Thanks for the post. Seems like a nice price for those these days. I kind of wished that I would have snagged some Classic Threes back when they were something like $300/each (a year or so ago, I think). Prices now are pretty high. I've never heard any of their newer speakers, though, and I'm curious how they compare to my 1.5s.
EDIT: Just out of curiosity, I added two pairs (the max for the promo) to my cart, applied the promo code...and the discount of 40% off shown in the cart was only from one speaker ($131) and not all four ($524). Might need to contact NHT to get the real deal unless it auto corrects later in checkout.
