    NLA grill cloth?

    Yes it is, the fabric from Dorr Mill is very close but in my opinion not worth the many times the cost of what I used. But of course each person has to make their own choice.

    NLA grill cloth?

    I must apologize for the wrong link for the caydo fabric. It is sold now only by amazon. the link is https://www.amazon.com/Caydo-Needlework-Garments-Accessories-62-Inch/dp/B075Q9CV33/ref=sr_1_5?ie=UTF8&qid=1545222378&sr=8-5&keywords=caydo+linen+needlework+fabric When I did two of my NLAs I reused the black under layment and stapled the new cloth over that after I steam ironed the new cloth. It was pretty easy and came out looking really good according to the "Boss" (my wife). Thanks, RickB

    NLA grill cloth?

    Here is a picture of the NLA grill. The source for the material is caydoonline.com and the p/n is X001KPU2XF. The weave is tighter than the original but it is very acoustically transparent and passes my listening tests and has Diana's approval. The 2 small lines are threads on the grill now removed.

    NLA grill cloth?

    I have replaced the grill cloths on one pair of my NLA. It is a tighter weave but acoustically pretty transparent. I will post some pix later now on to more coffee at 7:05AM!!!!

    New AR drivers.

    Good Morning and Happy Thanksgiving to everyone! Frank thank you for the link. Also are you finally done buying Microstatic tweeter arrays at the auction site? It seemed every time a set came up and I tried to win that auction you seemed to swoop in and snatch it away(good job)lol. I will if I have to when I can get to them rebuild and test my 1 pair of 2ax's and two pair of AR3a's get some of the new tweeters(or have Chris rebuild them)and midranges.

    How Long Have You Owned AR Speakers?

    Hmmm. My first set were AR2xs for my second system in 1967 sold them in 1968. Next system AR2axs still have them, now along with 2 sets of AR3as another set of newer style AR2axs and a set of AR7s. And many more of other brands and not enough room to set all of them up-damn it-lol.
