someone just bet me 1000$ that..

im limited to one 10

he means have an extra on hand in case the first blows.

Basically at the 13W7's full displacement (4” peak to peak, which I know it can do, at least the HTW7 can), it would take standard 10" cone moving 8.6" peak to peak to match it….. That will never happen.
Simple displacement here. (unless you're talking about high frequencies and under extremely high power levels where power compression and low indutance may lend to some other driver's advantage, then the 13W7 will best all 10's for output)

The only other chance you have is if you make the system different . In other words, a horn load 10" against a W7 in a sealed box, or something of that nature. Of course, if he does a very efficient system too, then bring cash.

Where the hell did you pull 4" peak to peak excursion out of? Its 2.5 inches, and it says it right on their website. Are you saying that one of these high output SPL subwoofers handling 4kw+ on a burp couldnt beat out a 13w7 which could only handle approx 1000 watts rms (despite the difference in cone area)?

You can throw a million watts on a driver, all the power is doing is allowing the cone to move further. SPl is based on displacement, power handling doesn't have a "huge" effect in this regard. High power handling allows you to more safely push a driver to it's absolute limits, it doesnt' necessarily mean the driver will be louder, or move further in general. In a sealed enclosure, beating a 13w7 with a 10 is going to be hard. The w7 can move quite a bit, combine that with it's added cone area and even SPL drivers with 60mm+ of xmech are still arent' making up the gap.

Long story short, if he's using a sealed 10, even with buttloads of of power on it, he better be prepared to pay up. His only real chance of winning is to use a ported box, to allow the box to make alot of the noise, then use lots of power, to attempt for force the sub to move a bit near tuning.

Would never have considered it being in a sealed box, unless I just skipped over the OP saying it woudl be in a sealed box with a ton of power. Definitely would have to be ported, and some kinda monster little sub with a ton of power to it. Good luck. heh

Its 4" max displacement --it says so right on the website. In fact it’s a video too. Like I said, for higher frequencies this will not matter as much, but just know, at any given frequency, the 10" will have to move twice as far to match the displacement of that 13.5” cone.

My advice is get a 10" driver with low inductance and high BL, don't worry about Xmax so much because you're going o bet him at a higher frequency if you’re going to do it at all. You don't need 4000 watts to do it either.

Hows 15000watts vs. 1000watts in a sealed?

 

[Blazin_Jason 10+ year member]

Same TYPE of vehicle (SUV, hatchback, sealed trunk, etc.)

Sealed box (least amount of variables)

Amp of your choice (obviously different subs require different amounts of power)

Wiring of your choice (again, different amps and subs require different wiring)

No sound dampening

Your 10" sub cannot exceed $350 new

That's probably not optimal though. I would rather see you stomp him with a TommyK setup. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif (10" type r)

thats what i was gonna say

you already got a zx2500

get a 10in type r and build a badass ported box for it

then take this guys grand and slap him with the stack

LOL, I will have video of stack slap!

Whose to say that kid is going to be pushing that W7 to its mechanical limits (and thus displacement limits) anyways?

Real world experience > whatever book you are getting all of this technical jargon out of. Pretty much any and all spec sheets and graphs people can devise about speaker performance can get tossed out the window once you set up the speakers in a car and run actual tests.

To give you an example of what I'm talking about, i'll use some of my personal tests

10" RE SX: RMS power handing: 1000 watts, XMAX: 22 mm, sensitivity: 85.2 dB

10" Alpine type-r: RMS power handling: 500 watts, XMAX: 18.1 mm, sensitivity: 83 dB

Now by your "technical" definitions, the SX should be louder correct? After all, it has higher power handling, more XMAX, and has more sensitivity to boot. Well guess what, the type-r beat it by 2 dB, all things being equal (box size, port area, actual power, peak frequency (44 hz), vehicle, everything).

Having more excursion and potential displacement does not always equate to higher SPL scores. There are WAY more factors than that.

Beat him with a 10 inch W7.
