I didn't realize how important timbre matching was until I bought a new center speaker to match my main's. I have JBL ND 310's for my mains and was using a AR2C for my center thinking that a more expensive speaker is better. It never sounded quite right though, and I couldn't figure out why. So I bought a bigger and badder receiver to give it more power, but that just accentuated the difference between the speakers. So, recently I found this forum and it was suggested that I try timbre matching, getting the matching center speaker. Reluctantly I bought the N Center ll which is the same series as the ND 310's and lo and behold my HT sounds great. So how can a $84.00 speaker (N Center ll) sound better than a $500.00 speaker (AR2C). I don't know but in my system it does. Now my speakers are Mains - JBL ND 310 Center - N Center ll Surrounds - JBL N24 Subs - (2) JBL PB12 Now I have a perfectly good AR2C that needs a good home. I would consider a trade for two JBL N Center ll speakers or a couple hundred dollars if anyone is interested.
