsquared** · 07-31-2003, 03:56 PM

hmm... i made the box 3.2 cubes, and a 4 inch 13 inch long port.. its sooo quiet.. should i shorten the port? i am about to cut the box in half to see if it will go louder... the box is 36 long, 12 high and 16 deep (internally)... ill go shorten the port, i dunno if it will work.. i couldnt find 6 inch so 4 is what i bought
