G'day, I just picked up a couple of old 12" Rola speakers, partly on @fezz parka's advice, and I'm wondering if anyone here can tell me anything more about them. I bought them because I was looking for something affordable and Alnico to put into a 5E3 clone I'll be building soon. I only need one, but they were cheap enough that I bought them both. Codes on the frames are 258809 & 258020. DC resistance is 7.5-ish ohms. I'm trying to work out: A) Their age... judging by the stamps one is either 1958 or 1968 and the other is 1950 or '60 and; B) How much power they'll handle. The seller said 'around 20W' but he couldn't be sure. He imported them from the US, and said he thought they were originally in jukeboxes. A thread at the Les Paul Forum I found by searching for the cone stamp (42H1702) suggests they'll be at least half-decent for a guitar amp: "Cone number 42H1702 are guaranteed 1.29" voice coil, these work really well for guitar in the original coning if they're not rubbing." It goes on to say they might hold up to a Gretsch 6156 which AFAIK is around 17W. Of course, this is only one guy's opinion, so I'd really like to find out more about them to see if I can get a definite answer on their power rating. Some pics below... If you know of a good online resource with info on old Rola speakers, or if you know a bit about them yourself I'd really like to hear from you. Thanks .
