Replacement/Upgrade for R50 tweeter (SL1902)

superstang

I have a pair of R50's from forever ago, which still sound great by the way. However, while installing my nice new polk center channel speaker, I found out that one of the tweeters died in the R50. I did some searching and called Polk and the said they had a replacement for $60 each (ouch that hurts). Given the age of the speakers that is a lot of money. I am sure that I only paid $100 each for the R50's new. I can find lots of Polk tweeters online for $40 pair. However they all seem to be 8 ohm. They look like much nicer tweeters. The SL1902 in the speaker has a tiny magnet where as newer ones are much more substantial (not that it matters much in a tweeter). I measured the one working tweeter and the multimeter read around 3 ohm, which I would guess it is a 4 ohm tweeter.

Does anyone know what the specs for the SL1902 tweeter are? I believe the RD1503-1 is what the newer model (http://forum.polkaudio.com/discussion/74763/replacement-tweeter-for-r40-floor-speakers).

Have you found a replacement? I'm interested in the specs on the SL1902 also, I'm trying to repair a set of R10's. Can you check impedance of just the working tweeter unplugged from the circuit? Thanks!

No I have not. I am just using them without it right now.

Hi, first post and sorry to bump an old thread, but I can't find the full specs for the SL1902 (or newer equivalent RD1503-1) tweeter anywhere - does anyone have access to them? thanks
