Even though I only have a POS camera on my phone, I can try to take some pics, as well as one of sparkle, but they probably won't come out very good. I also need to figure out how to upload pics here.
As far as audio goes, I haven't been able to test that, as all I have so far are some samples. I don't even have any speakers yet!
OK, good with the black felt at least. I guess for the conclusions it might be a good idea to wait for a new sample... If the other samples are typically a bit more roughly woven variants like the XD they will appear whiter though. The UltraWeave uses a very tightly woven ultra thin front layer, which is certainly much finer than the alternative woven single layers, but also a bit more transparent in terms of light. Even though you can see through this initial layer (onto the knitted backing layers, first a white layer and then a black backing layer, both integrated / bonded) when looking at the fabric close up, however, when reflecting light from it, your eyes are only perceiving the structure of the initial woven layer. This is also the patent of the fabric, i.e. an initial ultra fine woven surface coating and a secondary knitted, much coarser one.
Using only a single woven layer of thicker threads - albeit it will a times provide a little more gain (but often at the cost of speckle as many manufacturers gloss the threads used to increase gain) allows for less air to pass through, which again leads to lower AT. A "quick test" in terms of AT is to just blow through the sample. You should make sure you include the black backing when you blow through the alternatives. Other than that, the rougher weave also has far more visible structural appearance than the UltraWeave, which basically emulates a regular PVC-based (non-AT) surface coating. So, although you might be able to obtain a little gain - let´s say 10-15% by choosing a coarser basic weave, you would loose out on the structural appearance and AT.
Higher gain is not the case for all coarser weaves BTW, for example the Screen Research 4K woven material measures a little lower gain than the v6 in our lab, but this is also quite acoustically transparent (about 2,4dB on average compared to about 1,5dB on the v6). However, again, the structural appearance of the v6 is way finer and the black backing is integrated on the v6. So, increasing gain beyond the Screen Research on a single layer basic weave, like the XD for example, is done by tightening up the weave - which again is at the (high) cost of AT...
As for the comment on speckle I am really not sure what is causing this other than the sample being somehow contaminated. I am extremely fantastisk absolutely obsessed by speckle, and we are custom bleaching the threads used in the UltraWeave to obtain that ultra matte appearance that also secures no speckle. So, again, awaiting a new sample would be my advice although if gain is your ultimate goal in this and AT is not of critical importance and you have sufficient seating distance I am sure you will be pleased with something else, we can´t win em´ all...
