12" + 10" or.. DVC?

[xav3x]

still a newbie.. but is it good to get a 12" and a 10" working 2gether or Dual Voice Coil?

i'm guessing DVC rite?

[zcs626]

dvc is just how the subwoofer is built.....they make a DVC 10.....12......whatever size.

Just out of curiosity, why would you want a 12" plus a 10"?
You'd have a hell of a time finding a prefab box to fit a setup like that :)
Seriously tho, If you were going to get one sub , or a pair, DVC's would be the way to go because they offer you alot more wiring options and impendance/amp options than a svc sub would.
just makes things alot easier when youre mixing/matching stuff together :)

Quite honestly, it wouldn't make any sense for you to get a 10 and a 12 for your celi. The 12 is going to give much lower base than the 10 which would drown it out. You would be better off getting two 12s. I would recommend some DVC, I think those perform better than the single coils. With more ways to wire, it wont be hard to find an amp with the proper ohmage for your sub

I doubt the 12" would go dramatically lower in freq. than the 10" would, that all really depends on the design and construction of the box. If it were me, I'd go for the two tens in a sealed box (for the volume of the box, check out the manual that came with the subs, or contact the company). They'll give you a little tighter response than the 12's and, in a good box, should go just as deep.
But if you want a high power system or think you may be swiching out the amp that is driving the sub, go with a dual voice coil. Just be sure that if you wire your coils in parallel - your amp must be stable at least to 2 ohms.....preferably 1 ohm. If the specs dont say its stable under low impedance drive, dont try it.....you could fry the amp. If you want to be sure....call or email the company that makes the amp.

Sorry S|Lv3rBu||et, but I have to disagree with you here. The 12s would have the ability to hit lower and deeper than the 10s. And while it is true that 10s generally hit tighter than 12s that is not always the case.

With proper tuning you can make a 12 sound like a 10, but you can never get the 10 to hit as low as the 12.

I recommend 12s for their versatility.

Yup, the more air mass you can move, the more dB's you'll hit at lower freq's.

[S|Lv3rBu||et]

true, but the amount of air mass you can move isnt just a product of the cone size, its also the Xmax or maximum linear movement of the cone. that's why Sunfire can make a dual 8" sub that can put out 110 dBs @15hz (and move more air than an equally powered 15" driver). Its all tuning and power. All I am saying is.... dont get 12" subs just to be like "hey, I have 12" subs" get whatever sub you think will give you the effect you desire.

And as far as a 10" "never" hitting as low as a12....
Well, I have a 10" home sub that I designed to be flat down to 18hz....and it is. I know of quite a few 12" subs that cannot do that. Its all in the design man...

[DaJoker]

I wasn't saying that no 10 can hit as low as any 12

it IS a matter of design...I'm sure that the 12s made by the same manufacturer as the 10s that you mention would hit lower.

I'm assuming here that he is looking at subs of the same manufacturer and trying to decide whether to go with 10s or 12s...if he's going with the same manufacturer I would still recommend the 12s over the 10s.

You are true about the spl being a function of more than simply the size of the cone....the JL W7screate an incredible amount of SPL (usually comparable to 2 or 3 subs of the same cone size).

i think because of the amount of space available you can make the 10 sound better. Its a smaller speaker which gives you more room to work with to make it sound proper. I had a 10" jl audio bandpass and it sounded louder, lower and better than the 12" kicker comp VR sealed box i have setup now. and i believe it's because i was trying to save room and make a 12" fit in the same space as the 10". If you are willing to lose all your trunk space and build the box to its max potential than theoretically the 12 will always sound lower and louder.

[DaJoker]

gto 78, There is really a lot of space in the hatch of our celi's to make 12s sound good. I've got four 12s in my trunk, and there would still be a lot of space if I wasn't trying to go for looks.

I had a 10" jl audio bandpass and it sounded louder, lower and better than the 12" kicker comp VR sealed box i have setup now.

This isn't a fair comparison. The design/concept behind a bandbass enclosure is largely responsible for the difference in sound.

The truth is that there is ample space in the hatch of our cars to fit 2 12s...I've managed to fit four of them nicely into the hatch of my car. The added cone size with a 12 gives you more freedom to tune, and adjust performance to your taste.
