Infinity RS10?

[GnRNut]

I got these pair a long while back anyhow, I was reading the reviews on audioreview.com again and I'm a bit confused... people left comments about the speakers being heavy and one guy left a comment saying they had 10" woofers...

I don't know when mine was made but they're bookshelfs with a 1" polydome cell and 6.5" tweeters

The RS or "Reference Series" has been heavily recycled by Infinity over the years with about eight different series carrying the moniker that I am aware of and likely double that number have come to be. For the RS-10, there were in fact four different RS-10s -- three speakers and one subwoofer.

Your RS-10s sound like the 1982 version (http://www.infinity-classics.de/infinity/models/Reference-series-1+b-2-10+A+B-1981-86/Reference-Standard-9&10/body_rs_9_10.html):
