Identifying your vintage tweeters
As we all know, the tweeter tells a lot about how old or what model your vintage Polk speakers are. The concept of this thread is for people to post detailed pics of their SL 1k/2k/2.5k tweeters, and what speaker they are from.
I'll start. This is an original SL1000 tweeter from a Monitor 5jr speaker, dated Feb 23, 1984-
When I bought the speakers, there was also one that had a warranty sticker on it. The front looked exactly the same, and the back had this sticker-
Anyone else? I'll take a pic of my SL2500's in my Monitor 10 Series 2's when I get home.
Polk Sl1000 & SL2000 tweeters
I don't have a pic to add since I have four SL1000's in a pair of 1984 SDA-ll's. As for the RD0194-1, here is a quote from the instructions that come with it.
"You are receiving a replacement tweeter with the part number of RD0194-1, which is engineered to be the equivalent of the SL1000 and the SL2000, 1" dome tweeter's found on many of our Monitor, RTA and SDA series of speakers. The mechanical and electrical characteristics are the same, however there might be some relatively minor physical differences which can easily be dealt with."
The mounting instructions go on to say the original screw mounting holes might not line up exactly. As for my early SDA's, since the SL1000 is a smaller size tweeter, I will have to slightly enlarge the tweeter mounting cutout area. and relocate the mounting screw holes.
I know this topic has been covered to death, but I thought this post might help clear up any confusion as to what the RD0194-1
can be installed in.
