I dont care what the company says about there rated Xmax.....
My HW and SS XXX have about the same amount of Xmax as compared to my RE XXX (05)

I even have a vid of my SS XXX at full xmax.

iam just going by what thye say, dosnt matter to me. all i know and care about it the fact that they can get very loud and sound preaty good doing so.

check out thier web site, they have it listed there. i wont know untill i get my 3510 installed but my 2510 gets over 2" of excursion.

Sorry, I said that in a bit of a snotty way. I know that DD doesn't know how to rate Xmax. The 9500's have ~15-18mm of Xmax depending on the motor based on testing done.

omg'z the excurrrrrrrrrrrrrrrshun

What does "useable excursion" mean? In DD parlance, that must mean something totally different than Xmax, because the 3500's and 9500's are not even close to that.

Could it be the combination of the cones movement both forward and inward combined?

actually i think it dose. so that would mean abot 1.5" one way or so.

Ha ha. I would say the fact that companies use different methods of rating xmax. I can't recall the most common method, But basically the xmax isn't the total real usable xmax, it is the xmax within X amount percent of its max BL I do believe. But of course you know all this because last time I checked you are one smart cookie on speakers //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Adire mk1 brahma, nice xmax.

You want xmax //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif. Check out the 2006 car audio mag directory issue. RE audio has a XMX 18" and 24" sub listed at 8.9" of xmax The 18 is 73LBs and the 24 is 81LBs //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif. I will try to post pics of the mag and listing It sounds just like adire's old parthenon setup!

Just by looking at them.... there not identical... but the HW i have has like 15 mm of xmax and the RE XXX has 32 mm... twice that of the HW... but by looking at it... They look to be about the same. My HW has some throw to it

HOW CAN I SEE THAT VIDEO OF THE SS XXX

I'm quite impressed that your eye can see a BL or Cms curve; perhaps we can finally do away with $20,000 equipment to do the same.

Guys, Xmax is not synonymous with excursion. It stands to reason that a driver with high Xmax has a lot of excursion, but the opposite is not necessarily true. Xmax represents a distance the driver can travel without exceeding a particular distortion threshold; sure, the 9500's (or HW's, in your case) have excursion beyond that point, but I believe the goal in any system is to play the music; thus, playing your subwoofer in a way that induces distortion is senseless to me or, at the very least, we can agree that added distortion is a detriment.

In SPL competition, you must balance improved linearity (lower distortion) with efficiency, which is why DD doesn't make a driver with more than 20mm of Xmax. That's not to say that every subwoofer should have 20mm of Xmax; just saying that their high-end drivers focus more on narrower bandwidth SPL than they do wide bandwidth accuracy.

my vote goes to the 13av.2, that video is nucking futs
