I'm looking for a certain model of LS3/5a speaker. It's the ones produced in the late 80s that were 11 ohms, although often the data sheet on the back of the speaker still refers to 15 ohms. Also, if you remove the grille, the B110 bass driver is NOT front doped (no swirly black stuff painted on). If you can help please send me a private message, as I have been subject to hijacking in the past. I am aware of Ebay. Thanks.
