Hi, I was asking the legendary question... Is a 12" can be as fast as a 10" ? I found that the speed of a subwoofer is determined by its inductance, but i found a 15" has more inductance than a 10", I supose that 15" isn't faster ?? What kind of subwoofer should I look for, I listen to mainly techno, but hiphop-rock too... I'd like between 400 et 500 wrms... thanks !!

typically, a 10" will not be as deep as a 12", but it will be more precise. For the music you listen to, I would look for a DVC 10".

well thats what I think... but Forbidden told me i should go with a 12" ! and why a DVC instead of a SVC ?

Do a search on this thread. It has been discussed before. With identical drive motors there is no "speed" differance between 10" and 12" subwoofers.

can a 18 wheeler go faster than a corvette?
When my uncle owned a shipping company, one of his drivers had a Peterbuilt 18 wheeler that could do 140 in 18th gear....until he was arrested and the truck was impounded in California.

well i figured that with identical drive motors.
Then your previous post didn't make any sense.
Simply put, a 15" can be just as fast and clear as a 10". It is a myth that 10"s are fast and 15"s are slow. ------------- New Project: 2003 Pathfinder

well..as for the speed of a woofer....isn't that the same thing as asking what's heavyer, a pund or bricks or a pound of feathers? the sub will see a signal from the amp that change's into the frequency (40 HZ for example) seems to me that the 40hz is how fast the sub is going to move from where it started to it's peak cone movement and back to start again in (40 times per second for 40hz) 1 second...is it not? so looking at it that way, if you have a 10" sub and a 12" sub playing 40 hz then both cones are moving in and out 40 times in a second and there for both cones would be moving at the same speed...the only difference would be how each subs able to play that 40 hz, a 12" will play it better then the 10" just because the larger the sub the better the subs able to play lower bass notes.

stang.
"Speed of the woofer" or "transient response" generally means the time required to respond to changes in the signal, not the frequency of the signal itself.

Which is heavier: Pound of gold or pound of feathers. Actually...the gold. Gold is measured on the Troy scale, only 12 ounces, but heavier. What does this have to do with this thread? Absolutely nothing. ------------- The Flakman

I have both 10's and 12's and can say that without a doubt, their speed directly mirrored that of the car. If I was going 100KPH they also went 100KPH, I could never seem to outrun them

hmm.. so everyone seems to say that a 12" could be as fast as a 10"... but not as clearly ? 10" for techno, 12" for hiphop, what if i listen both?  And what should i look for a good sub (material, cone, .. ?)
Posted By: kfr01
Date Posted: August 23, 2006 at 10:41 AM
wavdj:
No. Ahhhhhhhh!
A 10" can be just as clear and just as fast and just as everything else subjective as a 12".
Whether a sub is "good" or not can't be determined by simply looking at its materials, its size, or even its T/S parameters.
Unfortunately, this is where brand name and reputation really does come into play. Does the manufacturer use good quality control? Is the subwoofer a good design? Is the motor design low distortion? Is the design reliable?

ok ok ;) then.. what are these good brand ? JL Audio ? Infinity ? Alpine ?
Posted By: haemphyst

JL or Eclipse. The Infinity and Alpine are marginal gear, until you get into the higher end stuff.
For the money, the Eclipse aluminums would blow your mind, man! Check 'em out!

More is needed before we can make a recommendation.
How much volume (space) in your car are you looking to dedicate to your subwoofer install?

well i have place... i have the new Yaris 2007(Sedan, not the hachback) Depend on how i'll put my sub in, i think ill be ok for any box. I'll have a sealed box...
Posted By: wavdj
Date Posted: August 24, 2006 at 2:04 PM
probably go with a 1feet X 1 X 1... well, the best size for the sub. that is recommanded...
Posted By: cloak559
Date Posted: August 24, 2006 at 2:37 PM
Well, for single 12" your looking at about 1-1.5 cubic feet for a sealed enclosure, depending on the subwoofer. Most people just buy pre-fab enclosures, but I would advise you to build a box to your subwoofers specifications. That's really the only way to get the most out of your system... Out of the two drivers you've picked, I would go with the Eclipse, just because i've had bad expiriences with MB Quart subwoofers. But either one you pick is up to you, I dont think youll be dissapointed either way...They're both rated at 500w RMS and have a dual 4ohm impedance. So, you're going to want an amp that will do about 5-600w RMS @ 2ohms...I would go with either a Kenwood KAC-8152D or a Hifonics TXi 7506 ...Both great amps IMO.... ------------- '89 Mercedes-Benz 300E

Whatever you do, do NOT skimp on the quality and accuracy in which you build your enclosure. It will make or break the sound quality and performance you are trying so hard to get. ------------- The Flakman

Another question.... Whats the difference having a Sub DVC 2ohm and a DVC 4 ohm ? Is one better than the other ? Instead of wiring it in parallel, ill wire it in series? so its the same thing ? (Its gonna be on a mono amp)
Posted By: kfr01
Date Posted: August 29, 2006 at 1:26 PM
The primary difference is just that you have different wiring options.
See the "Woofer Wiring" calculator on this site for more information.

The only reason for DVC 4 ohm and DVC 2 ohm is to give you more possible wiring configurations. Match up the amp and speaker DVC impedence options for your situation. If want to run 2 DVC subwoofers and have a 4 ohm load on a mono amp, get 2 - 4 ohm DVC subs and wire series/parallel for 4 ohms. If you want to run down to 2 ohms with 2 DVCs, run 2 - 2 ohm DVC subs wired the same. It all depends on your specific application. The 2 ohm and 4 ohm subs are the same, just depends on how you want to wire them up.

It is still going to depend on your amplifier choice.
Dual 4 ohm wiring options:
Mono amplifier
8 ohm mono load
2 ohm mono load
Stereo amplifier
8 ohms bridged = 4 ohm load per channel
4 ohm load per channel, stereo mode
2 ohms bridged = 1 ohm load per channel
Dual 2 ohm wiring options:
Mono amplifier
4 ohm mono load
1 ohm mono load
Stereo amplifier
4 ohms bridged = 2 ohm load per channel
2 ohm load per channel, stereo mode
1 ohm bridged = .5 ohm load per channel
