2 13w6's sealed.

I'm not sure if they will handle the power. And they are a little pricey just to have the jl name.

Yeah, 2400W at 1 ohm is bad a**.

What about fi Q's? 12's or 15's.

But the website is scrogged.

If space is a concern, I would try to stick to a trio of 12's or dual 12's. Going to 4 12's isn't going to gain you much. So you've got 2400 watts, and if that doesn't change (lets just assume that your amp does the same output into any Ohm load) you're looking at 1440 cm^2 of surface area with 3 12" subs. With 4 12's you're looking at 1920 cm^2 of surface area. 4 12's has 1.3 times more surface area compared to a trio of 12's, which is good for about another dB and a half which is barely noticable.

I would stick to 3 12's.

Also take into consideration mounting depth. If you think about it, that's the one factor that takes up the most room in your install. Deep subwoofers do look really cool (I'll admit - I've owned a LOT of them), but they're a pain in the butt when you try to squeeze them into a vehicle. Since an enclosure is going to be a box (more-than-likely), the factor of cubes works well in your favor for increasing enclosure size.

Sure you can make the argument that deep subs offer deep enclosure sizes, so that gains you the ft^3 that you need. That's certainly true. But now you've got 1/2 your trunk taken up (it's all about ft^2 when it comes to cargo space in a trunk) because you've got an enclosure that's 12" deep. If you had an enclosure that was 6" deep, you have double the ft^2 available to haul stuff around. Not to mention it looks better IMO.

But that's just my two cents worth. I guess it comes along with dealing with big, deep, subwoofers for eight years. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

But hey, aren't we talking about SQ here? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif How did SQ and 2400 watts end up in the same thread anyway?

Tis a shame you can't have any sort of decent displacement with a shallow mount woofer...so you have to make up for it in cone area...

Yeah the box might be 3-4" shallower...but when you have to add another woofer to get the same amount of output...you've now taken up more volume out of the trunk than you would have had you went with a 'normal' higher excursion driver...

Gain 3-4" of depth with a shallowmount...but at the end of the day loose it because you need another 13x13x5 to make up for the displacement that the woofer does not have...

So in all reality, your back at square 1.

To the OP: If space is an issue, do an infinite baffle setup...no box, problem solved. After all..it's about cubic feet when we're talking cargo space...right? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That's assuming quite a bit isn't it? So are you saying that all shallow mount subwoofers don't have any decent amount of displacement? If all of them had around 5mm one way, I could see your point. But when talking about sealed enclosures (as the OP asked about), and in particular, small sealed enclosures, you're not going to get a trio of 12's moving any more than 30-40mm total anyway, so you point is moot.

If everybody goes around assuming they're going to use the 25mm of one-way linear travel in the subwoofer they bought and they're using a small sealed or small vented enclosure, they should do a little more reasearch because they're not going to. Not to mention the plethora of electrical upgrades needed to supply the extra amplifier(s) necessary to get a subwoofer such as you mentioned to move to its excursion limits.

Why pay for the weight and depth if you're never going to use it?

...and I could have sworn I put ft^2 when talking about cargo area...but maybe it was ft^3. Hrm. Let me go take another look...yep, I put ft^2.

If you used an infinite baffle setup displacement is key, sealed applications displacement is key.

My point is not moot, what happens to excursion when you drop an octave in order to achieve the same output? You won't need to get an extra amplifier if you are using a IB setup (which would save the most room) If anything you will get to full mechanical limits with ~250 watts or so on a 1000 watt rated woofer. That is if the suspension is tailored to a IB setup and the motor Q's are in line to get the type of response curve that is needed...

Displacement must double right? Well if it can't double because the cone will slap the basket at 14mm rearword then you have to have another driver to stick in there to make up for the output that you don't have correct?

Why would you look at square feet in a trunk? It isn't a house, your not laying a floor plan out, auto manufacturers do not say you have 6 square feet in your trunk. Your not looking at surface area, in a trunk it is a confined space where volume, or cubic feet is key. Unless your stacking sheets of paper or something that is completely flat, square feet isn't what I would call relivant...

Infinite baffle is where it's at. Screw the box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Interesting.

IB would certainly make sense here. The Icons will provide you with the excursion you need for such a setup and since you have a beefy amp, you will have plenty of headroom to drive them. The install will be fairly straight forward and you won't lose much trunk space as a result.

IB is the way to go if you are after accuracy and tonal balance. Having 3 or four Icons will give you volume if/when you need it too. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Best,

I thought the OP was asking about small sealed enclousres, but if it's moved on to IB, that is another story. For IB, you need stroke...lots of it to play low.

You still haven't answered my question about shallow subs though. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And car manufacturers list cubic feet of cargo area, not square feet. But what are you concerned with when put something back there with your sub? How high you can stack it, or much floor space you have? I guess you look at how high you can stack it. I look at the available footprint. Maybe I'm nuts though.

 

[NDMstang65 10+ year member]

I answered it in the previous post.

So you are gaining 4" of depth, but to get to the same amount of output you have to add an additional sub...

Either way your loosing cubic feet of volume, or square feet of floor space. Whichever way you want to look at it...

You honestly think the vast majority of the online community doesn't driver their woofers to their mechanical limits?

Thanks for the input everybody. I don't think i'm looking to go IB, because of the output factor. I'm still looking to get a decent amount of output, and thats why i have 2400w+ to work with. I'm looking for a small sealed enclosure still. If need be i will add polyfill also. When will the release on the new mags be electrodynamic? Those were also one of my options.

I'm thinking towards either ssa icon 12's, new mag 12's, rlp 12's, or idq 12's. I think Electrodynamic made a good point on whether to do 3 or 4 12's, so i think i'll stick to 3. Things are still pretty much out in the open to what i am going to decide on. If i come across a good deal on something, i will probably go with that.
