This was my contention with importing the KH150's - they are well above that $800 break point - where as the KH120II's are easily under that break point "per unit". My research yielded many many KH120 importers, but few to no KH150 importers, and basically zero information on actual tariffs that were imposed. That was why I started this thread.
And to update - The single KH150 was officially processed as "no tariff" even with an officially declared value of ~ $1200 USD. I was only charged a $4 "processing fee" on that one.
About 3 weeks after the pair arrived, I got an invoice for approx. 2% tariff ($48). Paid that no problems (and 2% was the anticipated tariff rate for active speakers). Not a peep from Texas regarding sales tax requests.
One thing is for sure - I won't pay any taxes I don't HAVE to

Double and triple taxation is MORE than enough thank you...
Anyway - now that MusicStore followed suit with Thomann and ceased Neumann exports to USA - I guess it's a moot point - but saved me around 1/3 of US Retail...
