i have been looking at get a/2 subs??? lookikng for a firmer bass, looking at 10" x 2??? any particular brands??? models??? price is not really a prob. so fire away, oh by the way if i go down this path im going to run in parallel on a mono amp. was thinking about 300-400wrms???
cheers craig

If price is no object go for Velodyne active servo subs.
From what I've heard they are the best, period!

you must have some sort of budget limitations.

my suggestions:

Image Dynamics IDMAX12V.3
Boston Acoustics 12.5LF
Focal 33WX
JL Audio 12W7
Adire Brahma
PG Ti 12D Elite
Diamond TDX 12

how much do you want to spend on an amp/s for these sub/s?

Why do you say that Mat?

For some people budget is no issue.

Anyway the Velodyne subs would come in under $4k.
(From memory they are about $1800 each)

he was thinking about putting 300-400rms into subs he is going to buy with no budget limits.

Well that is the sort of power the Velodyne subs will work really well with.

These subs actually limit their output if fed too much power.

I would dare say that they would work better than say a W7 as the W7 is desinged to work with a lot of power and would not really b efficient enough to make the ost of the power.

If cost isn't an issue, then there is no reason why a W7 will neccesarily be a bad choice. Just because it can handle a lot of power does not mean it needs it.

for sound quality iw ould go for 1 or 2 12" subs. 10" are a bit too punchy for SQ. JL are a very good brand, i highly reccomend them

You can make a 10 inch sub sound however you want by putting it into the right box for the application.

15s can b "punchy" and 10s "boomy" depending on the box you put them in.

You can generaly tune an enclosure to make subs sound how you want, some are easier to manipulate than others.

Having said that I think it is always best to choose a sub that is going to suit the application as best as possible first.

There is no point using an RE MT for say an SQ car in a low power class IASCA event.

I didn't say the W7 would b a bad choice, I think the Velodyne would b a much better option though.

Well done guys!!!


Someone asks a question, and you guys get into an argument!


BTW. Some of the Rockford range are good for SQ. Best idea would be to listen to as many as possible and then choose!

Cheer up, who's argueing?

Expressing alternative opinions in an open forum harld screams arguing.

With that said I do agree with HISPL. Over 60% of your speakers "sound" charracteristics are generated from the box you put it in.

Agreed, and also I think that the best way is not to think what sub you should get, but how much area that you can allocate for the sub box. With that you'll get an indication of volume of the box, then you can start searching for a sub that plays really well and fit in that volume.

Am I right?

But if you want a suggestion, what about a pair of Scan Speak 10" subs? Code number 23W/4557T00. Have a look at www.d-s-t.com. Dont know if you can get it in Oz, but worth a look/search. I'd probably do it that way, just trying to be different. They look cool as well, depending on the install & cosmetics.

Cheers,

I've always believed that "in general", a good ten inch sub will do a better job of maintaining the correct pace and timing of the music.

I also agree that the box has alot to do with the final result.

If I can recommend one sub even without knowing anything else about the application and your tastes, I would like to suggest that you look at what the Infinity Perfect 10VQ can do. It's going to allow you to adjust what you get even when the box is built and finished as you can remove and refit different inserts into the back of the sub magnet changing it's sound. It's one heck of a sound quality sub that with enough power (and you have enough) will go pretty darn loud.

I'm not biased. I have two of them.

while we're on the topic of sub enclosures and sound characteristics, I've noticed that the specification Vas seems to be very decieving, I was under the impression that this signified the optimum internal volume of the enclosure. But in most case, the recommended sealed enclosure is much less than this?

what happened to the old school 'stay within 2 basket sizes' rule? JLW7 gets my vote tho

"Velodyne" Do this brand make sub for car?

I've seen a few of them arround in WA.
There was a black Silvia with an SQ install done by Car Stereo City that had one in it, and a heap of Audioart & Technologies cars.
Nice subs if you can find them. :-)

The best SQ you hope for would come from the Velodyne or Focal subs as already mentioned. However, mounting two in a dipole arrangement would give the best SQ period (given a properly designed dipole enclosure).

