Zombie post.
In 2001, 21 years ago, calling 14mm excursion "generous" would be understandable.
Not in 2022.
The SVS SB16-Ultra has 65mm Xmax.
Good call on the Date
I did not notice at first
I was thinking in my head
" Dont you know there is dual spider drivers with 60 to 70 mm Xmax these days "
I find it ridiculous ,
But hey, everyone is welcome to have fun with whatever they want to throw their wallet at
I found the 2nd post to be more sensible.
If you really need that much excursion , just use 2 drivers

You are correct.
SVS states a 13.3mm Xmax for the SB-1000 Pro, which appears to align with CEA-2010-A peak output/distortion tests from multiple sources compiled by @sweetchaos in his Subwoofer Comparison.
A bit less than half the 65mm peak to peak excursion (65/2=32.5mm seems to correlate with the SVS SB16 Ultra's CEA-2010-A "pass" at 20 Hz, around 102/103dB at 2meters ground plane when adding +6dB to make up the difference between 2meters and one:
CEA-2010 is an industry standard first published in 2006 (updated as CEA-2010-A in 2012) that specifies a method for measuring maximum SPL before distortion reaches a "fail" level at various frequencies, requiring progressively less high order distortion to "pass".

The SVS SB16's 20 Hz output appears to be around equal to Josh Riccis Data Bass CEA-2010-A measurements of the 21" (16.5mm Xvar) B&C21D115 in a sealed box.
