Does look like a pretty good sub. Identical performance to the PB-13 at a lot less money.

The posted numbers were for 1 meter, not two meters.

Except that you got a dts-10 for around a grand. That is a much better deal.

I have EQ and Amp so it was not quite a grand. No doubt the best bass deal was the DTS-10. Wish I could have fit 2.

Yes, I'm aware of the specifics. I still doubt the numbers.

I respect Dr. Hsu and have a good relationship with Pete, so I prefer to keep out of their threads, but this is the DIY section and the subject has been broached.
I don't know of any amp that has +6dB of burst capability, so I'd like to see more specific data to confirm that fact. Since they posted the spec, I don't feel it's out of line to question the specifics.
I'm also a bit ruffled at the recent trend to use a pro sound driver and post high max output capability at 63Hz vs 20Hz, but then post a +/-2dB response (which really means +0/-4dB, but is still shows the max numbers at single frequencies to be misleading) from 20-200Hz (or whatever).
Since the PB13Ultra is a proven entity, tested by an irreproachable source, the comparisons are already flying, but based on the manufacturer's posted numbers, which I doubt anyone with credibility will verify.
SVS, whose marketing jargon sometimes borders on the absurd, posts a response of +/-3dB 18-150Hz, but they also post a confirming GP frequency response magnitude graph which is verified by Ilkka.
The CEA #s for the Ultra show 20Hz vs 63Hz max output to have a 6dB difference, which can be said to be +/-3dB.
The Hsu posted numbers show an 11dB difference from 20Hz vs 63Hz, which can't be construed to be +/-2dB by any method.
I prefer that they just say it's a great sub for the money and leave it at that.
Why all of a sudden are we adding +6dB to a 2M GP number? GP adds +6dB to an anechoic free air number, thus the reason to move the GP distance to 2M.
Ed's, Ilk's and Charlie's efforts over the past decade are slowly being eroded and tossed out the window. As you say, that's what marketing folks do for a living, but that doesn't change my perspective.
Soon we'll be seeing under specifications:
Max output: Teeth rattling, pants flapping.
Extension: Really, really, really deep.
Plate amp: 20,000W peak (150W RMS).
Even used car retailers have to put the paragraph of micro-fine print at the bottom of the ad while the voice over is spewing BS.

Hey, maybe the numbers are all good. I love to be proven wrong. But I tend to not want to compare Ilkka's PB ULtra numbers to Hsu's own test results numbers.

-Don't give them any ideas.....My theory is they don't like to give the fine print details out because they don't want anyone to be able to duplicate the conditions and discover it's all B.S.
