In my field, we would be contacting each other, trying to figure out discrepencies (perhaps you are trying to recreate some results from a journal paper, and something is just off, or perhaps you need to spend a lot of time discussing a client's test setup), and really get to the bottom of things, before making anything public, especially if it is a really gross discrepency.
There is no gross or any discrepancy for that matter. My impedance measurements are simply higher resolution than what he and others post. Rick for example post the impedance during the build and it is smooth as he shows:
Further, the frequency response matches his. You want to explain how one gets that to match but with a faulty build?
I gave the kit to Rick to build because he is extremely methodical. He followed their instructions to the letter and beyond such as rounding over the edges. If Rick can't build this kit properly, nobody can. I don't know how anyone with a straight face can complain that something is wrong here.
All of this aside, your larger point, I agree and I tried. The problem is, the other side doesn't want to have anything to do with us. Here is the interaction:

Hi there. This is Amir from Audio Science Review. I am getting interest from my membership to test your new Little Giant speakers. Are you able to loan me an assembled speaker for testing? Doesn't have to look pretty unless you want it that way.
Thank you,
Amir

Hey Amir,
We have already measured and tested them. We really don't need measurement confirmation.
But if you have a high quality audio system that you can use to actually listen to them as designed, then we might be able to work something out. And then you can measure them all over the place. I am not concerned about how they measure. Like I said. We've done that.

Thank you for the response Danny. Your measurements are gated so lack resolution in lower frequencies. And at any rate, are not compliant with CEA-2034 which allows research into audibility of measurements to be applied to them. You also have not shown any distortion measurements. These are the reasons members are looking for me to measure them.
As to listening to them, I always do that. My system for testing desktop speakers is RME ADI-2 DAC driving Purifi based amplifier. These are world-class products. If they are to be tested as stand-alone speakers in a 2-channel system, then I use a Mark Levinson Reference amplifier ($20,000) driven by Matrix Audio streamer ($2,000). Is there a specific requirement you have here that owners need to have to buy them?

Hello Amir,
| Thank you for the response Danny. Your measurements are gated so lack resolution in lower frequencies.
The levels of resolution in that range are perfectly fine. We can take a near field response of the driver and the port to really see the roll off. As I am sure you know, ranges below 200Hz are really more a factor of the application and room that they are used in. So while I could provide a measured response down low, and so could you, what really happens in that range is really a variable that we can't control.
| And at any rate, are not compliant with CEA-2034 which allows research into audibility of measurements to be applied to them.
I am not at all concerned and neither are our customers.
| You also have not shown any distortion measurements.
Distortion measurements are of little to no value and the most misunderstood of all measurements. Audible differences in low distortion devices are difficult to hear at best, and nowhere near the real distortions introduced by stored energy of a driver, frame ringing, cabinet resonances, and even crossover parts.
| These are the reasons members are looking for me to measure them.
Not too many of your members are our customers, and most of our actual customers don't think very highly of your site and its objectives and beliefs.
| As to listening to them, I always do that.
Well, when you reviewed our base level X-LS Encore you only listened to one speaker. Our customers thought that was a bit of a joke.

There are no requirements for enjoying music or our products. Our customers enjoy our products in budget level systems in their garages to six figure systems set up in treated rooms and everything in between.
I do expect higher standards for reviewers though. Those that are really giving feedback as to how good a product sounds should be able to hear and discern what a product can do versus others.
My concern isn't so much with just the gear you use, but the listening room set up, room treatment, speaker placement, and quality of everything in the chain including cables. If you are going to review our products it would be nice if you can really hear what we have worked so hard to create.
As we both know, we are from different camps (so to speak) and have very different experiences and conclusions. You specifically are one of the guys that I would love to have over for a visit. We can hang out, listen to music, eat some Texas BBQ, and bridge some gaps. You can come find out if there is some validity to what I say, or if I am completely crazy and delusional. I bet your followers would love to hear all about that visit.
What do you say to that?

I am unclear why you are giving me all these arguments Danny. If you think anything I write is of no value to you, then that is all you needed to say. I will communicate that to my membership and consider the matter closed.
As to coming over, I love your food and hospitality whenever I have been to Texas, this exchange notwithstanding.
