I think this was only an issue when the double impact took off back in early 2018. My grills were delivered with my speakers in July. A friend across the US also received his grills with the speakers in Sep this year.
Tekton custom grills
There are some active discussions concerning the delivery of speakers and specifically speaker grills for the incredible Tekton Speakers. But nothing on this forum. I'm now nine months waiting on grill delivery. Anyone else??
