He sells the kit without it so there is nothing unfair about it. If we add all of his options it may double the price and then someone claims we made it too expensive for no reason.Not adding anything inside to the X-LS would be unfair, I think.

We are testing the car as sold by manufacturer. They should not sell it that way if it doesn't perform.Then your measurements will be less important and transcendent. Simile: What is the point of using narrow tires in a sports car?

Yeah, the plans state “Lining the Box with No Rez is highly recommended.”, not required.We are testing the car as sold by manufacturer. They should not sell it that way if it doesn't perform.

To keep with the car analogy: That’s like the Bugatti coming with their standard tires, but needing their $30,000 special Michelin tires to reach max speed.
In the future though, I would like to see a DIY speaker tested bare bones and then with all the upgrades applied.
The original x-ls speakers that were sold by Mark Schifter had acoustic damping in them. It looked like polyester fiber. I had a pair. They sounded thick and seemed rolled off in the high treble. Like an enforced tube amp warmness. Evidently the kit has an improved crossover, so I'm interested in the measurements.
The vast majority of ported speakers have some sort of absortive material lining the cabinet. I thought it was silly that the C-Note's were tested with no kind of lining whatsoever. And it is silly to test this speaker sans any lining as well. If I were building these kits I would designate a standard lining material for all ported speaker kits that don't come with it. Something like polyfill sheets, egg crate foam or sonicbarrier.
Those who listen to good recordings and know a bit of electroacustics, applied mechanics and transmission waves are sure to add cushioning....

The problem with this is that Amir has a large backlog of testing to do. I think it is highly unlikely that he will go back and test the same speaker with damping added. He didn't do that with the C-Note did he? And yet the designer came and recommended significant damping. No the kit didn't come with that but it also didn't come with binding posts, screws, wire, wood glue or solder. The GR kit comes with more of the small parts but it doesn't come with the enclosure so clearly it's not complete. Danny has stated No Rez is highly recommended and to me that justifies it being installed in the speaker to be measured.If there are results that clearly demonstrate a need for dampening, then can propose a fix.

Well, after Maty's post, my pic seems rather sad, but will add some color from my own experience that may help others considering a purchase. As you can see, the kit includes some information. Note I kept the smaller parts in their bags just to keep them from being misplaced. A few notes now that I have unpacked. The tweeters are hefty and, if that implies quality, am looking forward to working with them. On the other hand, the woofers tend the other way, and are much lighter than many others I have (but will reserve judgement as they are also much less expensive than many others).
As for the instructions, they are pretty light and so, despite the nice parts coverage, not near as complete. A few obvious questions might be how to layout the crossover (only schematic supplied), where/how to mount it, and why heat shrink tubing is supplied? None of this is addressed. Fortunately, the crossover topology is simple and so I will do a layout later. As for wood, it appears I will have more than enough using my usual 2x4 foot sheets of 3/4 inch MDF (1 sheet is more than enough for one cabinet). More to come...
