So I was looking through my local Craigslist and I came across an ad for some nht speakers. It comes with nht VT1's with matching Center, pair of nht 1.3a's and 9 super zeros and 1 Super Center. The asking price is $300. I would be using them in my living room setup 18'x16' with openings to the kitchen, hallway and a study. I am currently using polk rtia3's for my LCR and polk rtia1's for surrounds and height speaker's (9.2) with dual HSU vtf 3 mk4's. Would it be worth the $300 and also would it be any better then what I'm running now?
