Last year I auditioned 3 NHT speakers - SuperZero 2, Absolute Zero, Classic 2. Great sounding speakers with superb detail and clarity but, as cel4145 alluded to, noticeably lacking in the low end. And (to my ears) they were even a bit thin in the lower-mid-range. That being said, I think the Absolute Zero and Classic two would work fine for HT/TV if you had a very good, accurate sub. A cheap sub, i.e. thumpy or blurry, might not play/blend well enough across a higher crossover.
(FWIW at the time I was comparing the NHT's to the KEF Q100 which I kept - music listening was equal priority with HT listening for me, and I personally really enjoy the KEF's imaging.)
To my ears the Monitor Audio Bronze BX2 is also a very nice speaker, and, it's come down in price in the last year ... too late for me
I actually own the SVS SB12-NSD and highly recommend it. It is unusually small for a sub in it's class (basically a 14" cube), and in my room/space that was a priority. Like several other highly recommended subs in that price range (Outlaw, Rhythmik, HSU) is has excellent detail, accuracy, clarity, dynamics, etc. The caveat is, being a smaller sub it doesn't play quite as strongly below 20hz as the larger PB version or some of the other, larger subs mentioned. But that has never bothered me.