Well dipole may be a good idea, unless you were to use it in a car...... :wink:




I'm not sure where you got this nugget of misinformation, but the VAS does not signify the optimum enclosure volume. In fact there are very few cases that I can think of where they would even be similar. The VAS is only one part of the picture when designing an enclosure.

Velodyne home theatre subs are all hype, having listened to a couple they arnt anywhere near as good as people say (pretty much like bose, but no where near as bad )

Haha, RXImpreza are u still reading this all this anymore?

But u probably should come up with a budget...

And Matt69 is probably right, if he is driving a RX impreza he probably doesn't have a bottomless pocket or else ge'd prob be able to afford the "W"

guys, the tech crew at JL admit that the W6 and W7's sound the same, however, the W7 will remain linear, when fed power beyond what the W6 can handle.

i use and recommend teh brahma, but there are plenty of other subs around that will do an awesome job, including most of those mentioned above.
audition them if you can...

personally if was buying now, i'd be looking at the TDX12", simply because it's easier to source than teh brahma, and appears similar/marginalyl better on paper. haven't heard one though...yet

We ran a 10" Velodyne of a 500Wrms Rockford amp and you could barely hear it. It did sound pretty good though! LOL

The W6v2 right..not the W6?

The W6 isn't anywhere near as good as either the W6v2 or the W7. It doesn't use the same technologies that they share.

But yeah..I've spoken to Custom Car (Aus distributors of JL) and JL Audio international, they've both confirmed the W6v2 and the W7 sound virtually identical..just that the W7 will maintain it's SQ at really high listening levels in high powered applications. (we're talkin close to the 1000wrms mark here).

If you're looking to run only 300-400wrms into each sub, the W7 would be some $500 of money that you shouldn't have spent. U won't reap the benefits that it will provide over a W6v2 cos that sorta power is WELL below the limits that a W6v2 will reach. Not saying the W7 won't sound good...on the contrary it'll sound bloody fantastic if set up right....just not any better than the W6v2. Maybe slightly less output on the W7 cos it operates at 3ohms, and not 2ohms like the W6v2. So won't be utilising as much power from the amp.

Also don't forget that JL Audio's latest showcar, the Mini that won Best Sounding car at the 2004 CES uses a pair of 12W6v2 woofers for sub bass. This replaces the pair of 13W7's used on one of their older showcars.

Just some food for thought...I was thinking thru a lot of these issues when I was making the choice myself.

That said though...the W7 still reigns supreme at the top of the JL line.

Wouldn't matter if you put 6 of them in a wall with 3kw. LOL

take a morning off and do the rounds of your local carsound joints... listen to as much as you can. drag along your best known/fave cd's/dvd's for testing and establish what you want to achieve before you set-out (pure sq/sq with spl capability/straight spl/budget.. etc...

at the cheaper end i liked the peerless xls subs, although you won't find one in your "average" car hifi shop. the 10w3v2 sounded nice for not much more money, and you can hear them powered by (usually) a jl 1000/1 at pretty much any jb. the dynaudio subs are wonderful and incredibly accurate, but dont move as much air as some of their competition. above that, the adire brahma (mmmmmm), jl w6/7, focal utopia and velodyne subs get my thumb.

best of luck!

The IDmax is definitely better than the W6 v2, and equal to the W7. Dont let the prices of them misguide you. In the states there is only a very small difference in price between the IDMAx and the W7 unlike here in Aust. With 300-400W rms, it will still sound very good and go fairly loud. So it is another sub you should have a look at.

in what ways is the id max better other than the fact that it can go louder?

it is important to think about how you're auditioning subs for a sq install. subs don't sound tight (http://www.installer.com/tech/tight.html). its important to think about what's going on when listening to subs instore, ie. what other speakers are playing, how they're set up(amount of power, crossovers, active/passive, etc). compare the setup with mid bass/ highs that will be in the final setup.
thoughts?
