Would 10 different builds of this kit all test he same? At least compared to the standard deviation of non-DIY speakers?

Added spin data to the review
Resonances have to appear in the frequency response curves, or else they are so low level that it’s not important.
A speaker is a speaker, right? Why limit your database?Due to the DIY nature, I won't be adding this to the master database.
Does the designer specify a sensitivity number?Am a bit surprised by the low sensitivity as do not use very high power amps and have not had any obvious issues driving them to high levels. The impedance chart indicates they are built to spec so am a bit baffled.
Because the cabinet made by the owner can have a large impact, as well as any building errors. The manufacturer‘s frequency response is more neutral, we don’t know if that’s due to smoothing or building error.A speaker is a speaker, right? Why limit your database?
No, at least not that I can find.Does the designer specify a sensitivity number?
For music, getting loud enough usually isn’t a concern; it’s for movies where high SPL is needed (due to higher dynamic range).Thanks @amirm for the compliments and the testing. I will add some color from my experience with these speakers. Bear in mind, am the builder and not the designer (that would be John Krutke).
- Originally did not intend to finish them at all. What you see if what is a (mediocre IMO) protective (first coat) of Duratex paint. It is will be sanded down and recoated for a better finish.
- I have used them with and without a subwoofer. Without the subwoofer and in a small room, I find the bass quite sufficient, but as Amir pointed out, it is small woofer. The designer’s site is pretty clear about the

That is a good question. On a speaker this small, it is conceivable small differences in cabinet volume, etc, could make measurable differences in bass response. If a kit comes with a flatpack, the results should be consistent. I don't have any experience with this company, but in my experience with other companies (DIYSG) offering a commercial kit, if built to spec, the results are very consistent. Just as consistent as I'd expect from any mass produced speaker from unit to unit.If I go build this kit, and my measurements are going to be different, what does this tell me?

Many audiophiles pay 10 times as much or more for LS3/5 clones with similar bad sensitivity ...82 dB...

I explained that in the intro to the review. I used to use 0.7 Hz resolution. I moved it up a few notches to 2.7 Hz. Sean Olive's research relies on frequency resolution of 2 Hz so this is a close fit. I compared the graphs between two runs (0.7 versus 2.7) and other than down in 20 to 40 Hz, there is not much difference. There is dramatic reduction in file size and good bit of reduction in test time so I like to stick with the new standard.By the way @amirm, the number of points in the measurement data seems a bit odd:
This sort of alludes to my issue with these types of reviews (not that my opinion matters) but I struggle to see how this benefits anyone but the builder if they are all going to test differently anyway. If I go build this kit, and my measurements are going to be different, what does this tell me?
I enjoy DIY projects and have considered building some “sub furniture” so this is a legitimate question and not me being snarky.
