Greetings, all. Great to find this forum.
I bought my Polk Audio Monitor 10's back in 1987 and I've loved them ever since. I've moved about a dozen times since then, always taken the Polks with me, and they're real survivors and still sound great.
I have a couple of questions -
1) How can I tell if these are 10A or 10B's? I've long forgotten which I bought. On the back of the speakers are the numbers "10 160240."
2) I'm thinking of upgrading the speakers. Can anyone recommend something that would be a noticeable improvement in sound and volume but not too terribly expensive? I use a Luxman R-115 tuner/amp with the speakers, purchased at the same time.
